You will get a Java Full Stack Developer for a real-time web platform
Top Rated
Project details
A live web platform and microservices-based system serving thousands of fans with real-time match updates, fixture schedules, and a fully functional online store. The platform had to stay responsive and accurate on match days when traffic spikes sharply, and it did. On the backend, REST APIs built with Java and Spring Boot powered the core data flow across services. Relational data, user accounts, orders, and match records were managed using Hibernate with a structured persistence layer. Dynamic content like live updates, news, and product listings was stored in MongoDB, keeping reads fast without overloading the relational database. On the frontend, interactive UI components in React gave fans a smooth experience, whether they were checking the latest score or completing a purchase in-store. Every feature shipped on schedule across multiple release cycles, keeping the platform stable and the client's season-long roadmap on track.

Job Success
Lviv, Ukraine - 12:49 pm local time
On the backend, my core stack is Java, Spring Boot, and Spring Framework, with REST APIs, Hibernate/JPA, PostgreSQL, MySQL, MongoDB, and SQL for persistence. As a backend developer, I've designed 120+ REST APIs and built 10+ microservice architectures from the ground up, for systems serving anywhere from 10K to 500K+ users depending on project scale.
I've shipped 35+ production projects as a full stack developer and Java developer, across fintech, logistics, telecommunications, retail, SaaS, healthcare, and enterprise. For infrastructure, I work across AWS, GCP, and Azure, and I'm comfortable with Docker, Kubernetes, and CI/CD pipelines to keep backend systems reliable in production as part of full stack delivery.
Performance is something I take seriously as a backend developer: on several engagements, I've cut API response times by up to 60% and improved overall system performance by 40%+ through targeted refactoring and architectural improvements, rather than costly rewrites. I've also worked extensively with enterprise-level database schemas, writing and optimising complex SQL queries, indexing strategies, and data models across tables with 100K+ records.
The production systems I've maintained as a Java backend developer have consistently held 99.9% uptime, that doesn't happen by accident. It comes from solid monitoring, thoughtful deployment practices, and knowing where the failure points are before they become incidents.
When a project calls for it, I also write Python, PHP, and Node.js, and handle frontend work in React or Angular including JavaScript for client-side logic, but as a full stack developer, my strongest work is where backend architecture meets a clean frontend implementation
My clients get clear communication, fast responses, and code that's actually maintainable six months later. I'm business-focused and I care whether the thing solves your problem, not just whether it compiles. As one client put it: he doesn't just write code, he thinks about why we need it in the first place.
Beyond hands-on Java development, I've led teams, mentored junior developers, and run cross-functional projects where the technical and human sides both needed managing.
I'm open to long-term collaborations and challenging projects involving Java, Spring Boot, full stack development, backend architecture, React, Angular, cloud systems, and microservices.
Need a full stack developer, Java developer, or backend developer who ships clean code and tells you when you're building the wrong thing? That's the conversation worth having. Drop me a message.
