Happy Client
Trusted by many clients
What an excellent developer! He quickly grasped the code base of an existing Rails project and learned our proprietary framework with impressive speed. He resolved all the bugs within just a few days and implemented new features with exceptional quality. His proactive suggestions were targeted and valuable. We will certainly collaborate with him again in the near future.

Hendra is truly a talented developer. He was able to take a very messy stack and turn things around very efficiently and professionally. I would highly recommend him for RoR or anything within his core competencies. Thank you Hendra!

Hendra was an EXCELLENT fit for my particular job. We needed someone who had OAuth experience in relation to setting up an actual OAuth provider. I went through 2 or 3 freelancers who thought they could do it but nobody could really deliver until I met Hendra. His written English was much better than his spoken English, but between texting, phone calls, and screen shots, we were able to get the job done 100% to my satisfaction. He was very good with deadlines, ALWAYS available when he said he would be, and just great with communication and keeping his word in every respect.
I would highly recommend Hendra for any job related to Linux, Rails, web development, etc. etc. Some issues came up that were related to some tricky gem management/ RVM issues and he was very knowledgeable and helpful in troubleshooting them. All of this may be a bit "T.M.I.", but I'm sharing this to illustrate the point that this guy is very experienced, very nimble, and a very reliable person to work with .
Five stars plus.
