Sano Seiichi

As you are fully aware the team at 3SI has been making good progress on this tight and challenging project. Everything that I’ve asked of them they have delivered and for that I’m very pleased.We still have a little more to go before production launch but I want to let it be known that Tuan, Phong, Manh and other team members who had contributed a huge amount of effort and for that I’m truly grateful. As a recognition of the tremendous and super hero efforts I would like to make a small gesture of my appreciation by treating the entire Project team at 3S to a very nice dinner to the sum of $600USD...

3S Company went beyond expectations. I plan on working with them immediately to complete my plans.

Louis O'Reily

Excellent project work. The team went above and beyond the call of the project to ensure it was completed perfectly and on time. Highly recommended.

Marcel Kaminstein

今後も案件を御社に優先的にお願いしたいと考えておりますので、宜しくお願いいたします。

Ours project is a complicated one that has nine elements that need to work together. The original programmer quit the project because of its complexity. The staff at 3S Company is diversified so there is someone who is proficient at whatever skill is needed. Due to the complexity of our project, I have had the opportunity to work with six different programmers. All of them have been hard working and cooperative. Despite the twelve hour time difference, I have been able to talk over Skype in both the morning and evening. That means that sometimes the programmer is up until 11PM. As a consequence of their diverse talents and willingness to communicate whenever needed, my project is moving along at a rate that meets my expectations. Oh, it helps a lot that they all speak English.

期日を守って頂けるし、こちらの曖昧な指示に対しても行間を読んでいただけるので、非常に良いと思います。また、進捗管理もしっかりしており、安心してお任せできます。ただ、短所を挙げるとすれば、デザイン力です。ここが改善できれば、依頼できる案件の幅も広がると思います。

黒田

I must say that I am very satisfied about the professional work delivered by the Windows team and it would be my pleasure to offer you more projects / new apps. I would like to thank all members of the team for their excellent work ! As soon as the app is released, I look forward to further development of this application. There are many new functions that will be added in the "future.
