What I'm looking for

I seek a role that fosters innovation, collaboration, and continuous learning in a dynamic environment. With over 20 years of experience in engineering leadership and scalable architecture, I’ve built systems serving millions and led high-performing teams across cloud-native and SaaS platforms.

I am a seasoned Delivery Leader and Enterprise Architect with over 20 years of experience in designing and implementing scalable, high-performance solutions across various industries. My journey began with a Bachelor of Engineering in Computer Science, and I have since honed my skills in cloud architecture, microservices, and agile methodologies. Currently, I lead India Operations at Kukun, where I spearhead the development of a microservices-based backend platform, optimising costs and enhancing user engagement.

Throughout my career, I have successfully directed cross-functional teams, mentored engineers, and driven significant cost optimisations in cloud utilisation. My expertise spans multiple technologies, including Java, Spring Boot, and various database systems, enabling me to architect solutions that not only meet business needs but also foster innovation. I am passionate about leveraging technology to solve complex problems and deliver value to clients.
