What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth opportunities.

I am a Full Stack Engineer with over 10 years of experience in delivering scalable and responsive SaaS platforms and microservices. My expertise lies in utilizing technologies such as C# (.NET), Python, Java (Spring Boot), React, Vue, Svelte, and TypeScript to build cloud-native applications across Azure and AWS. I have a proven track record of integrating AI/ML models and driving high-performance user interfaces, ensuring accessibility and responsiveness across devices.

Throughout my career, I have successfully architected and deployed microservices, implemented robust CI/CD pipelines, and developed intelligent microservices that process high-throughput data streams. I take pride in mentoring junior developers and fostering a collaborative team environment, which has led to improved team velocity and reduced onboarding time. My commitment to delivering secure, data-intensive solutions has been evident in my work across fintech, edtech, and analytics-driven environments.
