What I'm looking for

I’m looking for a remote-first team where engineers own what they build and ship often—roles focused on end-to-end product delivery and AI agent systems (LLM routing, RAG memory, observability) without sacrificing frontend performance.

I’m a full-stack engineer with 8+ years shipping products end to end across frontend, backend, APIs, and production operations. For the last ~1.5 years, I’ve been the lead AI / full-stack developer on Nexa (an AI pet-companion + AI-creation app), building agentic systems in TypeScript—tool-calling image-generation, multi-provider LLM routing with failover, and a pgvector RAG memory system with per-channel isolation.

I take products from build, deploy, and launch to the App Store and Google Play, working across React, React Native, TypeScript, and Node.js / NestJS with strong REST API fundamentals. I instrument what I build (token/latency/cost ledgers, behaviour-locking tests), and I do my best work in small, communicative, remote-first teams where engineers own what they build and ship often—I’m also a certified Senior System Architect.
