    I am an Python/Ruby programmer and Linux System Administrator. I had spent 18 years in the corporate world as a developer and linux administrator, working in the office. four years ago I jump to working remotely from home as a freelance developer. I have built apps for my customers ranging from locally in Nueva Esparta, and all over the world. I take pride in my work and the majority of my customers bring me repeat business and referrals. I feel I have been successful, not just because of my web programming skills, but because I am a reliable and dependable web programmer that can be trusted to follow through with my work. I enjoy working directly with my clients, rather than having project managers involved. Even though I seldom meet my clients in person (due to geography), I am able to effectively communicate via email and chat to complete the website development project to their specifications.
