Summary of Qualifications

Staff Software Engineer and Technical Architect with 33+ years building production systems in finance, network security, and insurance. I work full-stack with Ruby/Rails, React/TypeScript, and Python across AWS and GCP - researching approaches before committing to designs, writing architecture docs that span team boundaries, and teaching what I learn through presentations and pairing. I review 3-10 PRs daily with a focus on testing and problem-solving, and I stay sharp on emerging tech through a personal knowledge system with thousands of notes. I built Career Companion, an AI-powered job-fit engine that lets recruiters explore my experience conversationally; one of several LLM tools I've written code for, not just read about.

Professional Experience

Simply Business
Oct 2022 - Present
Staff Software Engineer
Late 2023 - Present
Team: Atlanta Assurers
  • Explored before building: trained a Bayesian classifier for cross-sell recommendations, prototyped chatbot architectures, researched carrier APIs, and built LLM-assisted workflows into daily work. Used LLM self-review on design docs to catch real implementation bugs before any code was written.
  • Worked across team boundaries: wrote architecture docs spanning multiple teams, managed the V3-to-V4 API migration lifecycle end-to-end, decomposed multi-team initiatives into parallel-friendly workstreams with explicit dependency graphs, and presented architecture decisions in the Architecture Decision Forum.
  • Taught what I learned: gave 10+ presentations (functional programming monads to practical LLM techniques), ran the engineering book club, paired regularly on testing and debugging, and built reusable AI prompting tools I shared with other teams.
  • Still shipped code: reviewed 220 PRs in Q1 2026 (275% of goal) across 5+ teams, built features end-to-end from refinement through cleanup, and handled the usual landing page fixes, validation logic, and frontend bugs.
  • Kept an eye on risk: found and removed insecure code patterns before they became problems, took regular turns on production support rotation, and helped other teams debug their Airbrake alerts when things got busy.
