At Expensya, I work on the infrastructure behind corporate payment products, including card issuance, bank-account onboarding, and fund automation. My work has included resolving payment production incidents and delivering a bulk card creation feature from requirements through production.
I refactored the payment service with Facade, Factory, and Strategy patterns to support a provider-agnostic architecture. I also authored SQL migrations to address data integrity and index performance issues, and maintained the Azure DevOps release pipeline.
At Luceor, I built the frontend of a proof-of-concept Android application using Java, XML layouts, and Google Material Design components. The interactive prototype helped the team evaluate mobile feasibility and UX direction.
