About

I am a full-stack developer and software engineer with experience building web, mobile, and enterprise applications. I enjoy turning business requirements into practical, reliable products using technologies such as React, TypeScript, JavaScript, Java, Kotlin, Django, Node.js, MongoDB, SQL, and Spring Boot. My experience includes developing customer-facing platforms, RESTful APIs, mobile applications, CI/CD pipelines, and secure systems while following Agile, TDD, MVVM, clean architecture, and SOLID principles.

I am also comfortable supporting end users, troubleshooting hardware and software, maintaining systems, and collaborating with technical and non-technical stakeholders. I take pride in writing maintainable code, improving application performance and reliability, and working closely with designers and business teams to deliver user-friendly solutions. I am friendly, adaptable, and motivated by opportunities to solve problems and contribute to meaningful technology projects.
