Hello, I'm Neelesh Janga.
Software Engineer
I am building cloud-native solutions by modernizing legacy systems using technologies like Spring Boot, gRPC, RabbitMQ, Redis, and containerized deployments.
About Me
I’m a Software Engineer with a strong focus on backend development, microservices architecture, and secure, scalable enterprise applications. At Peer Islands, I contribute to modernizing legacy systems and building cloud-native solutions using technologies like Spring Boot, gRPC, RabbitMQ, Redis, and containerized deployments.
With a passion for clean code, performance optimization, and secure development practices, I work closely with cross-functional teams to deliver high-quality software that meets business goals. I’m experienced in writing robust code for feature developments, resolving complex technical issues and bugs, and ensuring compliance with security and quality standards.
Previously, I worked at ValueLabs, where I was recognized for my contributions to client-facing projects and awarded multiple times for excellence and innovation. I’m always eager to learn, adapt, and grow—whether it’s exploring new technologies, improving system design, or mentoring peers.
