SUMMARY

Seeking remote leadership role in security or platform engineering. Engineering Manager who secured payment systems and cut oncall incidents by 90%. Reduced workforce cycle times 20x and enabled non-technical QA to deploy independently. Shipped a risk engine that neutralized a card-testing botnet with near-zero false positives. Author of open-source libraries like tiny-cbor (800k+ downloads/wk).

EXPERIENCE

EatStreet — Madison, WI
Engineering Manager & Team Lead | Feb 2021 - Present
  - Hired and grew a 9-person remote platform team from junior to autonomous engineers, including performance management and PIPs. Directed platform architecture that cut other teams' build times from 5 min to 15 sec and gave QA self-service deploys. Project recognized at the executive level.
  - Designed an interchange model across 5 POS platforms to resolve data incompatibilities. Mentored the team through implementation. Error rates improved from 30% to under 1%.
  - Built a real-time risk engine on Redis to prevent further automated (500 card tests per minute) payment abuse. Profiled timing, account age, and API patterns. Near-zero false positive rate.
  - Secured JetBrains AI for every engineer. Evaluated Copilot and Cursor on own time; identified safe patterns. New contributions started shipping with test coverage via AI generation.
  - Core monolith took 10–15 min to build and dev environments broke weekly. Directed Docker, build caching, microservice templates, and SPA infrastructure. Frontend waits fell to seconds.
  - Incomplete captcha coverage and no email verification enabled credential stuffing and bot abuse. Redesigned unified auth across web, mobile, and restaurants with OAuth for a key partnership.
  - Built a tokenized payment API to strengthen card data handling. Directed app teams across mobile and web to migrate. Offloaded card data from infrastructure, reducing PCI scope.
  - New teams stalled on architecture and deployment. Embedded directly, diagnosed blockers via 1:1s, and built reusable project templates. New projects launched in days instead of weeks.
  - Built PCI Level 2 compliance program from scratch; passed year-over-year QSA audits.
  - Deployed YubiKeys for 50 privileged staff; enforced WebAuthn policy across OneLogin and AWS.
  - Created a bug bounty program funded by C-level with severity criteria, SLAs & payouts ≤ $1,500.
Sr. Software Engineer | May 2017 - Jan 2021
  - Owned end-to-end integration for Order with Google (Search/Maps food ordering) as a pioneer partner, driving 30%+ of company revenue for years.
  - Scaled order pipeline from single-server to clustered architecture for 3x pandemic traffic surge.
  - Built custom HTTPS infrastructure serving 3,000+ restaurant domains for $60/mo vs $2,700/mo.
  - Rebuilt security after data breach — bcrypt migration, encrypted bank data, HaveIBeenPwnd checks.

Epic Systems — Verona, WI
Software Developer | Jun 2014 - March 2017
  - Designed HL7 integration for reference lab orders and results, processing 10,000+ tests/month.
  - Represented clinical lab in cross-org HL7 councils, aligning report standards for patient safety.
