About Me

I am a results-driven software developer with strong experience in building, deploying, and maintaining production-ready web and mobile applications. I specialize in backend and full-stack development, with a growing focus on mobile solutions using Flutter.

I have worked across the full software development lifecycle — from requirements analysis and system design, to implementation, deployment, and post-release support. My experience includes developing scalable APIs, e-commerce platforms, mobile applications, and data-driven systems that solve real business problems.

I am comfortable working with modern development tools and infrastructure, including containerization, Linux-based servers, cloud deployments, and CI/CD workflows. I value clean code, system reliability, and continuous improvement, and I enjoy collaborating with cross-functional teams to deliver impactful solutions.

It will be my pleasure working with you.
