I'm Hong Kong based Senior Full Stack Engineer, 18+ years of experience, Top Rated Plus, 100% job success across all Upwork jobs. Before working as a freelancer I used to work for various multi-national corporations (BNP Paribas, Citibank, UniCredit, Astek, Prenetics, EPAM). I'm an AI Native engineer and deliver high-quality code in hours, not weeks. Proficient across the top AI coding tools - Claude Code, Cursor, Codex, OpenClaw, Hermes. I've built my own AI study platform and it's live in production. It uses AI agents to generate high-quality study materials based on content. I personally use this app to close my knowledge gaps when doing AI-driven development. The software development loop is simple - you deliver a feature fast, in several hours, then you close the knowledge gaps that it created, then continue. I work hands-on coding every day. React and Next.js on the frontend, Node.js (Fastify, NestJS, Express) on the backend, PostgreSQL or Supabase on the data side. AWS for production infra (Lambda, ECS/Fargate, CDK, Cognito, EventBridge, SNS/SQS). I implemented world-class event-driven infrastructure on AWS for startup projects in days. I've implemented my own version of Leetcode in just one day using event-driven highly scalable architecture. I also ship production mobile apps with React Native and Expo (EAS Build/Update, App Store and Google Play submission). Several of my recent Upwork jobs have included Technical Lead delivery on small product teams: backlog refinement, sprint planning, user stories and estimation, architecture decisions, code review and unblocking the team, while I still ship features myself across the stack.
