Currently contributing to the React Native mobile app experience at Cars24 (UAE).

Throughout my career, I have been recognized for my ability to translate complex requirements into user-friendly, impactful products. Notable achievements include a 40% boost in conversion rates by implementing a micro-frontend architecture, enhancing code quality through best practices like named arguments, and mentoring the next generation of developers. I am driven by curiosity and a relentless pursuit of growth, thriving in collaborative environments where cross-functional teams, designers, and product managers come together to create extraordinary products.
