About Me

"Knowing that my work will impact a lot of people and therefore I must do my best to make their work easier." is the greatest quote that I guide myself with. I'm a Full stack engineer - I like to do everything in relation to the system, an API Builder - I like to create api to release data securely and a Data Processor - I like to process a large amount of data and make some SQL optimization. I have a large experience working in teams and being a team lead, so I like to teach as much as I like to learn new things. I'm a proactive person that can find solutions before you even knew you had a problem because I like to focus on innovation and thinking outside the box.<br>My best motivation is to see and compare results, showing how much my software can optimize time and increase my clients' billing.<br>
