Ecipay - Portal de Clientes
The challenge
Ecipay needed a portal where payment leaves no doubt. Confusing histories and ambiguous confirmations breed distrust and avoidable support. We needed radical clarity.
Payment gateway
Guided payment flow with inline validation, visible states and unequivocal confirmation. Double charging is prevented and each step is communicated in human language, not internal codes.
Guided pay — no ambiguity
History & traceability
Lists with useful filters (date, status, amount), search and export. Each transaction exposes its timeline and receipt, cutting support queries.
Filterable and exportable history
Admin panel
Ops view for the internal team: reconciliation, incidents and metrics. Dense yet legible design, prioritizing the next action per state.
Microservices
Spring Boot backend with decoupled microservices. Each domain (payments, users, notifications) evolves and scales independently without dragging the rest.
Decoupling — independent evolution
Results
Reliable portal that cuts uncertainty and support load. Extensible base for new payment methods without rewriting the main flow.
