About Me

My name is Paweł Poradzisz, and I’m a software developer with extensive experience in building backend systems, API integrations, and data-driven web applications using Python and Django. Over the years, I’ve designed and implemented solutions that support logistics, fleet management, construction, education, and industrial operations.

I’ve worked on projects ranging from enterprise-level systems to small-scale internal tools and hobby projects involving Raspberry Pi and ESP8266. My work combines engineering precision with practical business thinking, focusing on performance, reliability, and maintainable code.

Areas of Expertise

• Backend development in Python Django / FastAPI
• Database design and optimization in PostgreSQL (including PostGIS)
• Integration with external services (e.g. Here API, Allegro REST API, e-TOLL)
• Application architecture and deployment in Kubernetes / Docker environments
• Automation of data and business processes
• Development of ERP, SCM, and Fleet Management systems

Professional Background

I currently work as a Senior Python Developer at Biuro Usług Informatycznych Informer, where I design, implement, and integrate software systems for enterprise clients. My work involves building robust backend architectures, optimizing database performance, and maintaining integrations with large-scale external APIs and ERP systems.

Selected Projects

• Route Optimization System – built on jsprit and PostgreSQL for a major pharmaceutical wholesaler (Medicare-Galenica).
• Fleetgo – fleet management platform integrating e-TOLL, built with Django/FastAPI in Kubernetes environment.
• Utility Solutions – infrastructure project management system for Australian Utility Solutions, with PostGIS and Geoserver API.
• SGM and Ewidencja – warehouse and asset management systems for PGNiG, integrated with SAP.
• JPK – web app for managing and transferring the Polish Standard Audit File for Tax (SAF-T).
• AllegroGD – automatic price and stock updater for Allegro, integrating market data via Allegro REST API.
• gor-dom.pl & monika-matematyka.pl – websites built with Django, Wagtail, and Mezzanine.

Work Philosophy

I believe that good code is readable code — designed to last and evolve. I focus on simplicity, transparency, and efficiency. Every project is an opportunity to learn, improve, and deliver real value through technology. Collaboration based on trust and technical integrity is key to my approach.

Beyond Coding

Outside of work, I enjoy electronics and DIY projects — especially tinkering with microcontrollers and automation tools. I also share my knowledge by teaching programming in C++, Python, and Bash to students and junior developers.
