About

Professional summary

I am a Tech Lead and Full-Stack Web Developer specializing in React, Next.js, Node.js, TypeScript, and scalable web application development. I build performant, user-focused products across frontend and backend systems.

I lead development teams through sprint planning, task management, pull-request reviews, architecture decisions, and mentoring. I have managed a three-member team, reviewed more than 20 pull requests weekly, and helped improve feature delivery efficiency.

I have hands-on experience designing responsive interfaces with React, Next.js, Tailwind CSS, ShadCN, Styled Components, and Framer Motion. I create reusable UI components, analytics dashboards, and intuitive product experiences.

On the backend, I develop REST APIs and secure application services using Node.js, Express.js, NestJS, Prisma, MongoDB, and PostgreSQL. I also work with authentication, JWT, cloud storage, payment integrations, and subscription workflows.

I have delivered solutions including AI-powered posture analysis, automated Binance P2P profile operations, no-code visual editors, secure file-upload systems, and subscription platforms. I focus on performance, stability, maintainability, and measurable improvements in product delivery.
