• Designed and built a full-stack e-commerce platform end-to-end: NestJS REST API, PostgreSQL schema and migrations, Redis caching, Next.js 15 / React 19 storefront, and a React Native mobile client in a Turborepo monorepo. • Architected a provider-agnostic payments layer over Stripe with entitlements resolved in the database, allowing the payment processor to be swapped through configuration rather than code changes. • Integrated automated print-on-demand fulfillment with two third-party vendor APIs, handling asynchronous order state, retries, and reconciliation across systems outside my control. • Authored and published two open-source TypeScript SDKs to npm (Printify and Prodigi print APIs) after finding vendor-supplied clients insufficiently typed for production use. • Built a two-stage LLM pipeline for automated product description generation and an MCP server exposing the product catalog to AI agents. • Developed a reusable canvas-based design editor (Fabric.js) published as an npm package, supporting layers, undo/redo, cropping, snapping, and multi-format export.

Top performer on LoanOfficer One, an internal Vue/TypeScript platform of several hundred screens serving 3,500+ loan officers nationwide at the #1 US retail mortgage lender, deploying weekly. • Achieved a 3x improvement in application load time through performance profiling and targeted optimization of the table rendering path. • Designed and implemented the frontend architecture for Cube, a configurable analytics interface for querying loan and user datasets, and one of the platform’s largest features; defined the API interface contract jointly with backend developers. • Added full TypeScript coverage to the networking/API subsystem, eliminating a class of runtime errors caused by type mismatches and enabling reliable AI-assisted development. • Implemented optimistic updates, request debouncing, and response caching in the shared networking layer, cutting redundant network traffic and improving interaction responsiveness up to 2x in the heaviest workflows. • Championed AI-assisted engineering workflows (GitHub Copilot with Claude, Codex), integrating automated code review, test generation, and documentation into the development process and improving delivery speed up to 2x. • Extracted shared components into a Storybook component library (configurable table, column selector, drag-and-drop tree view), adopted across multiple company projects. • Established lint rules and architecture guidelines through cross-team consensus, encoding standards as automated tooling rather than manual review. • Built end-to-end test coverage with Playwright and unit tests with Jest; partnered with tech support and backend teams to diagnose production incidents, eliminating recurring race conditions in parallel API call queues and stabilizing critical workflows.
