November has arrived, bringing another opportunity to support those in need as part of the #SidnetDonations campaign. This time, Patryk has chosen the Open Cages Association and the Kolibri educational platform.
Third Anniversary at Sidnet
Patryk recently celebrated the third anniversary of our fruitful collaboration. During this time, he has established himself as a skilled Frontend Developer, with productivity and a work ethic that is second to none. He navigates React, NextJS, and TypeScript with remarkable ease and has an exceptional eye for detail—nothing escapes him, and projects are always polished to perfection.
Kolibri – Time to Say Goodbye to Educational Exclusion
Educational exclusion is a serious problem that hinders children and young people living in remote, poorly connected areas with limited access to educational materials. Kolibri, an open-source educational platform designed and managed by Learning Equality, aims to address this issue. Technology-based yet operating on an offline-first model, Kolibri provides a solution to gaps in educational access and the lack of internet connectivity.
Open Cages Association – A Chance for Animals
Industrial animal farming, while considered by many to be an essential part of the economy, is also an area where abuse and even crimes frequently occur. The Open Cages Association has set itself the goal of driving systemic changes and regulations to curb illegal and unethical practices in farming, ensuring the highest possible standards of animal welfare. At the same time, the association actively promotes a vegetarian lifestyle, educating the public that meat and animal products are not as essential to us as we have become accustomed to believing.
Soon, in December, we’ll have the holiday #SidnetDonations – join us in watching for the first star.
In October, on the occasion of his 15th work anniversary, Krzysztof Pisera decided on where the support from the #SidnetDonations campaign should go. The funds will be donated to the “Little brothers of the Poor” Association and the Python Software Foundation.
The Loyalty
In Sidnet’s 20-year history, there are still employees who have been with us almost from the very beginning and helped shape the first chapter of our company. This month, Krzysztof is celebrating his 15th work anniversary. Over the past decade and a half, he has repeatedly proven himself to be an excellent developer, a dedicated manager, and a responsible leader. For nearly half of that time, he has served as COO, ensuring that every process within Sidnet runs smoothly and without obstacles.
Python Software Foundation – The First Choice for Many
As one of the most popular programming languages in the world, Python is the go-to choice for many developers. It has had a tremendous impact on Krzysztof’s professional life, and even now, after many years, it remains his preferred language. Python is managed as an open-source system by the Python Software Foundation, which not only ensures the continuous development of its infrastructure but also provides a platform for a vast global community of users.
“Little brothers of the Poor” Association – Support for Lonely Seniors
The charitable organization receiving funds in October was part of our initiative many years ago. That support led to a partnership that continues to thrive to this day. Life in one’s later years is not easy, especially when old age is accompanied by loneliness. The “Little brothers of the Poor” Association was founded to support seniors struggling with feelings of abandonment. Regular visits from volunteers, a helpline, group meetings, and the “Gift a Christmas Eve” campaign, which has been running for two decades, help remind elderly people that they are not alone in this world.
In November, we will reveal more organizations that will benefit from the #SidnetDonations campaign – stay tuned!
As autumn approaches, so does the September edition of our #SidnetDonations initiative. This month, we’re proud to support two causes close to Dawid Jancen’s heart: the animal shelter in his hometown of Tczew and the continued development of the LibreOffice suite.
A Journey of Nearly a Decade
Dawid’s journey with Sidnet is a classic “from zero to hero” tale. Starting as a self-taught junior developer, he quickly rose through the ranks, earning recognition not just as a talented Web Developer with a flair for single-page applications, but also as a compassionate and helpful colleague. Since day one, Dawid has been a key player in our projects for one of our largest clients, THG, and he’s soon approaching a milestone – ten years with Sidnet!
LibreOffice – Empowering Everyday Office Work
While many businesses rely on paid office software, Dawid’s passion for open-source solutions has long made LibreOffice his top choice on both his work and personal devices. In his words, it’s an alternative that “more than meets the needs of most users in terms of functionality.” LibreOffice is available in 110 languages, and if Dawid’s endorsement isn’t enough, consider that countless public institutions worldwide rely on the suite for their daily operations.
Helping the Four-Legged Friends in Tczew
This month’s donation recipient comes as no surprise – Dawid once again chose the animal shelter in Tczew, demonstrating his deep love for animals. The shelter depends on fundraising and volunteers, yet its needs often outpace the available resources.
You too can make a difference. Support the fundraiser organized by OTOZ Animals Shelter in Tczew. Your contribution will help provide food, medicine, veterinary supplies, life-saving procedures for injured animals, and much-needed improvements to the shelter’s facilities.
Stay tuned for October, when we’ll announce the next organizations to benefit from the #SidnetDonations project!
After celebrating the 20th anniversary of Sidnet with a post summarizing our team values, we are moving from words to deeds and presenting the next edition of the #SidnetDonations initiative. This time, the funds will go to Marcin Sztrubel, a beneficiary of the Avalon Foundation struggling with muscle atrophy, and to the development of the pre-commit framework, as nominated by Wojciech Siewierski.
Eighth years with us
In times when frequent job changes have become the norm, we proudly celebrate the work anniversaries of our team members. Wojciech Siewierski, who has been with us for over seven years, embodies the dedication and expertise that are the bedrock of our company. Privately, he is a connoisseur and expert on yerba mate and the hottest extremes on the Scoville scale. Professionally, he is an experienced Senior Developer, a cybersecurity specialist, and a genuine technical wizard. His expertise has been pivotal to countless projects, both for our clients and within the company. This time, we have entrusted him with the important task of choosing the open-source and charity projects we will support.
Pre-commit – streamlining Continuous Integration
To err is human, but with frameworks like pre-commit, small developer mistakes—like missing semicolons and other minor, easily fixable defects—are caught early. Pre-commit significantly reduces the workload compared to manually writing Git hooks, especially given the myriad states a repository can be in. This framework automatically runs tests whenever changes are saved, simplifying the code review process by allowing reviewers to focus on the most critical aspects of the modifications. By ensuring that tests and linters are executed in a structured and predictable manner, pre-commit helps prevent errors from coming to light.
The Foundation supports its beneficiaries in many ways. For example, it offers much-needed material support, but also psychological and organizational assistance to make life easier for those struggling with cancer on all possible levels.
Marcin Sztrubel – rehabilitation of muscle atrophy
Fundraisers for children with disabilities naturally stir deep emotions, but their visibility often overshadows the struggles faced by adults dealing with similar challenges. This month, Wojtek has once again chosen to support Marcin Sztrubel, who has been confronting the relentless progression of muscle atrophy for several years.
Marcin does not give in to the disease and is actively involved in the Polish Neuromuscular Diseases Association. However, the escalating costs of his rehabilitation are becoming an increasing burden. We hope that the support provided through the #SidnetDonations initiative will bring him at least some relief.
You can also help Marcin by donating any amount to the Avalon Foundation, where he is a beneficiary. The necessary details can be found on the foundation’s website, and to ensure the funds go directly to Marcin, please title your transfer “Sztrubel, 406,” according to the instructions.
That was the August edition of #SidnetDonations – stay tuned for September, when we will introduce the next foundations and open-source projects to receive our financial support.
Tell me you’re part of the Sidnet team without telling me you’re part of it. Despite being spread across Poland (and beyond), with a wide range of interests (running, making music, farming, woodworking, watercolor painting… the list goes on), and—which often leads to spirited discussions—having varying preferences in code editors, the members of the Sidnet team share common traits.
To celebrate the company’s 20th anniversary, we’ve taken a deeper look at the values that unite our 37‑member team.
Driven by Dev Project Challenges
We embrace all types of projects—whether they involve R&D work, long‑term commitments, or emergency takeovers from other providers. We’re eager to support clients from the concept stage, often analyzing dozens of scientific articles and creating our own machine‑learning models. We quickly adapt to the latest algorithms and technologies—AI, Big Data, Computer Vision, and Unreal Engine 5.
At the same time, we ensure our clients are never left unsupported. We step in to take over poorly managed technological projects and work to get them back on track. We’re also committed to long‑term software maintenance—a prime example being the Kujawski brand’s Blogi z pierwszego tłoczenia (“First-pressed Blogs”), which we supported for 16 years!
Programming extends beyond our professional lives—many of us develop and use technological solutions for personal projects every day.
We Prefer Remote Work
At Sidnet, we normalized remote work years before the pandemic. While we appreciate occasional in‑person gatherings, the daily commute to the Warsaw office is often inefficient and, in many cases, unfeasible. Our commitment to 100% remote work has allowed us to connect with valuable team members from diverse locations, including Rzeszów, Berlin, and even Canada.
We Embrace Development Opportunities
Learning new programming languages, taking on managerial roles in projects, and seamlessly transitioning from non-technical to technical positions—these are commonplace at Sidnet. We have numerous examples where these opportunities have led to successful and fulfilling outcomes for everyone involved.
“I joined Sidnet as a content marketer. With the support of the employer, I was able to grow in unexpected areas, acquire new skills, and find my ideal role. Over the past 6 years, I’ve had the chance to prove myself in roles such as brand communication manager, employer branding specialist, graphic designer, UX researcher, manual tester, project manager, and ultimately, product owner. The English classes sponsored by Sidnet also empowered me to manage product development while communicating effectively in English,”—says Olga Muzyczuk.
We Develop Open‑Source Solutions
We have a strong affinity for open‑source solutions. In both our internal tools and client projects, we primarily use open‑source software, adjusting it to meet our needs and frequently sharing it on GitHub for others to benefit from.
But that’s not all—each month, we donate to an open‑source project chosen by a team member. Since 2012, we’ve contributed nearly 150 financial donations to the development of projects such as Django, Next.js, Strapi, Linux, Git, and Jenkins.
We Make the World a Better Place
We know how cliché this phrase is. And yet the list of evidence keeps growing.
Alongside our monthly donation to an open‑source initiative, we also provide financial support to a non‑profit project selected by one of us. Over the past 12 years, we’ve supported associations, foundations, hospices, shelters, and individuals in need nearly 150 times.
Our latest initiative involves planting trees to commemorate client anniversaries and project milestones. We’re starting with a bang—celebrating our 20th anniversary, we donated funds to plant 200 trees. You can track our progress on the Posadzimy.pl website.
Under the Sidnet Donations initiative, our monthly financial support goes to projects and public benefit organizations that are close to our hearts. This time the choice belonged to Marcin Tabaka, who decided that we would support the Cancer Fighters Foundation and the Django REST Framework.
Happy thirteen
There are employees and there are EMPLOYEES – Marcin Tabaka recently celebrated his thirteenth anniversary of employment at Sidnet and during this time he has become known as an excellent Lead Full Stack Developer who not only contributed to many project successes in our company but also had a significant impact on its development as a whole.
Described by his colleagues as the life of the party, he spreads a positive attitude and encouragement – nothing is impossible for him. He is a real team player… until a board game appears on the table – then the competitive spirit comes out of Marcin.
Django – freedom and convenience
Every month, we support one open source project – this time we chose an add-on to the Django framework – Django REST Framework. Marcin has been working with Django technology for years and is so closely associated with it that he already chose it as a beneficiary of our donation a year ago. This time, due to the frequent use of the DRF tool to conveniently create APIs in applications, Marcin decided to narrow down the selection.
Marcin’s loved ones struggled with cancer in the past, so his choice of a public benefit organization is not surprising. The Wrocław-based Cancer Fighters Foundation supports both adults and children battling cancer. Marek Kopyść, the founder who himself won the fight against cancer, wants to remind people that cancer is not a death sentence – it is just an opponent that can be defeated!
The Foundation supports its beneficiaries in many ways. For example, it offers much-needed material support, but also psychological and organizational assistance to make life easier for those struggling with cancer on all possible levels.
Together we can do more – you can also provide support
The aid provided as part of the Sidnet Donations campaign is a drop in the ocean of the needs of charitable organizations. We encourage you to support the organization also on your own – you can do it in several ways:
Direct donation via the Foundation’s website.
Joining the volunteer team.
Transferring 1.5% of the tax to the National Court Register number 0000581036.
Participating in Cancer Fighters social media, e.g. on Instagram.
Involving your company in activities supporting the Foundation, e.g. fundraising.
Next month, we will share two more organizations that will receive #SidnetDonations from us – see you soon!
