What I'm looking for

I am looking for a challenging role that fosters innovation and collaboration, where I can leverage my skills in full-stack development and contribute to impactful projects.

I am a seasoned Java Full-Stack Developer with over 6 years of experience in designing and developing scalable web and mobile applications. My expertise lies in utilizing Java (Spring Boot), Kotlin, and Python for backend services, while employing React, Vue.js, Angular, and Flutter for responsive front-end development. I have a proven track record of building secure APIs and implementing CI/CD pipelines, ensuring high-quality software delivery.

Throughout my career, I have engineered enterprise-grade digital banking applications, developed RESTful APIs, and optimized data pipelines for real-time analytics. I have successfully integrated payment gateways and AI-powered features into applications, enhancing user experience and operational efficiency. My commitment to best practices in software development, including Test-Driven Development (TDD) and Behavior-Driven Development (BDD), has consistently resulted in high test coverage and reduced production defects.
