Mobile App Development Review from Vasko Markovski
Our company hired them to create an app designed to help expatriates find housing. A project manager and two developers from Saigon Technology worked closely with our team for the app's development. At the start, their team and ours gathered the information needed for the project and planned out how to build the product. They then designed the app's interface and added features. In the end, we launched the app successfully, and our client was satisfied with it.

Priyanshi Verma's Review Sourced from Google
Unprofessional, Mentally Draining, and Disrespectful Work CultureMy overall experience with this company was extremely toxic. During my short tenure, I observed several deeply unprofessional practices that left a lasting negative impact on me:•Salaries were often delayed, without prior communication or explanation.•There were unexplained deductions in monthly salary, and any attempts to raise concerns were either ignored or dismissed by HR.•The HR department was shockingly rude. I personally witnessed employees being humiliated or emotionally broken when they decided to resign — some even left in tears.•No proper Full and Final Settlement (FNF) or professional offboarding process was followed. It’s like once you resign, you’re treated as if you never existed.•Even after resignation, the company continued to send intimidating and threatening emails and begging for small amount of money like 20k, showing a complete lack of empathy — especially towards people who were already in a tough personal or financial situation.If you’re considering joining, please rethink carefully. Make sure everything is documented in writing — verbal promises mean nothing here. A company’s real face shows not when you join, but when you try to leave. And unfortunately, this one shows zero professionalism, zero compassion, and zero respect for employees.

One of the worst organisation I have ever experienced . Exit process is worst moreover company doesn’t respond on your final f&f queries and literally one has to chase to get their full n final payment. Depending upon clients requirement organisation and their leaders push their employees and even salary is deducted if it is not billed as per clients need. Pathetic to be honest. Lala companies are doing better than this in country.
