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.

I am a full-stack web developer with a special interest in Ruby on Rails. Test-driven development is at the core of all advanced web applications that I create in order to allow scalability. I'm also experienced in JavaScript and its frameworks, including Angular, and React. I started out my journey by pursuing a degree in Computer Security and Forensics. Throughout my first year of that, I developed a passion for code. I was introduced to markup and the basics at a young age but during my first year of college is when I really started to code with more advanced programming languages. In a college environment, it's not easy focusing solely on programming due to the many unrelated subjects required for obtaining a degree. After realizing what I really wanted to focus on was web development, I decided to switch gears. One year into that degree, I took an alternate route and attended Bloc where I was able to dive deep into web development as a whole and really understand each and every concept. Not only did I learn the prevalent technologies and languages at a high level, but I also acquired the skills to continue learning on my own. I'm hardworking, self-driven, and I develop end-products that my clients are beyond happy with.
