Summary

Senior software engineer with 10+ years building reliable software, developer tooling, and onboarding systems that make complex products easier for humans to use and easier for AI systems to operate against. Strong background across full-stack engineering, QA automation, internal documentation, and context-rich workflows that turn scattered knowledge into reusable team infrastructure. Especially effective where software, explanation, testing, and AI-assisted delivery meet.

As a QA Automation Engineer III, I lead the AI integration strategy for my QA team: authoring a version-controlled governance library, modernizing legacy test infrastructure on an adapter pattern, and coaching teammates on effective AI-assisted workflows.

Outside of that role, I build non-commercial AI tooling and agent workflow experiments — open-source prototypes focused on context design, developer ergonomics, and human-in-the-loop control, built through iterative pairing with Codex and Claude Code.

Experience

QA Automation Engineer III · Government Software Contractor

– Present · Remote

  • Lead AI integration strategy organization-wide, authoring a version-controlled governance library — Rules, Profiles, and Prompts that ship with test code — to standardize review quality and keep AI-assisted output reproducible.
  • Architected a legacy VB.NET-to-C# test migration on an adapter pattern that runs both Selenium and Playwright, decoupling test logic from drivers to unlock cross-browser coverage without rewrites.
  • Built an internal documentation app that measurably cut onboarding time to the codebase and AI tooling.
  • Drive weekly regression triage end to end, converting manual test paths into durable automated coverage for a mission-critical public-sector system serving millions.

Independent Web Developer · Ben Live / McNulty Web Apps

– · Remote

  • Delivered responsive full-stack web projects from first client conversation through deployment, support, and iteration.
  • Built reusable testing, documentation, and UI patterns that made small projects easier to maintain and faster to extend.
  • Translated ambiguous business requests into practical implementations across frontend, backend, and deployment work, working directly with clients on design direction and usability.

Personal Projects & Open Source · Independent, Non-commercial

– Present · Remote

  • Build non-commercial AI tooling, agent workflow experiments, and open-source prototypes focused on context design, developer ergonomics, and human-in-the-loop control.
  • Built and published Promptfolio, a catalog of 15+ iteratively refined Custom GPTs — including a Prompt Engineer / Prompt QA / Red Team trio that applies review-and-adversarial-testing discipline to prompt design itself — each documented with a scoped role and usage guidance.
  • Explore ways to make AI-assisted software work more reproducible through better prompts, clearer constraints, and reusable workflow scaffolding.

Frontend Engineer · Menuat · SaaS Startup

– · Hybrid

  • Shipped dynamic digital menu systems from concept to cloud-hosted production, owning frontend animation, content tooling, deployment, and support.
  • Delivered 100+ commercial menu-board layouts across convenience-store and fast-casual chains, tuning layout and density for diverse display hardware.
  • Bridged users, design, and backend teams as the frontend intermediary, translating brand requirements into responsive, accessible on-screen experiences.

Full-Stack Developer · Enix Networks

– · Tampa Bay, FL

  • Built responsive, mobile-optimized client websites in PHP, HTML5, CSS3, and JavaScript, working directly with clients on design strategy and rapid prototyping.
  • Programmed PHP page servers, contact forms, and data-security processes; ran cross-platform usability assessments before launch.

Selected Projects

  • AI Lab Product Suite

    Promptpad · Problem Solver · Agent Agenda · Decision Assistant

    Designed and implemented modular AI workflows with structured prompts, deterministic controls, and human approval checkpoints.

  • Pre-Deployment Quality Pipeline

    Playwright + Firebase Emulator orchestration

    Built test and review flows that catch regressions across responsive layouts, model routing, and core interaction paths.

  • Portfolio UX & Typography Passes

    Design-quality implementation and responsive polish

    Implemented advanced light/dark visual systems, accessibility improvements, and motion tuning with production-safe test coverage.

  • Promptfolio

    promptfolio.dev · 15+ Custom GPTs

    Independent, iteratively refined catalog of Custom GPTs — including a Prompt Engineer / Prompt QA / Red Team trio that applies review-and-adversarial-testing discipline to prompt design itself.
