What I'm looking for

I'm looking to build reliable end-to-end web systems, especially financial products, where I can strengthen business logic, improve maintainability, and contribute across backend APIs and frontend interfaces.

At Wimix Solutions & Services, I helped build a financial platform supporting an institution’s transition toward becoming a banking entity.

I implemented the full cash deposit and withdrawal lifecycle, including transaction creation, validation, conditional approval, and reversals. I also built more than 30 NestJS and TypeScript REST endpoints for financial modules.

I develop Vue.js and Quasar interfaces for cash deposits, withdrawals, checking accounts, and cash management, connecting frontend modules to backend services through REST APIs.

I focus on reliable end-to-end systems by strengthening business rules around account status, currencies, balances, and transaction authorization. I also identify logic errors, reduce duplicated code, and improve maintainability across financial modules.
