01About

// summary.md

I work on the unglamorous parts of the internet, the APIs and control planes that everyone depends on but nobody notices. Go, SQL, and Kubernetes on the surface; systems debugging and quiet incident response underneath.

At Cloudflare, I shipped features for large enterprise customers and owned services end to end: from spec and code through rollout, on call, and postmortems — including technical leadership on design, scoping, and safe rollout for customer-facing control-plane work.

Over the last few months I've gone all in on AI native development with Opencode + Claude, Opus for architecture and planning, Sonnet for the loop.

I care about systems that are observable, rollouts that don't drop connections, and code reviews that actually change minds. Based in the SF Bay Area, open to senior IC roles.

Systems Engineer

Cloudflare
San Francisco Bay Area, CA
  • Designed and shipped Go services on Kubernetes, powering APIs that operate on Cloudflare's global edge, a network that averages tens of millions of HTTP requests per second.
  • Adopted an AI-native development workflow using Opencode with Claude (Opus for architecture, project planning, code generation, and iteration), measurably faster from spec to production.
  • Provided technical leadership on PostgreSQL-backed control planes for IP address management and BYOIP (Bring Your Own IP). SME for geolocation APIs and customer-facing BYOIP onboarding workflows. Stack: Go, Kubernetes, Prometheus; ClickHouse pipelines to propagate data to rest-of-world regions.
  • Shipped features for large enterprise customers, translating their requirements into functional specs and code in production.
  • Contributed to engineering behind the Cloudflare blog post "Your IPs, your rules: enabling more efficient address space usage," covering dynamic prefix allocation.
  • Owned production services through the full lifecycle: on-call rotation, incident response, postmortems, and follow-through on action items.
  • Drove safe rollouts of infrastructure changes across Cloudflare's global server fleet without disrupting traffic.
  • Supported teammates through design reviews, on-call pairing, and incident retrospectives — helping others ramp on control-plane codepaths and operational runbooks.
Aug 2018 to Feb 2022 3 yrs 7 mo

Software Development Engineer

Applied Systems Engineering
Campbell, CA
  • Built data extraction pipelines converting unstructured network protocol output into structured, queryable datasets ready for machine learning workflows.
  • Designed a machine learning classifier (Python, support vector machines) that identifies SCADA substation connections via network signatures and auto-retrieves the correct configuration files, cutting field engineer onboarding time by 90% and eliminating config-mismatch errors.
  • Worked directly with customers to validate new features and contributed to product roadmap discussions.

Software Engineer Intern

Delta Electronics
Fremont, CA
  • Built OpenHardwareAPIs, a Python library that controls bare-metal switch hardware. Open-sourced under DeltaProducts/OpenHardwareAPIs.
