  • Distinguished Product Engineer, Data and AIJul 2026 – Present
  • Principal Engineer & Engineering Team LeadApr 2022 – Jun 2026
  • Software EngineerFeb 2021 – Apr 2022
  • Shipped Luna, our agentic intelligence layer, so customers can talk to their data, get proactive insights and get things done in epilot, with the governance energy companies need. Every product team builds its AI features on it.
  • Moved our data from Redshift and InfluxDB to ClickHouse and turned it into Data Lake as a Service, a paid product customers plug their own BI tools into. Loading data into those tools went from over 30 minutes to under 3.
  • Helped move epilot off the legacy monolith and laid the foundation for the platform's serverless rewrite on AWS.
  • Brought in Vigilos so customer success, sales and ops answer data questions in Slack instead of filing engineering tickets.
  • Rolled out Leidang's coding agents to every team: routine fixes arrive as draft PRs instead of interrupting product work.
  • Building the AI tooling, rules and guardrails that let people outside engineering contribute with AI.
