Doan Duc Tin
Founder Product Owner Tech Innovator
Known as MrSat, Doan Duc Tin (Đoàn Đức Tín) builds reliable systems and writes down what that work actually takes. MrSatDev started as a place for classmates to share documents and questions. It is now an early-stage studio for backend development, cloud infrastructure, DevOps, and automation.
The aim is simple: make hard technical ideas easier to use, so engineers and small businesses can keep learning, building, and growing.
The startup
MrSatDev is an early-stage business. We are a tight-knit team of about 10 people, focused on software and digital transformation for small businesses (SMBs).
We build better solutions in cloud infrastructure, automation, and modern software development. Next to the client work we publish technical blogs, tutorials, reusable code templates, and agents, so the studio can actually compete in the market.

Early contributors
The studio is a tight-knit team of about 10. These four were here early and helped the site become something other people could use.
Tran Phuong Nam
Content creator
Nam's posts gave the blog its first real body of writing. That work is still part of why people came back.
You can’t start the next chapter of your life if you keep re-reading the last one, life always offers you a second chance. It’s called tomorrow.
Tran Phi Anh
Advertising
Phi Anh helped more students find the site. The bug reports from that time shaped what we fixed next.
What lies behind you and what lies in front of you, pales in comparison to what lies inside of you. When life gives you a hundred reasons to cry, show life that you have a thousand reasons to smile.
Pham Duy Dat
Content creator
Dat was the first writer to publish here. That first post made it easier for everyone who followed.
Coming together is a beginning; keeping together is progress; working together is success. If you want to go fast, go alone. If you want to go far, go together.
Nguyen Duc Cong
Supporter
Cong and his team backed the site from the first release. That support is why the project kept going.
Success is not final, failure is not fatal: they are the courage to continue that counts. The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
