I’m a senior software developer focused on designing and building scalable fintech and enterprise banking applications. I work across distributed systems, REST APIs, performance optimization, and production support—using Java, Spring Boot, microservices, Kafka, RabbitMQ, and MySQL to deliver reliable transaction-heavy services.

In my recent work on multi-tenant banking solutions, I improved asynchronous processing and distributed communication with RabbitMQ and designed Multi-Tenant + Kafka architecture to enhance scalability and resilience across multiple cooperative banks. I also created centralized configuration/property frameworks and multi-module parent POM architecture, improving maintainability and reducing build redundancy by 20%, while enabling tenant-specific configurations on a shared codebase.

Earlier, I developed and maintained banking payment and payout processing systems, including high-volume payouts with strong availability and fault tolerance. I’ve built reconciliation and transaction validation services, secure RESTful APIs (including OAuth 2.0 authentication and token management), automated reporting (PDF/Excel/CSV), and investor notification workflows with webhook/scheduler services, while migrating ledger reporting from Tableau to Java-based Spring REST and optimizing MongoDB pipelines to reduce report generation time from 45 minutes to 10 minutes.
