About Narsingh
Full stack software engineer
Bengaluru, India - 8:48 am local time
I build scalable, reliable web applications end-to-end — from clean React.js front-ends to robust Java and Spring Boot back-ends. With 1.5+ years of hands-on engineering experience, I help businesses and startups turn ideas into working products that are fast, maintainable, and built to scale.
What I can do for you:
Full-stack web development (React.js, Java, Spring Boot, REST APIs)
Test automation with Selenium and Cucumber to keep your product bug-free
CI/CD setup and optimization (Jenkins) for faster, more reliable releases
Database design and back-end architecture
Why work with me:
End-to-end ownership - I handle front-end, back-end, and deployment so you don't need to juggle multiple developers
Clear communication and on-time delivery
Quality-first approach: clean code, proper testing, and documentation
Whether you need a new web app built from scratch, an existing product improved, or automated testing set up, I'd be glad to help. Let's discuss your project.
