Dan-Stefan Dogaru

Co-founder and CTO at Superliga Fantasy

Co-founded the official Fantasy game of the Romanian First Football League (SuperLiga). In a small startup environment, I led work across technology, development, social media, marketing and business. Implemented a NestJS backend with WebSockets and Redis to serve real-time data, a Go service to calculate points and standings independently from the API, and MongoDB for data storage. Built an Ionic Angular cross-platform mobile app, deployed AWS (EC2, S3), and automated workflows with N8N. Integrated SendGrid, OneSignal, Firebase and Google Analytics for miscellaneous tasks and analytics.

The project leveraged Ionic, Nest, MongoDB, and included Three.js for 3D rendering.
