About
I build systems that stay fast at scale and ship on time.
Over 5+ years at PixelPlex, Syberry, and Linnovate, I've owned architecture at scale: 216 isolated databases, 109M+ records queried in under 5 seconds, and a production LLM media-processing engine shipped in 60 days.
I work across Node.js / TypeScript, PHP / Symfony, and React — with a focus on clean boundaries, measurable performance, and AI features that are safe to run in production.

PostgreSQL Partitioning at 109M Rows
A critical report on 109M+ telemetry rows took an hour. Hardware-aware partitioning cut it to under 5 seconds. The real decisions behind a 720x speedup, no theory.
NestJS + BullMQ at Scale
I shipped an event-driven NestJS + BullMQ pipeline to production in 60 days. What actually breaks first at scale: retry storms, lost jobs, queue starvation, and the fixes that hold.
