Projects

TEJA OS — AI-Powered Digital Twin Platform for EHV 400/220kV Substations

REST API, React

Engineered a digital-twin monitoring system for EHV substations that ingests real-time telemetry and renders live equipment state through a scalable REST API backend and React dashboard.
AYAN OS — AI-Powered Smart Railway Traffic Control & Digital Twin Platform

Node.js, Express, React, React Three Fiber

Architected a digital-twin platform simulating train movements in real time, decoupling a Node.js/Express backend from a React + React Three Fiber 3D frontend. Designed scheduling and conflict-resolution logic and surfaced AI-assisted decision support through REST APIs.
CausaPay — Causal Intelligence for Incremental Payment Recovery

Python, FastAPI, React, TypeScript, Vite

Built a doubly-robust causal inference system (AIPW) to estimate incremental payment recovery under confounded treatment assignment. Modeled counterfactual outcomes, benchmarked against baselines, and improved CATE MAE as training data scaled.
BajriX — Marketplace Backend

Java, Spring Boot, PostgreSQL, JPA/Hibernate, Maven, Flyway

Built a marketplace backend in Java and Spring Boot with PostgreSQL, exposing REST APIs for product, seller, and listing management backed by Spring Data JPA/Hibernate. Enforced data integrity with Jakarta Bean Validation, seller-status authorization, duplicate-listing prevention, optimistic locking, JPQL JOIN FETCH queries, Flyway-managed schema migrations, and integration tests.
