Kind words from colleagues and managers on LinkedIn
"
“Toan is one of the rare types of talent that a manager can come across in a workplace, a combination of both technical skills as well as soft skills. Showing passion and care towards both product as well as architecture. In his time at Zeals, Toan didn't shy away from challenges and strict timelines, always doing his at most best to match the expectations as well as showing care to the people he interacted with or the stakeholders he represented. I would highly recommend him for any company who would consider him as a potential hire.”
"
“I had the pleasure of working closely with Toan, who served as our Tech Lead and Senior Frontend Developer. He was always willing to assist team members and took the time to review code thoroughly, ensuring both functionality and high-quality standards. What stood out the most was his proactive approach to resolving critical issues — he not only took ownership of complex challenges but also documented his solutions, allowing the entire team to follow his steps and learn from it. I highly recommend Toan for any role that values technical excellence and team-oriented leadership.”

“Toan joined my team as a fellow Frontend lead at Zeals midway through a complete rewrite of our application. Faced with an impending deadline, Toan quickly took ownership of key features, leading a team of seven frontend developers with keen project management, milestone creation, code review, and technical guidance. At the same time, he spearheaded an architectural rewrite that saved our application from severe performance issues. With Toan, you are getting a high performer who is still hungry to learn and contribute. I give my highest recommendation to anyone who has the opportunity to work with him.”

Having him in the team will not only give you the work results but he could also be a good friend.”
