At NAFS Technologies, I lead technical delivery across SiteBeacon, Spellman, and PMS, guiding 5–6 engineers through architecture, reviews, troubleshooting, and releases. I own production services built with NestJS, FastAPI, and ASP.NET Core on AWS and Linux.

I scaled SiteBeacon to 6,000 jobs per day with Redis and BullMQ scheduling, delivered 30+ multilingual Sitefinity widgets for Spellman, and replaced PMS's manual Excel workflows with connected applications supporting 100+ concurrent users.
