Product Engineer (AI)

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

What I build

  • 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)

How I work

  • 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

Current interests

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

Toolbox

  • 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).
