## About

I’m a Software Development Engineer with experience building scalable systems, real\-time applications, and high\-performance user experiences across ed\-tech, logistics, and SaaS platforms\. I specialize in full\-stack development, distributed systems, real\-time communication, and performance optimization\. At Yocket, I work on GMAT & GRE prep features powering thousands of learners—video lessons, full\-length mock tests, personalized study planners, adaptive practice algorithms, and content recommendation systems\. I build scalable backend workflows with Node\.js, Redis, PostgreSQL, MongoDB and high\-performance interfaces using Nuxt 3, Next\.js, Zustand, and TailwindCSS\. Previously at iNeuron\.ai, I developed high\-concurrency systems using Redis clusters, AWS queues, cron pipelines, and complex MongoDB analytics\. I also designed maintainable backend architectures with high test coverage using Jest\. At Roado, I worked on logistics and navigation solutions by integrating Google Maps & GPS, improving UI performance with TailwindCSS, optimizing Lighthouse scores, and streamlining data flows using GraphQL, RabbitMQ, Redux, and React Query\. I enjoy building real\-time products—whether it’s chat systems, compilers, or collaborative tools\. Some of my projects include Support System, a real\-time AI\-assisted doubt\-resolution platform, and Codezen, an online compiler with real\-time code sharing and WebRTC support\.
