I will build secure web applications
Gokilavani M
About this gig
Need a complete web application built right secure backend, modern
frontend, all working together? I build full stack applications using
Spring Boot and React.js, backed by 3 years of production experience
in fintech and government SaaS platforms.
What I deliver:
- Spring Boot REST APIs & microservices
- React.js frontend responsive and clean
- JWT authentication, RBAC & secure user management
- MySQL database design and query optimization
- Payment gateway integration with transaction safety
- Redis caching for performance
- API documentation (Swagger/OpenAPI)
- Unit & integration testing (JUnit 5, Mockito)
Proven results from real production work:
35% reduction in API latency
Supported 5,000+ daily active users at 99.9% uptime
Report generation cut from 8s to 1.8s
I don't just connect a frontend to a backend I build systems that
are secure, fast, and maintainable, the same way I build them in
production.
Message me with your project details before ordering. I'll confirm
scope, timeline, and any custom needs so there are no surprises.
Let's build your application right, from database to browser.

FAQ
What information do you need to get started?
Your project requirements, any design references or wireframes if available, and preferred tech stack details (e.g., specific database, hosting platform). I'll confirm scope before starting.
Can you work with my existing codebase instead of building from scratch?
Yes — I can review, extend, or refactor an existing Spring Boot or React project. Share the repo or files after we connect.
Do you handle deployment/hosting?
Yes — full source code, Swagger/OpenAPI documentation, and a README are included in every package.
What if my project doesn't fit neatly into these packages?
Message me with your requirements first. I'll suggest a custom scope and quote rather than forcing it into a package that doesn't fit.
How fast do you respond to messages?
I typically respond within a few hours on weekdays. I work part-time as a freelancer alongside a full-time role, so I'm upfront about realistic delivery timelines rather than promising instant turnaround.
