What I'm looking for

I’m looking to build production-grade backend systems and secure API/data pipelines while integrating AI/ML (including LLM agentic workflows) into customer products, partnering with teams to iterate fast in real-world, ambiguous environments.

I’m a Senior Software Engineer with 10+ years building and deploying production systems, APIs, and data pipelines in fast-paced environments. I specialize in integrating AI/ML systems—especially LLM-based agentic workflows—into customer-facing products that solve real problems.

I lead end-to-end solution delivery, from customer problem identification through secure third-party API and database integration. At Robinhood, I designed an AI-powered trading platform and delivered REST and GraphQL APIs using Go and Python, including OAuth2 and JWT authentication.

I thrive in ambiguous, field-driven settings, partnering with product, research, and data scientists to iterate quickly and ship production-grade services. I’ve scaled systems using Kafka event streaming, improved performance with PostgreSQL sharding and Redis caching, and strengthened reliability and observability with Prometheus, Grafana, and ELK—reducing MTTR and latency while maintaining secure integration patterns.
