What I'm looking for

I’m open to remote global roles where I can build scalable backend, distributed systems, GraphQL, and production AI/RAG platforms while providing hands-on technical leadership.

At WOIS and PickMyBrain.com, I designed and owned 20+ Elixir/Phoenix microservices and delivered production RAG search using OpenAI APIs, pgvector, and semantic retrieval over video knowledge bases. I translated high-level architecture into domain-separated GraphQL APIs, event-driven RabbitMQ integrations, and AWS deployment standards.

Across 15+ years, I’ve led engineering teams and mission-critical retail, billing, logistics, inventory, payment, and ERP systems. I combine hands-on backend architecture with technical leadership, incident management, load testing, observability, and mentoring.
