I've already written my own database and validation classes which are featured on famous web development and design blogs. I can definitely handle this.
Security is crucial part of any project but non of the developers around here are aware of it, please consider more about the security aspect of your project too. I'm a security analyst for last 3 years and it will help me to build you a secure solution against latest security threats. Dealing with sessions, file uploads, database queries, this must include security measure or else you are going to get into trouble.
I'm a 6 year experienced developer with international awards for mobile and web development. I can get this done for you. To be honest, The low bidding price is due to me being new to freelancer I'm looking to build up my client base, if you can, please be kind to reward me this project as it helps me to grow on freelancer and in return i will make sure you get the best solution.
Thank you.
