Bathinda, India - 12:42 pm local time
I’m a Senior Java Backend Engineer with over 14 years of experience building mission-critical systems in fintech, with a strong focus on payments, lending platforms, and core banking solutions. I specialize in Java and Spring Boot, and design backend systems that are secure, scalable, and capable of handling high-volume financial transactions with consistency and reliability.

I’ve worked on systems involving payment processing, transaction workflows, loan management, and integrations with external financial services and APIs. This includes designing and building robust microservices architectures that support real-time and asynchronous processing, ensuring data accuracy, fault tolerance, and seamless service communication. I understand the importance of idempotency, transaction integrity, and failure handling in financial systems where even minor inconsistencies can have significant impact.

Security and compliance are central to my approach. I have strong experience implementing secure authentication and authorization using Spring Security, token-based systems, and role-based access control. I build APIs and backend services that align with financial industry expectations around data protection, auditability, and reliability.

From a technical standpoint, I bring deep expertise in Spring Boot, microservices, REST API design, JPA/Hibernate, and relational databases like MySQL and PostgreSQL. I’m comfortable designing systems from scratch as well as improving and scaling existing platforms, optimizing performance, and ensuring stability under load.

I also have hands-on experience with AWS and Google Cloud, and have worked on deploying and managing backend systems in cloud environments. I understand how to design cloud-ready architectures, implement CI/CD pipelines, and ensure systems are resilient, observable, and production-ready.

What sets me apart is my ability to think beyond just implementation. In fintech systems, correctness, reliability, and long-term maintainability matter more than quick fixes. I focus on building clean, well-structured systems that not only meet current requirements but are also prepared for future scale, regulatory needs, and product evolution.

If you’re building or scaling a payments platform, lending system, or core banking backend and need someone who understands both the technical and domain challenges, I’d be glad to contribute.
