Full-stack software engineer with 11 years of professional experience. Frontend at federal scale in React and TypeScript, backend in Node.js and NestJS on AWS (Fargate, RDS PostgreSQL, Lambda, API Gateway, DynamoDB, AppSync, CDK), and native mobile in React Native. Takes products from data model to interaction: API design, infrastructure as code, and the UI users actually touch. Ships applied AI features (agent orchestration, retrieval, and evals) in open source, and codes AI-augmented daily on Claude Code with a spec-driven workflow. Leads teams and mentors engineers; a background in cultural anthropology sharpens the read on the gap between what users actually do and what the spec describes.

Senior Solution Specialist (Senior Full-Stack Software Engineer)
Jun 2021 – Present
Hybrid, Gilbert and Tempe, AZ
Lead senior engineer on PoolRM, an internal firm staffing-intelligence platform (~300 weekly users) matching project needs to consultant availability and skills. Designed and built the backend, a NestJS + Node.js API on AWS Fargate with RDS PostgreSQL, provisioned via AWS CDK, using Prisma and Zod across an npm-workspaces monorepo. Authored a cross-compatible Claude Code + Copilot AI-context system for uniform coding quality across machines and sessions, and introduced PRD-driven, BMAD-influenced AI development.
Led a 15-developer offshore team on the React frontend for Michigan's unemployment insurance modernization (2,000+ pages, 270K residents) on Deloitte's LIFT framework. Personally drove WCAG 2.1 AA conformance and a sidebar performance overhaul, custom ms-precision metrics, O(n²) -> O(n), context-state caching for permissions, averaging 30% improvement.
Modernized the tax-payment UX for 880.9M annual visits and $4.7T in FY2023 federal collection by leading the ReactJS + TypeScript frontend rebuild and shipping every release through the U.S. Treasury release train at production scale.
Cut bank onboarding from 60 days to 7 days for 1,000+ participating banks by serving as sole frontend on the LWC/Salesforce app and co-locating with the Federal Reserve's Boston-based team at the Deloitte lower-Manhattan office 4–5 trips per year over 2 years. Ran PI / release planning and requirements refinement in-person with the client's PM and scrum master, and mentored their backend Apex engineers on frontend during contract handoff.
Served as paired coach for 7 new-hire developers (junior and mid-level consultants) and informally mentored dozens more.
