Financial Services Buenos Aires, Caba 51–200 employees Privately Held

Wayni operates a fintech lending platform with a polyglot backend spanning PHP, Laravel, .NET Core, and Node.js, deployed across AWS microservices. The stack includes Mixpanel, Amplitude, and Google Analytics 4 for metrics, Mercado Pago for payments integration, and Redis + DynamoDB for state management—a shape typical of transaction-heavy consumer fintech. Active projects show a shift toward wallet functionality and external API integrations, while pain-point clustering around data quality, reporting automation, and legacy modernization indicates an organization scaling from ad-hoc analytics toward systematic data operations.
