I’m a Full Stack and Mobile App Developer with a strong foundation in C++, JavaScript, TypeScript, and Python, passionate about building scalable applications that solve real-world problems. I have hands-on experience developing dynamic web apps with React, Node.js, Express, and MongoDB, as well as crafting cross-platform mobile apps using React Native. My work spans from optimizing performance and UI/UX to integrating APIs and deploying applications on the cloud. I’m especially interested in AI-driven solutions and next-gen technologies, and I’m eager to contribute to teams that value innovation, creativity, and impact.

At DOJ App, I contribute to developing and optimizing both the Partner App and User App for a fast-scaling food delivery platform using React Native. My work focuses on performance, UI/UX, and seamless real-time interactions that directly impact customer experience and partner efficiency.
Optimized performance & UX: Migrated state management from Redux Saga to React Query, reducing API calls by 45%, cutting bundle size by 2.5MB, and improving data-fetching efficiency by 50%.
Improved Partner App workflows: Enhanced real-time order management by implementing custom notification sounds and deep linking, which boosted partner engagement and improved response times.
Redesigned cart & checkout flow: Re-architected the User App’s cart system with local state management, reducing cart-related API calls by 60% and increasing checkout completion rate by 25%.
Boosted scalability & reliability: Collaborated with backend teams to integrate secure APIs and optimize delivery operations for 100+ active delivery partners.
Optimized builds: Applied code-splitting, lazy loading, and asset optimization to shrink build size from 40MB to 33MB (17.5% reduction) and reduce initial load time by 25%.
Currently, I’m leading enhancements in the User App, focusing on delivering a faster, more intuitive experience for customers, while continuously improving scalability, real-time communication, and overall stability of the platform.
