PROFESSIONAL SUMMARY
Senior Software Engineer with expert-level Java backend focus—not front-end-heavy. Anchors large-scale, complex, cloud-native microservices with testable code, strong SDLC discipline, and efficient unit/automation tests. Deep distributed-systems, scaling, logging, and UML-informed design.
Hands-on payments and transactional application experience; expert SOAP/REST and test harnesses. Leads technical direction, authors architecture/design docs, manages Git/GitLab/BitBucket merge methodologies, and troubleshoots cross-domain issues quickly.
At Ink Finance, LooksRare, HSQA, and WPP Energy, built scalable backends on AWS/cloud, supported DB integrations/migrations (Oracle/RDS/DynamoDB familiarity), and optimized infrastructure for reliability—ready to drive backend initiatives for Global Channel Management’s payments-scale systems.
PROFESSIONAL EXPERIENCE
Founder & Senior Software Engineer, Backend at Self-Employed January 2026 — Present
• Write expert-level, testable Java backend code for large-scale microservices; own unit tests and automation scripts across the SDLC.
