Portuguese language pronunciation app.
Manish and team did an excellent job on my Portuguese pronunciation app. I had no idea what I was doing and approached them with my basic concept and ideas. They endured my discovery process and managed to make it come alive.
I asked a lot of questions and had lingering doubts because of a past bad experience with a developer, but Manish and team were honest, diligent and capable.
