Hi, my name is Andrzej
I build web applications. I specialize in backend and infrastructure, but I don't shy away from front-end work either.
I started out around 2009. Back then I built dynamic websites, intranet applications and marketing tools, written in PHP and MySQL.
A few years later I switched to Python and PostgreSQL. At the time I was interested in geographic information systems (GIS), where these tools are the most common choice.
In 2017 I joined Karkonosze National Park, where I spent four years in the GIS department, where I was responsible for the network, servers and systems. Among other things, I modernized the network and server infrastructure and launched a map portal built on ArcGIS Enterprise.
In 2020, while still working at KPN, I took on a side project: building a REST API with Django REST Framework and PostgreSQL. A year later I went back to programming full-time.
After two years as an employee, in 2023 I started my own business, and since then I have been working with clients as an independent contractor. I build web applications, mostly on the backend - business logic, APIs and integrations with other systems - but I also take on front-end work when needed. The other main part of my work is automation and the infrastructure around the web applications: deployments, backups, monitoring and maintaining the environments they run on.
