Experience

01 — 2020 to present

I started in frontend and moved toward AI without leaving the interface behind. Each marker is coloured by the discipline the role actually leaned on.

Celnet

Senior AI Full Stack EngineerAlpharetta, GA

Architected an enterprise bid intelligence platform on LangGraph (structured tool calling, retrieval, business-rule validation, stateful orchestration), then built the React interface where users review and intervene at the decisions that matter. Bid opportunity intake improved 10–12%.

xAI

AI Engineer, LLM EvaluationSeattle, WA

Evaluated model behaviour across long multi-turn conversations and built the datasets and frameworks to measure grounding, hallucination, and task completion. Also built an agentic incident-response platform for security operations end to end (FastAPI services and React interface), processing incidents roughly 20% faster.

Washington State University

Full Stack Engineer, AI & AnalyticsPullman, WA

Built client-facing analytics interfaces in React and the Python microservices behind them: interactive data views over AI-generated output, wired to FastAPI through asynchronous retrieval. Also built NLP preprocessing pipelines covering tokenization, normalization, and feature extraction, with structured logging and fault-tolerant processing throughout.

Deloitte

Software Engineer, Full Stack (B2B)India

Turned Figma wireframes into production B2B interfaces across multiple modules in React and TypeScript, built on reusable component patterns and integrated with REST APIs through async workflows. Improved application responsiveness by roughly 10% through lazy loading, code splitting, and caching, with Cypress coverage over the critical paths.

How I work

03 — Four convictions
Grounding

Show the sources, not just the answer

A confident paragraph with nothing behind it is worse than no answer at all. Citations belong in the default view, not behind a disclosure arrow.

Human-in-the-loop

Put the person at the irreversible step

Automation should run freely right up to the point where a mistake costs something. That is where the interface stops and asks.

Failure design

Design the failure path first

Ambiguous intent, lost context, a tool that times out. These are the common cases, not the edge cases, and they deserve real screens.

State

A conversation is state, not a transcript

What the agent knows, what it assumed, and what it is waiting on should all be visible. If a user can see the state, they can correct it.

Capabilities

About

05 — The short version

I spent my first years building interfaces and my last few building the systems behind them. That combination is the whole point: I can argue about retrieval strategy in the morning and about where a confirmation dialog belongs in the afternoon, and I think those are the same argument.

Most of my work now lives in regulated, high-stakes workflows (bids, contracts, legal documents) where an AI system has to be transparent enough that a person will actually sign off on what it produced. Making that legible is a design problem at least as much as an engineering one.

Outside of work I love to sing, write songs, dance, and play badminton!

Would love to work on building more impactful AI-powered Applications

If you are building something where people and agents have to work together, I would like to know more about it.
