At KARBAN ENVIROTECH PRIVATE LIMITED, I built and maintain the Karban IoT app for iOS and Android, used by 500+ customers to control their air purifiers, fans, and lights. I implemented real-time device control over MQTT and local WebSockets, along with OTA firmware updates and device sharing.
I also built the app’s serverless backend on AWS Lambda with custom Cognito authentication, and integrated Alexa and Google Home using OAuth 2.0 account linking. For the company’s sales team, I designed and built a role-based platform that replaced spreadsheet-based order handling.
At GRABTHESITE, I built the frontend of a law-firm case management platform, including admin and lawyer views, a hearings calendar, and legal document generation. I integrated REST APIs and used pagination, debouncing, code splitting, and memoization to keep large case lists responsive.
In my projects, I implemented a delivery ETA prediction model from scratch and served it through a FastAPI endpoint. I also built QueueForge, a distributed job-processing platform with scalable workers and a React dashboard.
