Defects in financial applications can be very costly but defects in software that fly airplanes, drive cars, operate machines, or run manufactories can be very dangerous.

What Our Clients Say?

Each of you has contributed a tremendous amount of effort in getting us to this stage and I for one would like to thank all three of you for the commitment, energy and dedication it has taken to get us from a fanciful concept to a real live site.

Nadim van der Ros

We are satisfied that you handled problems very quickly and carefully. Absolutely no problem with communication at all so we find it a bit strange how you guys can acquire such skills.

Plus One



Project quality is good with smooth implementation. No problem so far.

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



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.
