CRM for a gas service company

DAVID STRATIL - SYSTEMS FOR PRODUCTION
I build systems for production
I'm David Stratil, a software developer and ML engineer based in Czechia. Every system I work on has to survive being switched on: data pipelines, field-service tooling, and agents that make decisions on their own.
I care about the quiet parts that keep it running - monitoring, recovery, and code that still reads clearly months later.

WORKFLOWProcess
- 01
Understand
The problem, the data, the constraints. I spend the time here so the next four steps are cheaper.
- 02
Design
The simplest architecture that survives real traffic. Draw it out, stress it, cut what is not needed.
- 03
Build
Clean code, tested where it matters. Small, readable modules a team can own without fear.
- 04
Ship
Automate the boring parts. Deploy often, roll back fast, and make a release an event, not an ordeal.
- 05
Maintain
Monitor, fix, improve, repeat. A system is done when it runs without me.
