    I have been developing web-based B2B and B2C applications in Python for the last 6 years. I have helped and guided dozens of clients to design, develop and deploy applications for their business requirements. I'm here because I have some free time these days, and would like to work on relatively smaller projects. So if you're looking for an experienced Python developer, hit me up. Even if we don't end up working together, I love talking about web-technologies. If you are reading this, the chances are you'll be having issues which I could help with. So feel free to touch base with me. Thank you.
