What I'm looking for

I’m eager to leverage my technical expertise to drive innovation and enhance system scalability at Mercor.

At UN IAEA, I design internal web solutions for travel setup, analytics and reporting, and medical equipment certification. I also engineered LLM-powered applications using RAG, agent-based workflows, and Qdrant search for internal knowledge access and document analysis.

I’ve worked on .NET services and platforms at Chooose A/S, SoftInform A/S, Svitla Systems, Ciklum A/S, and Viacom LLC. My work has included developing carbon-offset platform services, advancing Salesoptimizer, and deploying AWS S3 media storage with secure upload and retrieval workflows.
