What I'm looking for

I'm open to full-time, contract, or freelance work building backend and AI-agent systems, including agent orchestration, model routing, evaluation, observability, and business workflow integrations.

At Osnova, I built a multi-tenant NestJS/PostgreSQL backend and React dashboard for a SaaS AI-agent platform, enabling operators to deploy agents across website, Outlook, and email workflows. I also owned releases across three Azure environments and implemented tenant isolation with JWT and Postgres row-level security.

I've built LLM-agent assessment systems for Woolf, reducing workflow cost and latency by about 40%, and founded ASRP, where I architected shared microservices infrastructure for a 14+ product research holding and built a six-engineer team.
