Case study

Olá Cliente

Sinapse's principal Flutter initiative, developed between November 2022 and July 2025. A sustained mobile ownership role, with requirements aligned directly with the Product Owner and integration into existing systems.

My responsibility

Principal Flutter developer at Sinapse, working directly with the Product Owner and supporting Kotlin and ASP.NET systems.

Delivery status

Product delivery and support

Developed from November 2022 to July 2025, including production readiness and continued support. Current availability is not recorded.

Context

Sinapse needed a complete mobile product for telecom providers and customers, bringing together support, service, account and payment-related flows.

My contribution

I built the application from scratch and owned the implementation and evolution of Flutter features. I worked directly with the Product Owner to align requirements and delivery. I also supported a legacy Kotlin Android application and ASP.NET APIs when needed.

Decisions and integrations

Flutter/Dart with Provider/Notifiers, GetIt and separation of responsibilities. REST and WebSockets connect service, chat, real-time location and technician tracking. Google Maps/polylines, Firebase, payment-related integrations and CI/CD practices are part of the work.

Delivery and outcome

Olá Cliente became Sinapse's first complete Flutter/mobile product and expanded its ability to offer a mobile experience to B2B telecom customers. My work included production readiness and continued support.
