At ViaCarte, I develop .NET APIs and background services for card issuing, wallets, member operations, and internal tools. I take backend features from requirements and data design through implementation, deployment, and production support.
I built a worker that ingests Visa and Mastercard reports for operational reporting and reconciliation. I also delivered fee reversal and manual adjustment tools for the operations team and reconciled data affected by duplicate fee records.
At Versatec, I developed C# and .NET services and REST APIs for banking core and transaction processing systems. I maintained Visa authorization and routing components, and implemented messaging requirements for routers and POS terminals.
At ProSolutions, I developed .NET Framework Web APIs for accounting and financial reports, and built an inventory management system for vending machines. My work has included SQL Server and PostgreSQL data access, along with MySQL application and database logic.
