At Invictron, I integrated BiTChat into a geospatial app using NASA WorldWind, enabling real-time in-app collaboration without switching to an external application.
At ChangePay, I developed secure signup and login with Node.js, Express.js, JWT, and bcrypt, and designed user-data schemas with Mongoose.
For my inflation forecasting project, I built models for India and Indonesia using machine-learning and time-series methods. The work achieved 94% forecasting accuracy.
On an e-commerce analytics project, I analyzed more than 100,000 transactional records, modeled churn risk and customer lifetime value, and built a Power BI dashboard. The churn model reached 88% precision in forecasting at-risk accounts.
