About

I'm a backend-focused software engineer and Technical Lead at HCLTech, building scalable microservices, high-reliability REST APIs, and production-grade distributed systems using Java and Spring Boot. In less than a year at HCLTech, I've driven measurable impact: Boosted system reliability by 40% through modular Spring Boot microservices Reduced production defects by 30% by resolving 100+ critical incidents Elevated code coverage from 45% to 92% while fixing 700+ SonarQube issues Accelerated deployment cycles by optimizing CI/CD pipelines and Git workflows Before joining HCLTech, I served as a Student Entrepreneur-in-Residence at IIIT Delhi Innovation & Incubation Center, where I launched CraftBox — an operational commerce platform with 50+ active users, 100+ product-vendor-order schemas, and real-world transaction workflows built on MERN stack and MongoDB. Competitive Highlights: AIR 1 — Smart India Hackathon 2024 (Hardware) | 1st among 300,000+ participants AIR 1 — Clash of Codes by Microsoft | 1st among 400 teams Top 100 — Amazon ML Challenge | Top 0.1% among 72,000+ participants AIR 2 — ACM HackData | 2nd among 750+ teams Technical Stack: Languages: Java, Python, SQL Backend: Spring Boot, Microservices, REST APIs, JUnit, Selenium (BDD) Frontend: Angular, React, React Native DevOps & Cloud: Docker, Git, CI/CD, AWS, Linux AI/ML: TensorFlow, OpenCV, Scikit-learn, Pandas, NumPy Databases: PostgreSQL, MongoDB, MySQL What drives me: I enjoy solving complex engineering problems at the intersection of backend architecture, AI, and real-world product development. From architecting multi-vendor marketplaces and hyperlocal delivery systems to building enterprise-grade banking platforms, I focus on ownership, scalable design, and execution quality. Open to discussions around distributed systems, backend engineering, AI-driven products, and startup ideas. Contact: prince21182@iiitd.ac.in Portfolio: https://celadon-entremet-98ce12.netlify.app
