What I'm looking for

I'm open to backend, platform, and AI engineering roles where I can build and ship LLM platforms, reliable infrastructure, and secure production systems.

I co-founded and led delivery of a multi-tenant SaaS chat platform at Synerry, taking it from prototype to launch in eight months with a five-engineer team. I built its Go and Fiber service layer on PostgreSQL and Redis, adding RAG search with pgvector, multi-tenant RBAC, WebSocket and SSE streaming, and Kubernetes delivery through Argo CD.

I also built a Rust AI gateway spanning seven model providers, consolidated development infrastructure onto bare-metal Proxmox, and led a 40-site government web migration in two months. Alongside client-platform delivery, I introduced Wazuh monitoring and ran SonarQube and OWASP ZAP in the release path.
