You will get a scalable Java Spring Boot REST API backend for your web or mobile app

Project details
Need a Java backend that scales without breaking? I build production-ready Spring Boot APIs that power SaaS platforms, e-commerce systems, and mobile app backends with the architecture, security, and testing serious projects require.
Most freelance Java work fails for the same reasons: shaky auth, no tests, no documentation, and code that turns into a nightmare the moment you try to scale or hand it off. I solve for all four from day one.
WHAT YOU GET
✓ Spring Boot REST APIs with clean architecture (SOLID principles)
✓ JWT authentication & Spring Security (role-based access control)
✓ PostgreSQL, MySQL, or MongoDB integration with optimized queries
✓ Swagger / OpenAPI documentation auto-generated for every endpoint
✓ Unit & integration tests using JUnit and Mockito
✓ Docker containerization, ready for AWS, Azure, or any cloud
✓ Clear commit history and a README the next dev can actually follow
WHO I WORK BEST WITH
Founders shipping their first SaaS, agencies needing reliable backend support, and teams rescuing a project that went sideways with another developer.

Job Success
Birmingham, United Kingdom - 1:11 am local time
I'm a full stack engineer specializing in production web apps built with Next.js or Vue.js on the frontend and Java Spring Boot or Node.js (TypeScript) on the backend. I've worked on systems processing 500K+ daily queries with sub-100ms response times, and I bring the same discipline to a 2-week MVP as I do to a long-term platform build.
▸ MY CORE STACK
Frontend: Next.js (App Router, SSR/ISR), Vue.js 3 (Composition API), TypeScript, Tailwind CSS
Backend: Java Spring Boot, Node.js with NestJS, REST + GraphQL APIs
Databases: PostgreSQL, MongoDB, MySQL, Redis, ElasticSearch
Auth & payments: JWT, OAuth 2.0, Stripe, third-party API integrations
DevOps: Docker, CI/CD pipelines, AWS / Azure deployments
▸ WHAT I TYPICALLY BUILD
- SaaS platforms with dashboards, billing, and role-based admin panels
- E-commerce systems with custom checkout and payment flows
- Multi-tenant applications with team/permission hierarchies
- API-first backends that serve web and mobile clients
- Performance and architecture rescue on slow or unstable apps
- Migrations from legacy stacks (PHP, old Angular, jQuery) to modern Next.js / Vue
▸ HOW I WORK
Every project follows the same discipline: clear scope upfront, clean architecture (SOLID, separation of concerns), proper testing, security baked in (not bolted on), and documentation the next developer can actually use. You'll get progress updates without having to ask, and I flag risks early before they become budget problems.
I'm direct about what's realistic in your timeline and what isn't. If your project would be better solved with a simpler tool than what you've asked for, I'll tell you.
▸ NEXT STEP
Send a message with what you're trying to build and a rough timeline. I'll reply within a few hours with honest thoughts on scope, stack fit, and a realistic estimate.
Steps for completing your project
After purchasing the project, send requirements so Muzamil can start the project.
Delivery time starts when Muzamil receives requirements from you.
Muzamil works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements review & technical kickoff call
We confirm scope, endpoints, data models, and integrations. You receive a written project plan with milestones before any code is written.
Architecture & database design
I design the system architecture, define entity relationships, and document the database schema. You approve before development starts.
