Project details

I provide professional Java backend and frontend bug fixing services for web applications, APIs, and enterprise systems. If you’re facing errors, crashes, performance issues, or unexpected behavior in your Java or frontend code, I can quickly identify the root cause and deliver clean, reliable fixes.

I work with Java, Spring Boot, REST APIs, and frontend technologies like HTML, CSS, JavaScript, and React. My approach focuses on proper debugging, clean implementation, and long-term stability rather than quick hacks. Whether it’s API failures, backend logic bugs, UI issues, or integration problems, I ensure the fix is safe, tested, and maintainable.

You’ll get clear communication, structured debugging, and transparent delivery. I also provide explanations of the fix so you understand what was changed and why. This service is ideal for startups, businesses, and teams needing quick and dependable technical support without long-term commitments.

If you need reliable bug fixing and ongoing backend/frontend support, I’m ready to help.

About Soniya

Soniya V.Status: Offline
Java & Spring Boot Developer | React, Next.js & AI Integration
5.0  (1 review)
Gurugram, India - 4:47 am local time
Need a backend developer who can build secure, scalable APIs — and integrate AI into them — while actually understanding the business behind the product? That's exactly what I do.

I'm a Senior Software Engineer at Optum (UnitedHealth Group), building enterprise healthcare applications with Java, Spring Boot, microservices, REST APIs, React, Next.js and AI integration. With 5+ years of production experience — including 4 years at Optum, one of the world's largest healthtech companies, and a year at Apisero in enterprise consulting — I know how to ship reliable systems that handle real scale, security, and users.

What I bring to your project:
- Backend: Java, Spring Boot, Spring Security, Microservices, REST APIs, Hibernate, JWT, Node.js
- Frontend: React.js & Next.js for fast, responsive, SEO-friendly interfaces
- AI integration: LLM features with the OpenAI & Claude APIs, RAG, and automations / AI agents (n8n)
- Database: MySQL schema design and optimization
- Domain edge: an MBA in Finance — I understand fintech, healthtech and SaaS products, not just the code

A couple of recent builds (full case studies in my Portfolio section below):
- InvestorVault — a full investor-management portal (Spring Boot + React + JWT + MySQL) with secure authentication and financial data handling
- An AI job-matching agent (n8n + Claude API) that scores opportunities and drafts tailored responses automatically

I'm a clear communicator, I hit deadlines, and I treat your product like my own — whether it's a new API, a full-stack app, an AI-powered feature, fixing an existing Spring Boot system, or shipping an MVP.

Send me a note about your project and let's set up a quick call to see if we're a fit.
