🏆 Top Rated Plus | 14,000+ Hours | 100% Job Success Score | 5★ Feedback 💼 12+ years of Experience | Java · Spring Boot · AWS · DevOps · AI Integration 🚀 FinTech · Banking · Enterprise SaaS · Cloud-Native Systems Over the past 12+ years I have been building production-grade Java backends, scalable cloud infrastructure, and enterprise systems for FinTech, banking, healthcare, and SaaS businesses. Over the last two years I have been helping businesses integrate Generative AI, LLMs, RAG pipelines, and AI workflow automation into production backend systems. I specialize in Java, Spring Boot, Microservices, AWS, PostgreSQL, MongoDB, Docker, Kubernetes, and AI integrations using Claude API, OpenAI, and LangChain - helping companies build reliable, scalable, and production-ready systems that go beyond demos and actually work under real load.
