I build scalable products that solve real business problems.
I’m a Full Stack Developer with 1.5+ years of experience building real-world, production-grade applicationsI work across the stack using React, Next.js, Node.js, and TypeScript turning ideas into fast, reliable, and user-friendly products.
At Europass Immigration, I’ve developed a full-stack CRM system, automated business workflows, and built a company-facing platform with secure authentication and real-time features. My focus is not just on writing code, but on building systems that are scalable, maintainable, and solve actual user problems.
I enjoy working at the intersection of clean UI and solid backend architecture — designing intuitive interfaces while ensuring the underlying systems are efficient and robust. Currently, I’m exploring ways to build better SaaS products and improve performance in modern web applications.
