Hey, see you're looking at my profile 😉 Nice to meet you! I'm a 𝗝𝗮𝘃𝗮 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 𝗮𝗻𝗱 𝗙𝘂𝗹𝗹 𝗦𝘁𝗮𝗰𝗸 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 with 7+ years of experience building backend systems, SaaS applications, software platforms, web applications, and enterprise systems for clients across fintech, logistics, telecommunications, retail, healthcare, and SaaS. As a Java Developer and full stack developer, I design, build, and ship production-ready software systems and platforms end-to-end: architecture, backend, frontend, and deployment. On the backend, my core stack is Java, Core Java, Spring Boot, and Spring Framework, building REST APIs, microservices, and scalable software systems with Hibernate/JPA, SQL, PostgreSQL, MySQL, and MongoDB. As a Java backend developer, I've designed 120+ REST APIs and built 10+ microservice architectures for systems and platforms serving 10K to 500K+ users. I've shipped 35+ production software systems, platforms, and web applications as a full stack developer and Java developer. On the frontend, I build with React, Angular, JavaScript, and TypeScript, delivering full stack web applications and SaaS platforms where clean UI meets solid backend architecture. Whether it's a software system, an internal platform, or a customer-facing SaaS product, I work across the whole stack to make sure the system holds up in production. For infrastructure, I work with AWS, GCP, and Azure, using Docker, Kubernetes, and CI/CD pipelines to keep systems, platforms, and software reliable at scale. The software systems and platforms I've maintained as a full stack developer and Java developer have held 99.9% uptime — the result of solid monitoring, careful deployment practices, and proactive system design. Performance is something I take seriously on every platform and system I build: as a Java Developer, I've cut API response times by up to 60% and improved overall system performance by 40%+ through targeted software architecture improvements rather than costly rewrites. I've also worked extensively with enterprise-level database schemas, optimizing complex SQL queries and data models across tables with 100K+ records. Beyond Java, I also write Python, PHP, and Node.js when a software system or platform calls for it, and I've worked on .NET/C# projects too, including reviving a legacy .NET system onto currently supported frameworks. As a full stack developer, I go where the project needs me. Java is my strongest ground, but I adapt the stack to the system. As a Java Developer, I've also earned certifications in Java Backend API Development and Java Microservices Engineering — production depth, not just a keyword on a profile. Beyond hands-on development, I've led teams, mentored junior developers, and managed cross-functional projects across software systems and SaaS platforms. My clients get clear communication, fast responses, and maintainable software code that still makes sense six months later. 🤝 Let's talk I'm open to long-term collaborations as a Java Developer or Full Stack Developer — Spring Boot, backend systems, SaaS platforms, enterprise software, microservices, and web applications — plus related work in cloud migration, API integration, database development and optimization, and legacy system modernization. If you need a Java Developer or Full Stack Developer who ships reliable SaaS platforms and software, let's talk.
