Hello -
First, please note I am not from Indonesia. I am born and raised in the USA, and am working with Freelancer to correct the location error.
That said, I have many years experience in Ubuntu/Unix, and MySQL, Ruby on Rails, I worked for and was trained at Bell Labs in the 90s and have been working with Unix and SQL, databases supporting research, libraries, and web back-ends ever since.
However ,and I'm a new Freelancer.com user, I need to build a reputation to leverage this experience. To that end I've reviewed your project and am confident I can provide a great result for you at a substantial discount to the average bid you're receiving.
I look forward to completing the NDA and reviewing the code you've already developed to better understand the best path forward, including the potential to develop iOS and Android apps to help your site's users add and search location data and images, after your main site is completed.
Regards,
Kevin
