Sr. Java Developer
Soufian worked on our backend team, where he made strong contributions to our Java and Spring Boot services. He delivered production features spanning REST APIs, scheduled workflows, validation and error handling, database migrations, audit logging, and automated testing. Soufian was reliable, communicative, responsive to feedback, and easy to work with. I’d gladly recommend him for Java and Spring Boot backend development.

Guercif, Morocco - 10:52 am local time
I help startups, SaaS teams, and product companies build reliable web applications, clean up messy systems, and ship features that are ready for real users.
My main stack is Java, Spring Boot, React, Next.js, Supabase, PostgreSQL, MongoDB, Stripe, Docker, AWS, and REST APIs. I’m comfortable working across the full product: backend architecture, frontend development, database design, authentication, API integrations, performance, and debugging.
A lot of clients come to me when they already have something built, but it needs to become more stable, scalable, or production-ready. I can jump into an existing codebase, understand how the system works, find what is broken, explain it clearly, and implement clean fixes without creating new problems.
On the backend, I build Spring Boot services, RESTful APIs, authentication and authorization flows, database schemas, business logic, and third-party integrations. I also work with Spring Security, Spring Data JPA, Hibernate, JWT, PostgreSQL, CI/CD, GitHub, testing, code reviews, and performance optimization.
On the frontend, I build responsive React and Next.js applications with clean user experience, reusable components, TypeScript, JavaScript, HTML5, CSS3, state management, and smooth frontend/backend communication.
I also work with Supabase-based products, including Supabase Auth, PostgreSQL, Edge Functions, RLS, user state, entitlement logic, and backend cleanup. If your app uses Stripe subscriptions, checkout, webhooks, paid access, or SaaS billing logic, I can help make the flow correct and stable.
I can help with:
◦ Java Spring Boot backend development
◦ REST API design and third-party API integrations
◦ React and Next.js frontend development
◦ Supabase Auth, RLS, PostgreSQL, and Edge Functions
◦ Stripe subscriptions, checkout, and webhooks
◦ Authentication and authorization with JWT/Auth0
◦ Database schema design and backend architecture
◦ SaaS MVPs, proof of concept builds, and production-ready systems
◦ Debugging, performance optimization, and code cleanup
◦ Clean architecture, maintainable code, testing, and documentation
I work independently, communicate clearly, and stay focused on practical delivery. My goal is simple: help you build a system that works well now and is easier to maintain later.
