You will get Spring Boot REST API Code Review & Architecture Audit
Top Rated
Project details
Are your Spring Boot REST APIs slow, insecure, or hard to maintain? I'll give you a thorough code review and architecture audit so you can ship with confidence.
With 5+ years building scalable Java/Spring Boot backends for fintech, ecommerce, and SaaS companies, I know exactly where most APIs break down: poor error handling, missing security layers, N+1 query problems, and tightly coupled layers that resist change.
What you get:
• Line-by-line review of your API endpoints and service layer
• Security check (authentication, authorization, input validation, OWASP Top 10)
• Performance analysis (query optimization, caching, connection pooling)
• Architecture review (SOLID principles, separation of concerns, scalability)
• Detailed written report with prioritized recommendations
• Code examples for each fix
I've reviewed codebases ranging from 10-endpoint MVPs to 200+ endpoint enterprise APIs. My clients consistently ship cleaner, faster, and more secure APIs after working with me.

Vu Du was quick and was able to solve and make this project work which others in the last 5 months could not complete. I will be working with Vu Du again.

I combine strong software engineering fundamentals with AI-assisted development workflows to deliver faster and safer releases. Daily toolkit includes GitHub Copilot, Claude Code, KiloCode, and Codex for code generation, refactoring, test scaffolding, and technical documentation.
Key outcomes:
- Reduced trade execution latency from 500ms to 100ms for a stock data platform processing 10K events/sec
- Built a RAG-based AI research assistant that cut analyst research time by 60%
- Led a distributed team of 8 engineers to deliver a loan management system serving 200K+ users
- Designed multi-tenant SaaS backend handling 5M+ daily requests with 99.9% uptime
Technical stack: Java 17, Spring Boot 3, Python, FastAPI, Golang, Node.js, PostgreSQL, MySQL, Redis, Docker, Kubernetes, AWS, OpenAI API, LangChain.
