What I'm looking for

I'm looking for remote work as an AI engineer: context engineering, agents and data-source integration for LLM products, mostly on .NET and Azure, built with security in mind from day one. Contract (B2B through my Ukrainian sole proprietorship) or full-time. Also open to AI security and application security roles.

Engineer with seven years of full-stack web engineering, mostly .NET and Azure: back end, front end, databases and cloud.

At CEATAEC (a Wilhelmsen group company, maritime logistics) I was acting tech lead and drove AI adoption in the product. I designed and built the context layer for its LLM features on Azure OpenAI: retrieval over documents and databases (chunking, embeddings, hybrid search, reranking), tool and function calling, agent memory and MCP, plus a multi-agent system in .NET. I also moved a monolith to event sourcing on Azure Service Bus with Polly for resilience, built resumable chunked file transfer over HTTPS for ships at sea, and owned the team's technical decisions, code review and release deadlines.

Security is part of how I build. In 2026 I was the sole security owner (contract) at a US fintech: I took over its SOC 2 Type II program in Drata, wrote the access governance, data governance, incident response and risk management policies, and ran an external penetration test from the client side. Through Aegis Logic Systems I publish security assessments of open-source AI agent frameworks, including a 25-control release gate for Dify.

I work remotely from Albania (CET) as a contractor through a Ukrainian sole proprietorship (FOP).
