What I'm looking for

I'm looking to build production backend and full-stack systems, solve reliability and security problems, and work on products with meaningful scale.

At CA Monk, I built an LMS backend from scratch across 20+ modules, shipping 150+ endpoints for web and mobile clients targeting 20k+ users. I also identified and helped fix 20+ API failures before launch, including authentication, pagination, and state-transition edge cases.

I’ve tackled critical payment, affiliate, enrollment, and access-control issues, including an IDOR vulnerability. I migrated five LLM workflows from OpenAI Assistants API to Langflow with zero downtime and an automated evaluation harness for output regressions.

Previously at Alquinox LLC, I built document annotation and key-information-extraction interfaces using HTML5 Canvas, OCR, Next.js, and typed backend-for-frontend APIs. I also build Go systems for geofencing, real-time WebSocket alerts, and Redis-inspired storage.
