At Xquic, I developed the hotel revenue recovery system, including a Python and FastAPI OTA reconciliation engine and core billing modules for commissions, virtual cards, and Stripe Connect. Automated reconciliation helps hotels save thousands.
I led Xquic's first PCI DSS v4.0.1 compliance program toward a QSA audit, authored security procedures, and established an internal compliance audit process. I also improved page performance by up to 40% through PostgreSQL optimization and Redis caching.
At Devsinc, I decoupled Visa clearing file generation into a Go settlement service that ran 15 times faster, and contributed to payment dispute tools that helped prevent monthly fraud losses. I also migrated a U.S. benefits platform to Rails and TypeScript, improving transaction speed by 40%.
Earlier, I built data extraction and processing systems, improved a finance platform's page load time by 60%, and worked on adaptive learning features and teacher dashboards. I use Ruby, Rails, Python, Go, and React across backend and full-stack work.
