Senior Enginer/Developer

I am an Python/Golang/Elixir/Ruby programmer and Linux System Administrator. I had spent 22 years in the corporate world as a developer and linux administrator, working in the office. 8 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.

"Efrén did a phenomenal job with our GraphQL API server project. His Go code was implemented to specifications and in an idiomatic, scalable, and maintainable manner – our whole team had no issue understanding and adopting it into our codebase. Furthermore, his work ethic and communications were professional and prompt. We'd highly recommend Efrén and will certainly be considering him for future projects ourselves."
