Java Microservices Architect & AWS Cloud Engineer | 15 Years in Fintech & Enterprise Systems I design and build distributed backend systems that scale — clean architecture, reliable infrastructure, and zero shortcuts. With 15 years of hands-on experience in fintech, banking, payments, and enterprise product development, I specialize in Java/Spring Boot microservices and AWS cloud architecture. I've worked on systems where downtime isn't an option and where bad architecture decisions cost real money — that experience shapes how I approach every engagement. What I bring to your project: — Microservices Architecture Spring Boot, Spring Cloud, Netflix OSS (Zuul, Eureka), API Gateway, Service Discovery, Circuit Breaker, SAGA pattern. I design systems that are independently deployable, observable, and built to evolve. — Event-Driven Systems Kafka integration, Pub/Sub architecture, Producer/Consumer implementation. I build asynchronous pipelines that decouple services without sacrificing reliability. — AWS Cloud Infrastructure EC2, VPC, RDS, S3, Route 53, ALB, Elastic Beanstalk, Load Balancers. I handle both architecture design and hands-on deployment — not just one or the other. — DevOps & CI/CD Jenkins, AWS CodePipeline, GitHub Actions, automated deployments across Linux and Windows environments. I set up pipelines that let your team ship with confidence. — Fintech Domain Expertise Banking, mortgages, payments (NEFT, RTGS, IMPS, Stripe, PayPal, RazorPay), KYC/eKYC, CIBIL, FIS/Fidelity integrations. I understand compliance-sensitive systems and how to build them correctly. — GenAI Integration (emerging capability) OpenAI, Gemini API, Ollama, AI workflows and chatbot development — for clients looking to embed intelligence into their existing backend systems. Who I work best with: Teams or founders building serious backend infrastructure who need a senior engineer they can trust to make good decisions independently. I'm not a code-for-hire resource — I'm a technical partner who will tell you when something is being built the wrong way. Tech stack: Java, J2EE, Spring Boot, Spring Security, Kafka, Hibernate, JPA, MySQL, MongoDB, ElasticSearch, Node.js, PHP, Laravel, Python, Flask, AWS, Jenkins, Docker, Kubernetes, Linux, Nginx, Apache If you're building something that needs to work at scale and hold up under pressure — let's talk.
