Building production web applications is easy. Building ones that stay stable at scale, handle real users, and don't require constant babysitting — that's a different problem. That's what I focus on. I'm a full-stack developer based in Seoul with 3+ years building web platforms for international teams. My stack: React / Next.js on the frontend, NestJS / Node.js on the backend, PostgreSQL and MongoDB for data, Docker + AWS for deployment. Recent work: • Built a client management platform for a 4-country consulting firm — 40+ REST API endpoints, real-time Socket .io messaging, JWT auth with role-based access control, Docker / Nginx deployment with zero-downtime releases • Developed a product catalog and inventory system for a 2,000+ SKU electronics retailer — MongoDB aggregation pipelines cut query times by 60%, AWS EC2/S3 infrastructure I also integrate AI into web apps — OpenAI API, LangChain, Groq — for features like intelligent search, automated workflows, and AI-powered assistants. This is increasingly what clients need and where I spend a growing part of my time. What I build well: → Full-stack SaaS and business platforms → REST API backends with auth, RBAC, and real-time features → AI-powered features integrated into existing or new web apps → Automated workflows (n8n + custom integrations) → Production deployments — Docker, AWS, Nginx, CI/CD I communicate clearly, push updates regularly, and treat your deadline as my deadline. If your project needs a developer who can own the whole stack — from database schema to deployed UI — let's talk.

Full-stack developer specializing in building scalable web, mobile, and backend systems. I have led the migration of an Expo-based mobile application to pure React Native, restructuring native modules and stabilizing the iOS/Android build environment. My expertise includes React Native, Next.js, and NestJS, with hands-on experience in AWS infrastructure, CI/CD automation (GitHub Actions, App Store Connect API, Firebase App Distribution), and database optimization (PostgreSQL/MySQL). I focus on system stability, performance optimization, and maintainable architecture — including large-scale data migration (JSON → SQLite with indexing), runtime monitoring, and automated deployment pipelines.
