What I'm looking for

I’m looking to lead backend and architecture work end-to-end in secure, high-impact systems—especially Java/Spring environments—where I can own delivery, improve performance, and mentor engineers while applying clean architecture and strong engineering practices.

I’m a Senior Backend Engineer with 17 years of experience in Fintech, Banking, and enterprise systems, leading full SDLC delivery across complex, high-impact projects. I specialize in Java/Spring Boot and security, using clean architecture approaches like DDD, Hexagonal Architecture, and Modular Monolith to build reliable platforms.

At DerivSoft, I directed and participated in end-to-end delivery of 15+ complex software projects, managing requirements, architecture, and documentation to reduce time-to-market and QA rejection rates. I’ve also automated high-volume data flows—such as VISA transaction processing and 70k+ record ingestion—using ETL with Spoon and Spring-based services, improving processing speed and reducing manual reconciliation.

I also design and ship production systems that perform under real constraints: building Flutter mobile experiences backed by secure Spring Boot REST services on AWS, architecting a Payments Alert pipeline, and delivering a Manufacturing Execution System with real-time traceability. I enjoy mentoring teams to ensure architectural and code alignment, and I’m driven by results like faster loan approvals, reduced processing steps, and fewer defects per KLOC.
