Java Backend Engineer with 1.5 years of experience building and maintaining Spring Boot microservices on a high-volume FinTech remittance platform processing 1M+ transactions/month across 50+ countries. At Al Mulla Exchange, I work across 10+ production microservices handling cross-border remittance, FX rate management, and compliance workflows. Some of the key things I have shipped:
→ EDD AML/CFT Compliance Workflow — designed a full state machine (Hold, Pending Review, Approved, Rejected, Closed) with a role-based approval matrix across Branch Staff, Compliance Officers, and General Managers, plus immutable audit trails across 50+ branches.
→ IP Geo-Restriction Security Module — built using Spring Boot filter chain, CIDR range validation, and 24-hour Redis caching to block unauthorized foreign-origin requests in real time.
→ OTP-Based Device Unlock API — verified registered mobile and email before dispatching OTP, enabling secure self-service device unlock.
→ Excel KYC Pipeline — Civil ID bulk upload and multi-section KYC report generation using Apache POI, cutting manual processing time by 40%.
→ Performance: Reduced MySQL load by 40% via Redis caching, cut API response times by 25% through composite indexing, and integrated Elasticsearch for sub-100ms FX analytics across 50+ currencies.
