About

I’m a Senior Full-Stack Developer with over 10 years of experience building reliable and scalable web applications for businesses and startups. I specialize in React, Next.js, Node.js, TypeScript, Python, and Go — creating high-performance front-end interfaces and secure back-end systems. I’ve delivered SaaS platforms, dashboards, and API-based services that handle large volumes of data and transactions. My focus is on clean architecture, maintainable code, and business-ready performance. I collaborate closely with teams to turn complex ideas into efficient, production-quality software. In addition to full-stack development, I also have expertise in blockchain integration — connecting modern web apps with smart contracts and decentralized systems when needed. If you need a dependable developer who understands both technical depth and business goals, let’s connect and discuss your project.
