Work Experience

Associate Software Engineer

Volante Technologies

Jan 2024 - Sep 2025

Led Apache Camel migration (2.x → 3.x → 4.x) across production payment systems, eliminating framework-compatibility risk and ensuring uninterrupted transaction processing by upgrading transport configurations. Engineered ISO 20022 mandate formats (PAIN.009/010/011) and SWIFT MT102/MT103 message structures for OMS and SWIFT, powering end-to-end mandate lifecycle management and standardized transaction data transmission. Cut build time by 40% by re-architecting the build pipeline for parallel module execution, shortening release cycles and accelerating delivery of client-requested fixes and features. Standardized product scripts and source code across multiple payment rails, reducing new-rail onboarding time by 50% and enabling a scalable multi-rail architecture supporting 10+ payment formats. Built file- and field-level duplicate checks for payments, preventing duplicate transaction processing across high-volume flows and reducing manual reconciliation effort by 70%. Built microservices-based payment services in Spring Boot, integrating Core Java/SQL-driven features and improving system efficiency by 25% through GitLab-managed version control.
