Work Experience

Product Developer

DigiValet

Apr 2026 - Present

Architected and deployed scalable backend services using Core Java and Spring Boot for smart automation, healthcare, and hospitality platforms, integrating hardware and enterprise systems via 10+ protocols like MQTT, RS232, KNX, HL7 etc. Optimized device integration workflows, protocol handling, and backend performance to improve interoperability, reduce API response times, and ensure reliable real-time communication across heterogeneous systems. Spearheaded end-to-end feature development and production releases within a large codebase, delivering optimized, maintainable solutions with 40% fewer post-release issues reported. Resolved critical production issues through debugging, root-cause analysis, and collaboration with QA, mobile, and hardware teams, improving system reliability and reducing deployment turnaround time by 40%. Guided peers on product use cases, coding standards, debugging methodologies, design patterns, and modular development practices while creating technical documentation, UML diagrams, integration flows, and troubleshooting guides to streamline onboarding and development by 30%. Applied clean coding principles, secure coding practices, consistent naming conventions, and optimization techniques to improve scalability, maintainability, and time/space efficiency across shared modules.
