Delivered a developer tool launch page with GSAP animations, custom typewriter reveal, SVG scroll transitions, and a video loading system. Built AI-powered chat interfaces with streaming APIs (SSE and WebSocket) for client engagements, including token-by-token rendering and image-generation integrations. Built full-stack features for clients: REST APIs in Python and Node.js, schema design across PostgreSQL/MongoDB, and integrated React frontends. Shipped production frontends end-to-end with ownership of scope, architecture, performance tuning, and post-launch handoff.

Architected a 40+ component React/TypeScript library with Storybook, standardizing UI across multiple product surfaces. Built Python backend services and REST APIs powering features, with PostgreSQL data models and MongoDB for document-heavy workloads. Implemented Zustand and React Query for state management, reducing API calls by 35% on high-traffic flows. Led code reviews, established ESLint rules, and mentored 3 junior developers.

Delivered production web applications for 50+ client engagements across B2B SaaS, fintech, and AI tooling. Owned end-to-end scope: architecture, implementation, testing, and delivery. Built TypeScript/React frontends and backend services in Go, Node.js, and Python; designed REST, WebSocket, and SSE integrations for real-time and high-throughput workloads. Developed AI-powered workflows with server-side schema validation, deterministic mock modes for CI, eval/regression fixtures, and persistence plus audit/history layers. Used modern AI coding assistants to accelerate work while reviewing, testing, debugging, and ensuring I retained ownership of generated changes prior to integration. Produced documentation including architecture notes, setup/deployment instructions, and handoff materials for maintainability.
