I build and ship product features end-to-end: from idea → architecture → implementation → shipping → iterating with real-world customer feedback.

• AI-assisted product features (agents, retrieval, evaluation workflows)
• Backend APIs and services (clean contracts, pragmatic architecture)
• Event-driven systems and integrations
• Observability-first systems (metrics, logs, traces; debuggable by default)
• Developer experience (SDKs, tooling, paved roads)

• Strong ownership, fast iteration, and clear communication
• prefer boring, reliable solutions (and I know when not to)
• care about maintainability: tests where they matter, docs where they help
• like tight feedback loops: instrument, ship, observe, improve

• Product engineering in the AI space (agents, retrieval, evals, guardrails)
• Building systems that are simple to operate and hard to break

• Core: Python, Go, Rust, TypeScript
• Data: Postgres, MySQL, SQLite, Redis, Qdrant
• Infra: Linux, Docker, Kubernetes, Terraform, Helm
• Messaging & async: Kafka, RabbitMQ, SQS/SNS, Temporal, DBOS
• Cloud: AWS (primary), plus Azure/GCP when needed
• Observability: OpenTelemetry, Prometheus, Grafana, tracing/telemetry-first debugging
• AI systems: RAG/search workflows, evaluation harnesses, retrieval quality loops, guardrails

Open to product engineering roles at early-stage startups (especially in the AI space).
