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.

Thank u for review my profile I am a professional and experienced developer. I have experience in development for the last 11 years. Throughout my career I've developed wide range of projects for Web, Desktop and Mobile. If hired by you, I will put my creative and entrepreneurial capacity on earn prospects for your business.

The 3am angle is the honest one for a backend person, so I've built the whole thing around it. Nobody calls a developer at 3am about the frontend. They call about the payment that double-charged, the queue that backed up, the database that locked under load. I build the parts that get called about, and I build them so they don't. Full Stack Developer, 10+ years. Java and Spring Boot on the backend, React and Next.js on the front, one engineer owning the whole feature instead of handing half of it over a wall. Fintech, logistics, healthcare, SaaS. Different industries, same rule: it has to survive real users, not just pass a demo. Track record: ⭐ 100% Job Success Score 🏆 10+ years commercial development, 30+ production systems shipped 👥 Led teams of 10+ developers through full-cycle SaaS delivery 💰 Fintech platform processing $15M+ annually 🚚 Logistics platform scaled to 1.2M+ daily API requests through Redis optimization 📈 SaaS MVP built in 6 weeks that secured $500K+ pre-seed 🏗️ Multi-tenant SaaS with role-based access and tenant isolation enforced at the database, not in the app ⚙️ Monolith to Spring Cloud microservices migrations 🔒 HIPAA-aware healthcare platforms and PCI-conscious payment systems 🔗 Webhook-driven and GraphQL API layers into third-party financial systems 🤖 OpenAI and Claude APIs in production workflows 🧠 Claude Code and Cursor daily, every line reviewed and owned before it ships What I build: - Full-stack features end to end: React, Next.js and TypeScript on the frontend, Java, Spring Boot and Node.js behind it - Backend architecture in Spring Boot, Spring Cloud, Spring Security and Hibernate, with Kafka, Redis and RabbitMQ added when scale actually demands it rather than because they look good on a diagram - REST and GraphQL APIs, webhook integrations, OAuth2 and JWT, role-based access, audit logging for compliance-sensitive systems - Database design and query optimization across PostgreSQL, MySQL, MongoDB, Redis and Elasticsearch - AWS (EC2, S3, RDS, Lambda, ECS), Docker, Kubernetes, Terraform, Jenkins, GitHub Actions - Stripe, Plaid, QuickBooks, Twilio, Firebase, OpenAI and Claude integrations in production - Clean, testable code on SOLID principles and TDD, not process for its own sake Fintech payments, HIPAA-aware healthcare, real-time logistics, multi-tenant SaaS, CRM and ERP, marketplaces. By the end of a first call I usually recognize the shape of the problem and where the architecture gets expensive if it's wrong early. The code I leave behind reads without a walkthrough, whether that's your next engineer or me in six months. Sole engineer on a build or inside a small team, blank repo or someone else's codebase. All fine. Share what you’re building and where you’re stuck. Let’s find the right way forward - message me to start!
