Hire a Senior Full-Stack Developer
I'm Adrian Rusan, a senior full-stack engineer in Timișoara with 10+ years in production. I ship backlogs with AI agents and read every pull request myself before it reaches you, security first. Generation was never the slow part. Review is.
How I work
Day to day, I work in writing. You get the pull requests, my review notes and a short update, so nobody waits on a meeting. I learned to review on systems where mistakes show: live overlays for PGL Major streams watched by 2M+ people at once, and 300+ survey projects for global brands. I review agent code the same way. I assume it's wrong, then check. The agents run on my own harness: 20+ skills and 20+ hooks that scan for secrets, block destructive commands and refuse a merge when a check can't run. My own status board, for scale: 438 commits on 12 active days, 175 test files, 21 PRs, all merged.
The method, agents ship and I review, is on the home page. The full process, from scope call to handoff, is on the services page.

How the numbers are counted
- Agents give you 2–3x the throughput, not 100x, and they get specific things wrong. Here's what they get wrong.
- Workflow numbers: 463 sessions · 335 hours · 4,920 commits · 928 PRs opened (upper bound, not all merged) — 66 days, 6 Aug–10 Oct 2026, counted from my own session logs.
- Each case study says whether it's my own project or client work under NDA.
- This site checks its own claims: a test fails if a page says tests passed for a run that had none, and the build fails if a case study still has a placeholder.
