My technical expertise centers on TypeScript, React, Next.js (App Router), Node.js, and cloud ecosystems like AWS and Vercel. I don’t just write code; I bridge the gap between engineering and business growth. I leverage modern AI-assisted engineering workflows (Claude Code, Cursor, Copilot, LLMs) to write, test, and deploy clean code up to 35% faster than traditional workflows, allowing me to solve complex technical challenges rapidly and independently. Core Technical Impact & Achievements: • Core Scalability: Optimized legacy microservices structures, reducing server response times and API latency by up to 42% in critical backend paths. • Frontend Performance: Improved frontend loading speeds by ~30% through SSR/ISR optimization, advanced rendering tuning, and Next.js/React performance best practices. • Architecture & UI Foundations: Built a custom React + TypeScript component library and design system that eliminated ~98% of UI inconsistencies in production within 6 weeks. • Code Reliability: Developed automated testing infrastructures from scratch using Jest, Cypress, and Playwright, achieving 85%+ test coverage and reducing production regressions by ~40%. Core Technical Toolkit: • Frontend: React, Next.js (App Router), TypeScript, Tailwind CSS, shadcn/ui, Zustand, GraphQL. • Backend & Databases: Node.js (Express), Python, PostgreSQL, MongoDB, Prisma, Redis. • Infrastructure & DevOps: AWS (S3, EC2, Lambda), Vercel, Docker, CI/CD pipelines, Git. • AI & Productivity: Claude Code, Claude 3.5, Cursor, GitHub Copilot. I operate with high autonomy, communicate directly with product stakeholders, flag blockers early, and take full ownership of production health. Let’s collaborate to build your product, fix critical bugs, or scale your platform efficiently. less -
