About Me
I’m a full-stack developer focused on building scalable web applications with React, Next.js, TypeScript, and modern backend systems. Currently, I'm working on enterprise Java Spring Boot applications, building and maintaining backend services used in large-scale insurance workflows. I enjoy understanding how things work under the hood — not just writing features, but improving architecture, performance, and developer experience.
Current Advanture
Most of my recent curiosity has shifted beyond frontend development into networking, self-hosting, and infrastructure. I've been experimenting with home lab setups, running services like Pi-hole, learning networking fundamentals, and exploring how systems communicate at a lower level. Alongside backend development with Spring Boot, I enjoy debugging tricky issues, understanding system behavior, and learning how large-scale applications are designed and operated.
TL;DR:
Software Engineer at TCS with 2.3 years of experience building enterprise applications using Java, Spring Boot, React, and TypeScript. Passionate about backend engineering, system architecture, and home lab projects with Raspberry Pi. Also enjoy playing chess and exploring new technologies.

Legacy Mainframe Modernization Platform
→ Deliverable:
Modernized enterprise securities processing workflows by migrating 40+ COBOL/CICS programs into Java 21 and Spring Boot REST APIs while preserving legacy transactional behavior for critical backend systems.
→ Tools & Technologies Used:
→ Performance Improvements:
Designed a custom CICS transaction emulation framework using Spring AOP and ThreadLocal to minimize business logic rewrites during migration. Built asynchronous processing workflows using @Async and ThreadPoolTaskExecutor to improve scalability and reduce blocking operations. Enhanced production reliability through centralized exception handling, correlation logging, Oracle query optimization, and HikariCP connection pool tuning across multi-environment deployments.
→ Impact:
Accelerated legacy modernization initiatives by enabling scalable Java-based transaction processing, improving backend throughput, standardizing CI/CD pipelines, and increasing deployment reliability across DEV, TEST, QA, and PROD environments.
Insurance Portal
→ Deliverable:
Migrated a legacy Angular + Java Spring Boot application to a React-Redux + Java Spring Boot architecture with optimized performance and maintainability.
→ Tools & Technologies Used:
→ Performance Improvements:
Optimized state management with Redux, enhanced Spring Boot API integrations, reduced response time, improved data retrieval efficiency, and increased application scalability.
→ Impact:
Achieved 30-50% faster UI rendering and 20-40% improved API response times after migration from legacy Angular to React.
Wealth Management Portal
→ Deliverable:
