Tuan was not only extremely knowledgable and fast, he was also very helpful and professional. He was able to answer all my questions and provide best practice guidance for an efficient solution. He was able to solve a problem others could not - I'm very glad I was able to work with him. Would highly recommend for your next project or consultation!

Premium Real Estate Headless Platform (Next.js & NestJS) with AI Integration
This was a difficult contract with serious delivery and handover issues.
The project had many bugs, repeated rework, and parts of the website appeared to be hardcoded or not properly editable, creating ongoing dependency for basic changes. I requested the source code, setup instructions, database/schema materials, and handover documents for proper review, but the freelancer did not provide a complete verifiable handover through Upwork’s official workflow.
The freelancer also conditioned delivery of the source code and Milestone 3 materials on payment release first. Due to the incomplete handover, unresolved issues, and communication concerns, I cannot recommend this freelancer for a production or business-critical project.

Ongoing software development engagement
Working with Tuan and his team has been one of the best decisions I’ve made for my company, and I can’t recommend them highly enough.
From the very first day, they approached the work as true partners rather than just contractors. They treated the project as if it were their own — taking real ownership of outcomes, caring about the details, and consistently going above and beyond what was asked. That kind of commitment is incredibly rare, and it made all the difference.
The technical work was demanding, with a lot of complexity and high standards to meet. Tuan and his team delivered clean, well-structured, production-ready work every single time. They don’t cut corners. They think ahead, anticipate problems before they happen, and proactively suggest better approaches when they think ahead, anticipate problems before they happen, and proactively suggest better approaches when they see a smarter path forward. I never once had to worry about quality slipping or messy work coming back to cause issues later.
A few things stood out throughout our collaboration:
Committed to quality — Their work is solid, reliable, and built to last. I always knew that whatever they delivered would hold up. They take genuine pride in doing things properly, not just quickly.
Solution-oriented — Whenever we hit something difficult or unexpected, they never got stuck or waited around for instructions. They came back with clear options, a recommendation, and a plan. They own problems from start to finish and see them through.
Clear communicators — Communication was fast, honest, and easy throughout. Despite a timezone difference, they were always reachable and simple to align with. No guesswork, no surprises, no chasing for updates. Just straightforward, professional collaboration.
Beyond the technical skills, Tuan and his team are simply a pleasure to work with. They’re reliable, humble, hardworking, and genuinely invested in your success. They bring a calm, dependable energy that makes the whole process smoother, and they consistently delivered on their promises.
If you’re looking for a team you can trust with serious, long-term, high-stakes work, you will not find better. They’ve earned my complete confidence, and I’ll be working with them for as long as I possibly can.
As far as I’m concerned, this is a partnership for life. Thank you, Tuan, to you and your entire team. 🙏
