Hi, I’m Kevin Tan, a senior full-stack developer with 8+ years of experience building secure, scalable web applications across modern frontend and cloud-based backend systems. I specialize in React/Next.js and TypeScript, with hands-on API development in Node.js and Python (FastAPI/Django). I’ve designed AWS serverless architectures, implemented robust authentication (JWT/OAuth2), and championed DevOps practices like CI/CD and containerized deployments. I’m passionate about clean code, security best practices, and delivering high-quality digital products in agile environments. I enjoy collaborating with product, design, and QA to break down complex requirements into reliable, production-ready features, and I continually look for ways to improve performance, reliability, and engineering velocity.
