I work across the whole stack — React and TypeScript on top, Spring Boot and AWS underneath — and build the AI tooling that gets it shipped faster.

Four years, 10+ production features, 100k+ monthly users — currently at JPMorgan Chase. I designed the UI and built the API and graph layer for Cobol Studio, a patent-pending tool that maps decades-old mainframe code into a graph database and uses AI to explain it in plain language, now used by 500+ employees.

The AI agent skills I've written are now part of how my team ships — scaffolding a repo end to end (platform, pipeline, and test setup), reviewing PRs against our own engineering standards, and generating Jest and Playwright suites that cover accessibility, not just the happy path.

Experience

2023 - now

  1. JPMorgan Chase

    2024 - now

    Software engineer II · consumer credit · Wilmington, DE

    • Ship the credit line increase and exchange, plus balance transfer flows — the decisioning behind them clears $1.3B+ annually at 99.9% uptime.
    • Rewrote the servicing front end from legacy JavaScript into React and TypeScript: 40% faster page loads on a 25% smaller bundle.
    • Built the internal tool agents use to correct customer data — turnaround down from 24 hours to 5 minutes.

  2. Donovan

    2023 - 2024

    Full-stack engineer · early stage · remote

    • Built the learning platform behind a music and art program for underserved kids — animation-heavy Next.js, server-rendered for 40% more organic reach.
    • Fenced student records behind row-level security in Supabase, enforced at the database rather than the API.

  3. SUNY Research Foundation

    2023

    Software engineer · assistive tech research · Buffalo, NY

    • Built speech-to-text and text-to-speech keyboards for people with ALS, cerebral palsy, and autism.
    • Built the tool researchers use to capture and score responses in an augmentative communication study — Flask APIs on Docker, 50% more concurrent sessions, $50K a year saved.
