Andrzej Oblong¶
Product builder. AI-first. 15 years in IT.
I build software, solve hard problems, and help teams ship things that actually work.
Currently available for freelance contracts, consulting, and mentoring — remote, EU and UK.
What I do¶
- Python development — backend systems, APIs, automation tooling, data pipelines
- Full-stack products — Python + React, from idea to working software
- Platform & DevOps — CI/CD pipelines, Docker, GitHub Actions, GitLab CI, Jenkins
- AWS infrastructure — architecture, cloud migration, security, cost control
- Quality engineering — test strategy, automation, performance testing — built into the process, not added at the end
- Mentoring — 1:1 or team, sharing what 15 years in IT actually taught me
Featured project¶
Cycling Trainer Hub¶
A full-stack indoor cycling training platform, built solo from scratch and used on my own bike, week to week.
BLE/ANT+ sensor integration (power meters, smart trainers, HR straps) with real-time ERG control, HRV-based readiness scoring, FTP/ramp testing, structured training plans with dynamic load management (CTL/ATL/TSB), route simulation, and Zwift workout import — plus native iOS and Android apps.
It also ships an AI coach: a tool-using LLM agent that reads your live training data and plan, answers questions in chat, and — the part I wrote up separately — talks back. Push-to-talk voice Q&A mid-workout, answering with real numbers pulled from the live session, not canned lines.
What makes it interesting: it was built AI-first — the AI was in the room from line one, not bolted on afterward. The result is a working product I actually use, not a demo.
