We have worked with Vincent on 2 projects now and on both occasions found him to be honest, hard working and professional. He has proven he has the skills and ability to complete work to a high standard, on time and on budget. I was personally very impressed with Vincents "can-do" attitude, nothing was too big or too small and even when we got to humps in the road, he always came back with a solution to overcome the problem. We have many more projects in the pipeline for 2012 and wouldn't hesitate to work with Vincent again. Thanks Vincent for all your hard work!!

I've had the pleasure to work with Vincent Zhu for three years as my lead and mentor while working at eBench. During the time I worked at eBench, Vincent worked as my senior and team manager. His expertise in software development, database management and cloud architectures lead to the success of eBench as a software platform being able to compete against tech giants like Facebook and Instagram.

Vincent Zhu has been a great freelancer helping us to enhance the IP2Location Ruby project for many years. I like the way he handled the task given, precise and with passion. He always deliver solution on time and advise us the deficiencies that we were not aware of. Moreover, our IP2Location Ruby library has been used by many users and the quality of the library is of utmost importance. And, he never failed us in this matter.

The project proved to be much bigger and more time consuming than we had originally anticipated. Most of the problems were associated with the open source framework due to complex implementation on a complex product. Vincent manage to deliver a working model as per requirement despite the obvious greater investment in time than original estimates. More importantly though I have engaged him to do further work on the project to take the project to the next 2 stages.

Vincent was available right away and reasonable priced. He delivered the specified functionality on time and on budget. He was very prompt in responding to my requests, enhancements, and questions. He helped me clarify my requirements as a first time freelancer user. Overall a very pleasant experience.

I've had the privilege of working alongside Vincent in two companies. He was my direct manager. His management skills go hand in hand with his excellent technical capabilities. His leadership & technical know how had an immense impact on the overall design and implementation of many projects we did together. He excels at supervising, guiding and motivating other members of the team. I can honestly say that he is a natural leader, and is cooperative and helpful with anything that the team needs.

Incredible developer. I ran late on the information at times but communicated very well and followed up everything perfectly. Amazing developer! 5 stars is not enough!!!

Vincent's intellectual and technical talents have been recognised consistently throughout his career. Precise, efficient and enthusiastic.

I highly recommend zhu1230 (Vincent)! My experience with him on my second project has confirmed that he is a consummate professional - he is very responsive and receptive to feedback, fully committed to delivering a great outcome / product and has a quick turnaround time.

Vincent is capable, responsive, and takes initiative. He's highly skilled and a very good developer. I'd highly recommend him for small and large projects, his leadership skills and technical abilities are very strong.

Great communication and response times. Good understanding of ruby on rails framework.

Vincent has successfully finished another project for us. This time he proved to be both competent and patient (the delay on conclusion was not his fault). And he has been very helpful as usual. He is a good and reliable professional and we intend to keep working with him.

Impressive work according to agreement with minimum friction to my project is the reason why I keep choosing Vincent for Software Development tasks.

Excellent work !! very trust worthy and does the job lightening fast.. I recommend him strongly for whoever is looking for a serious and powerful coder.

Excellent communication and quality of work. I've worked with Zhu many times already and I've never been disappointed. Honest, reliable, and hardworking...can't ask for anything more! Thanks!!

The best aspect about Vincent's work was his quick communication. At times, and often due to circumstances outside my control, I could offer him no guidance or feedback. He kept courteous and friendly. I had some issues with the quality of work and the solutions that were implemented, but I admit my demands are the strongest in the business. With a less problematic client (due to reorganisations) our project could have gone a lot smoother.
