I’m a Senior Software Engineer with 4.5+ years of experience building scalable Java backend and full-stack applications, primarily in the FinTech domain. At Mintoak, I work on enterprise merchant onboarding and digital payment platforms used by leading banking partners including HDFC Bank, SBI, Axis Bank and ABSA. My day-to-day work involves designing microservices, developing secure RESTful APIs, optimizing backend performance and building cloud-ready applications that are reliable, scalable and easy to maintain. My core technical expertise includes: • Java 17 • Spring Boot & Spring Security • Microservices • React.js • Apache Kafka • Redis • PostgreSQL • AWS • Docker & Jenkins Over the last few years, I've worked extensively on event-driven systems, distributed caching, API security, database optimization and real-time device connectivity using MQTT and EMQX. I also enjoy building reusable developer tools, which led me to create ZeroMapper - an open-source Java object mapping library. I'm passionate about writing clean, maintainable code, solving complex backend engineering problems and continuously learning modern software architecture and cloud technologies. I'm always happy to connect with fellow engineers, hiring managers and recruiters working on Java, Spring Boot, AWS, Microservices and distributed systems.
