Dmitry – Flutter, Java, Dart

Do you know what feels better than having an app developer with a marketing background on your team? Nothing. Nothing feels better than that, and that’s exactly what Dmitry is going to bring to the table. Dmitry has 10+ years of experience in various roles (including marketing) in tech. For the past 5 years, he’s been focused entirely on gaining hands-on commercial experience in app development, and he’s now exclusive to Dart and Flutter. He loves Flutter so much, he’s deeply involved in the community, and our mind control app says he often dreams of it at night. A real Flutter-flattering guy.

Head of the Development Team
Nov 2020 - Jun 20216 months
Project Overview

The customer provided a complete REST API for the dating application. The challenge was to create two very similar dating apps based on this API, but on top of the app, the team had different match initial users' requirements: first was video streaming, and the second was the question test. As a solution, it was decided to separate all REST API: OAuth with email, FB, Google, Apple, chat, like, coins(spend and buy), profile; separate dart package to reduce development and support time, and on top of this package create two applications.
