Project details

Looking for a robust, scalable backend or clean RESTful API for your web or mobile application? I build production-ready backend services using Java and Spring Boot designed for high performance, maintainability, and security.

What this project delivers:
• Custom RESTful APIs: Modular architecture following clean code and SOLID principles.
• Database Integration: Spring Data JPA/Hibernate with PostgreSQL, MySQL, or MongoDB.
• Security & Auth: JWT-based authentication and role-based access control (RBAC).
• Verification & Testing: Postman test collections with automated response validations.
• Bug Fixing & Optimization: Fast debugging of API errors, CORS setup, and query tuning.

You will receive clean, well-commented source code, complete API documentation, and step-by-step setup instructions for seamless deployment.

Are you looking for a reliable Full-Stack Java Engineer to build high-performance Spring Boot backends, integrate AI pipelines, or eliminate manual QA with automated test suites? I can help.

I specialize in building secure, test-driven web applications and scalable REST APIs using Java, Spring Boot, and modern React frontends.

Unlike many developers who ship fragile code, I am ISTQB-certified—bringing an engineering rigor where automated testing, security, and clean architecture are built-in from Day 1.

What I Can Do for Your Project:
• Backend Engineering: High-throughput Java 17 / Spring Boot 3 RESTful APIs, JPA/Hibernate ORM, and PostgreSQL schemas.
• AI & Automation Integration: Connecting LLM APIs (Gemini / OpenAI) to automate internal workflows, scrapers, and business logic.
• Test Automation & SDET: End-to-end automated UI & API test suites using Playwright and Postman—cutting regression testing time drastically.
• Full-Stack MVP Development: Responsive React frontends backed by Spring Boot microservices and JWT role-based security.
• Bug Fixing & Optimization: Profiling slow database queries, debugging API bottlenecks, and code refactoring.

Featured Proof of Work:
⚡ AI-Powered Bug Tracker: Built a full-stack platform featuring automated Playwright test generation via AI and live execution runners, reducing manual test-writing effort by ~70%.

I prioritize clear communication, daily progress updates, and clean, fully-documented code handovers.
