Ruby on Rails (primary)
10+ years building, maintaining, and scaling Rails apps - APIs, background jobs, database performance, and full-stack web.
About
10+ years shipping production software across web, mobile, and product infrastructure.
I build indie products, write about engineering trade-offs, and ship in public.
Based in Timisoara, Romania. Working remote. 10+ years in production Rails and full-stack delivery.
What I do
I treat software as a long game. The goal is not just launch speed - it is shipping systems that stay maintainable as users, requirements, and pressure increase.
This site tracks what I am building now. badarau.net is where I keep the full profile and portfolio context.
Background
Full-stack capability
JavaScript (React, React Native, Expo), Python, and Elixir. I can own backend, frontend, and mobile end-to-end.
Infrastructure and DevOps
AWS (EC2, RDS, S3, and more), CI/CD pipelines, deployment strategies, monitoring, and alerting. I make deploys boring in the best way.
Product engineering
Third-party integrations, mobile apps (React Native + Expo), performance optimization, security basics, and technical due diligence. I've been the solo engineer, the lead, and the outsider brought in to fix things.
How I work
- Understand before touching. I read the whole system before I change anything. Fixes without understanding just move the problem.
- Root causes, not symptoms. Patching the error message doesn't fix what's causing the error. I find and fix the actual problem.
- Ship, don't recommend. My deliverable is fixed code in production, not a PDF of suggestions.
- Leave it better than I found it. Tests for the risky paths, monitoring for the failure modes, and a clear plan for what comes next.
