Profile Summary
- Senior Technical Product Manager with 8 years of experience owning public APIs, CLIs and developer platforms for enterprise engineering teams and individual developers, specializing in API design, platform roadmaps, and version migrations.
- Fluent in API standards (REST, OpenAPI), cloud infrastructure (AWS, Kubernetes), observability (Datadog), usage analytics (SQL, Looker), and specs and planning (Jira, Confluence), working through RFCs, ADRs, and OKRs.
- Deep expertise in API contract design, rate limits and quotas, SLOs and error budgets, and deprecation policy, using a written RFC for every breaking change and usage data behind every roadmap call to ship APIs developers adopt and keep using.
- Works daily with staff engineers, SRE, developer relations, security, and solutions engineering across 4 platform teams that ship every week, running design reviews, API office hours, and launch readiness checks.
- Raises the bar on API consistency and spec quality by chairing the cross-team API design review, coaching 3 newer PMs, and keeping the public API style guide current.

Education
Work Experience
- Set the 2-year strategy for the Postman API and CLI, which enterprise teams use to run API tests in CI, and split the roadmap of 4 platform teams between new endpoints, scale work and tech debt, growing monthly API calls from 1.9B to 3.4B.
- Wrote OpenAPI specs and technical PRDs for 31 new endpoints with the API platform engineers, covering resource models, error codes and pagination, and raised specs approved in their first review from 52% to 88%.
- Ran a weekly design review with staff engineers on rate limiting, caching and multi-region options, recording each call in an ADR across 24 RFCs, and cut the time to a design decision from 3 weeks to 6 days.
- Interviewed 52 developers and QA leads who run collections in CI pipelines and sorted 1,400 GitHub issues and community forum threads by theme, which put CLI install failures at the top of the next quarter’s roadmap.
- Rebuilt the API quickstart, the CLI install guide and the sample collections with Developer Relations, testing each draft with new users, and cut median time to a first successful API call from 17 minutes to 5.
- Defined the API’s core metrics (weekly active API keys, calls per workspace, error rate by endpoint), wrote the SQL behind the Looker dashboards, and grew weekly active API keys by 41% in a year.
- Set SLOs and error budgets in Datadog with SRE for the 12 busiest endpoints and saved 2 sprints a quarter for fixes from incident reviews, cutting p99 latency from 820 ms to 510 ms.
- Retired the old monitors endpoints with a 12-month sunset plan, migration guides and in-app warnings, moving 2,300 enterprise integrations to the new version before the shutdown date.
- Owned the roadmap for the server-side SDKs in Go, Java, Python and Node.js, shipping 4 major versions with migration guides and cutting SDK support tickets by 35%.
- Built a usage report on server-side SDK connections in SQL with Finance and the data team, which became the basis for usage-based pricing on 3 enterprise plans.
- Ran a quarterly developer survey and 30 calls with backend engineers and SREs, which put stale flag cleanup on the next year’s roadmap as its own project.
