Selected work

Recent work at Capital One, shared without internal details. Each entry says exactly what my part was.

My part: Led full-stack integration
Stack: LLM integration, React, Node.js

AI message assistant

Live in production with real users.

An AI assistant that checks messages for mistakes and sensitive details before they go out. I built the review experience that keeps a person in the loop, plus the APIs and data behind it.

My part: Co-built
Stack: Claude, TypeScript, Prompt design

Preference-aware chat prototype

Built for a hackathon.

A Claude prototype that picks up preferences from conversation and asks the follow-up a good person would. Mention seafood, and it asks what kind.

My part: Led
Stack: Node.js, React, AWS

Sign-in reliability

Far fewer people signed out mid-task.

People were getting signed out in the middle of their work. I tracked down why and fixed it.

My part: Delivered
Stack: TypeScript, React

Build migration

Builds from minutes to seconds.

Compared the modern build tools, picked one, and moved a large React app over to it, tidying up the TypeScript setup on the way.

My part: Led
Stack: Claude Code, React

React upgrade with coding agents

A full React upgrade, every test passing.

Ran the big refactors with Claude Code agents and kept the test suite green the whole way.

What I work on

The work I like most: AI in a real product, not a demo.

LLM features in real products: Adding AI to apps that already have users: the model calls, the APIs around them, and the interface people actually touch.
Guardrails and human review: Checks that catch bad or sensitive output before it ships, plus review flows that keep a person in control.
Agentic coding workflows: Setting up Claude Code and similar agents for large refactors and upgrades, with tests that prove nothing broke.
Front-end modernization: React upgrades, editor migrations, and build tooling that turns minutes into seconds.
