Cashela — Payments platform

A cross-border payments and digital wallet platform. I lead delivery across its three fronts —backend, web and mobile— and build the financial core: the double-entry ledger over the money paths, pay-in and payout integrations with multiple providers (quoting by capability, automatic dispatch, signed callbacks and idempotency) and the progressive migration of the legacy monolith to hexagonal architecture, service by service, with feature flags and shadow-first cutovers so the business never stops. On the customer web dashboard I rebuilt the home, the transaction history and beneficiary management, and unified the send wizards on top of an in-house component library so every service —remittances, top-ups, bill payments and gift cards— shares one flow instead of maintaining six different variants.
