Great technology isn’t just for big companies

System Architect Global (SAG) was founded in 2021 in Hanoi, from a simple belief: great technology should not belong only to large corporations. Small and medium-sized businesses can access and own well-built systems too, with the right advice and a reasonable budget.

That is why SAG brings enterprise-grade engineering to small and medium-sized businesses at a reasonable cost, and stays with clients for the long run instead of handing over and disappearing.

Our commitment

SAG never leaves clients behind

SAG is especially ready to take over websites that are broken or were abandoned by a previous vendor.

Free solution consulting

Before you spend anything, SAG reviews your current setup, listens to your goals and proposes a solution that fits your business and budget.

3-year warranty

This is not an ordinary product warranty. SAG takes full responsibility for every line of code we write.

Lifelong advisory support

The project ends, the partnership doesn’t. If your website is attacked or goes down, SAG provides 24/7 emergency support.

Founder

Nguyễn Tấn Việt – CEO & Founder

“Nguyễn Tấn Việt didn’t start in a boardroom — he started with lines of code.”

A software engineer by background, Nguyễn Tấn Việt spent many years building systems hands-on for large organizations in technology, retail, finance and insurance. Those years working at the deepest layers of the system taught him how every architectural layer and every technical decision affects a business’s operations and costs.

In 2021, he founded SAG with one goal: to bring that engineering capability to small and medium-sized businesses, companies that deserve good systems but are often overcharged or left with unfinished projects.

SAG’s engineers are people who have worked with him before, chosen for their skills and a shared belief: clients deserve real value, not pretty promises.
