I'm a Full-Stack Java Developer with over 8+ years of industry experience. I excel in all aspects of Java application development, from design and development to deployment. I have a proven track record of building robust and Scalable applications across diverse domains. My Expertise Full-Stack Development: Java: Core Java, multithreading, OOP, Spring, Hibernate, Struts, J2EE. Frameworks & Libraries: Spring, Hibernate, JavaFX, Apache Struts. Microservices Architecture: Spring Cloud, Netflix OSS, service discovery, load balancing, tolerance mechanisms. Web Development: JSP, Servlets, RESTful APIs, Angular, React, HTML, CSS, JavaScript. Databases: MySQL, PostgreSQL, MongoDB, Redis. Testing & Debugging: JUnit, Mockito. I also use GitHub Copilot and Claude Code to deliver the best solutions. ✔ LLM integrations (OpenAI, Claude, etc.) ✔ AI-assisted workflow automation ✔ Prompt engineering & optimization ✔ RAG based enterprise search solutions ✔ AI code acceleration using tools like Cursor ✔ Designing AI-ready Microservices architecture Java Solution Architect: Designing scalable solutions with Java, Spring, Hibernate, and microservices. DevOps: Cloud setup, infrastructure management, CI/CD. Proficient in AWS (Lambda, EC2, S3, Redshift, SageMaker, Cognito) and GCP (VMs, Google cloud storage). Domain Experience: Insurance, finance, healthcare, e-learning, e-commerce, travel, real estate, logistics, supply chain, social networking, and education. CRM and ERP systems.

I've been writing Java backends for 10 years, REST APIs, microservices, Kafka pipelines, and Spring Boot on AWS. That's the foundation. What's changed recently is how I work. Over the last year, I've started pairing that backend experience with AI tooling, specifically Claude (Anthropic) and Kiro CLI, to build faster and catch architectural problems earlier. I call it vibe coding: using AI as a thinking partner, not a shortcut. The output is still production-grade, just delivered faster. What I actually built: - Scalable REST and event-driven APIs with Spring Boot + JPA - Microservices with API gateway, service discovery, and service mesh - Async messaging with Kafka and RabbitMQ - AWS deployments with Docker, Kubernetes, and CI/CD pipelines - MCP server integrations and RAG-based AI features for applications The AI tooling side is real work, not a bullet point. I've built MCP servers, set up RAG pipelines connecting LLMs to structured data, and helped clients add AI capabilities to existing Java/Spring apps without rebuilding from scratch. I write clean code, document as I go, and communicate without disappearing for days. If your project needs solid Java backend work, or you're exploring adding AI features to an existing system, I'm worth talking to.

I build scalable, high-performance backend systems that handle real-time data and production workloads. With 10K+ earnings, 900+ hours, and 5★ client feedback, I help startups and enterprises develop reliable backend services using Java and Spring Boot. 💡 What makes me different: I don’t just write APIs — I design systems that scale, perform, and are easy to maintain. 🔹 Core Expertise: - Spring Boot REST API development - Microservices architecture - Real-time systems using WebSockets - Event-driven systems with Kafka - Secure authentication (JWT, OAuth2) - Database design (MySQL, PostgreSQL, Hibernate) - Performance optimization & bug fixing 🔹 Proven Experience: - Built backend systems for banking & fintech applications - Developed real-time data systems (WebSocket + Kafka) - Delivered production-grade microservices architectures - Completed 14+ projects with consistent 5★ ratings 🔹 Selected Work: - Real-time stock system (live updates using WebSockets) - Spring Boot microservices backend (serverless architecture) - JavaFX + backend integrated systems 🔹 Why clients trust me: ✔ Clean, production-ready code ✔ Clear and fast communication ✔ Reliable delivery & long-term support Available: 40hrs/week Hourly Rate: $15–20 (flexible for long-term projects) If you need a backend engineer who understands scalability, real-time systems, and production challenges — let’s discuss your project.

I build backend systems for industries where mistakes are expensive — banking, healthcare, cross-border regulatory compliance. 14 years, Java and Spring Boot throughout. What I'm doing now: integrating LLM and RAG features into enterprise Java systems. Most people building RAG are Python-first and have never touched a Spring Boot estate. Most Java engineers haven't shipped retrieval. I've done both. I built and operate a production AI assistant on Java 21 and Spring Boot 3.x — chunking and embedding pipelines, pgvector with HNSW indexing, three answer routes with source grounding, Spring Security JWT, Testcontainers integration tests, running on GCP App Engine. Also: Spring Boot secure code review and remediation of security audit findings. OWASP-aligned, including AI-generated code. Stack: Java 21, Spring Boot 3.x, Spring AI, Spring Security, JPA/Hibernate, PostgreSQL, pgvector, Kafka, AWS, GCP, React, TypeScript, Docker, CI/CD. 100% Job Success, Top Rated Plus, 3,000+ hours delivered.
