At MedPlus Health Services Limited, I modernized the Purchase Management System from Java 8 to Java 21 and Spring Boot 3.3.8, with a React 18 frontend. I also authored a reusable Excel processing engine for 15+ domain schemas.
I built an automated procurement decision engine that evaluates stock, sales demand, and discount tiers to project profitability, with approval workflows and purchase order generation.
I built an event-driven GST and e-invoice processing pipeline handling 195M+ records, using Spring WebFlux and ActiveMQ. I also implemented Redis-backed token caching to help prevent government API rate-limiting and thread exhaustion during peak traffic.
For field operations, I designed a cross-platform React Native and TypeScript warehouse logistics app with offline package scanning and real-time geolocation tracking. I also introduced SonarQube quality gates and distributed tracing to support quality checks and system-wide debugging.
