What I'm looking for

I want to build production-grade LLM agents and RAG systems on reliable distributed infrastructure—owning architecture, contracts, and authorization end-to-end—with strong observability, durability, and evaluation-quality gates.

I’m an AI/ML engineer and backend builder who designs distributed, event-driven systems for scalable production outcomes—using CQRS, Kafka, Temporal, gRPC/Protobuf, and multi-tenant authorization. I’ve owned contract-first gRPC/Protobuf APIs across 5+ services and implemented replay-safe, exactly-once-adjacent patterns like transactional outbox publishing and durable, replay-safe workflow context propagation.

On top of that infrastructure, I’ve extended into AI/agent systems—building LLM agents, RAG pipelines, and evaluation harnesses that stay observable, reliable, and production-ready with OpenTelemetry. I’m particularly driven by authorization that holds under adversarial conditions, having designed a Zanzibar-style OpenFGA/ReBAC model (and an auth proxy) to enforce permissions on every agent tool call, plus durable runtime components like agentctl for crash-resumable, eval-gated execution.

Scaled backend services from 1K to 100K users using an nginx reverse proxy with IP-hash load balancing. Improved performance with PostgreSQL connection pooling, implemented MFA and email verification, and built REST/GraphQL APIs with a MongoDB-backed event-logging pipeline.
