What I'm looking for

I’m looking for a full-stack developer role where I can build impactful web and mobile apps using React, React Native, TypeScript, and Node.js. I enjoy solving complex problems, optimizing performance, and creating polished, scalable solutions. I value collaboration, innovation, and long-term growth opportunities.

I’m a full-stack developer focused on building practical, high-quality digital products that solve real problems.
I work across the stack with modern frontend frameworks and robust backend technologies to deliver dependable user experiences.
I’ve delivered marketplaces, dashboards, eCommerce platforms, and real-time applications, emphasizing performance, reliability, and responsive design.
I built a scalable operations dashboard supporting 5,000+ active users and improved page load times by 50%.
My backend experience spans Node.js, PHP (Laravel), and Python (FastAPI, Flask), and I’m comfortable with MySQL, PostgreSQL, and MongoDB.
I use Docker, AWS, and CI/CD pipelines to make deployment fast and dependable.
I’ve led architecture and migration efforts—from monolith to microservices—improving reliability and reducing costs, and I’ve implemented automated testing and reusable component libraries to increase development velocity and reduce defects.
