What I'm looking for

I am looking for opportunities that foster innovation, collaboration, and career growth in a dynamic environment.

With over 14 years of professional experience, I am a Senior Software Engineer dedicated to delivering highly scalable and visually engaging web applications. My expertise lies in modern JavaScript frameworks such as React.js, Next.js, and TypeScript, enabling me to create real-time dashboards and SaaS platforms that enhance operational efficiency. I have successfully collaborated with global clients, including BP and Chevron, to develop solutions that significantly improve data integrity and reduce financial risks.

Throughout my career, I have demonstrated a strong ability to optimize backend microservices and implement cloud-native architectures using AWS and Azure. My work has consistently resulted in improved performance metrics, such as a 60% reduction in API response times and achieving 99.99% uptime for deployed services. I thrive in cross-functional teams and am passionate about leveraging technology to solve complex challenges in the financial technology and energy sectors.
