ABOUT

I'm a senior full stack engineer with over 9 years of experience building scalable and reliable SaSS enterprise applications serving thousands of monthly users. I have worked in several industries such as Healthcare, automobile, aviation, real state, change management and more. My most recent major work has been at LaunchpadLab where I was the lead developer building a green-field healthcare application which main purpose was decrease caretaker incident reports by 40%. As a lead developer my main responsabilities were working cross-functionally with the design and product teams to make sure we were hitting all the SOW items we said we were going to build as well as communicating directly with the clients, stakeholders ur progress, our challenges, our solutions and most importantly building trust and making sure the client relatioship stayed always healthy for future engagements. In this experience, I was also responsable of the performance of the development team. I developed our CD/CI pipelines with github actions, AWS pipelines to unblock speed as well as making sure our development cycle was well-oiled so that we were always hitting our milestones and tasks assigned. In my over 9 years of experience I have both joined already stablished codebases as well as build green-field applications from concept to production. My tech stack specializes in Ruby on Rails, nodeJS and Python for the backend and reactJS, vueJS for the frontend. I'm not a devOps person however I have owned the implementation of AWS infrastructure with EC2 and RDS for applications that needed to go to market quickly.

In the past, I've had the opportunity to develop software across a variety of industries such as Marketing Agencies , Healthcare Industry , Change Management , Real State , etc.

When I'm not at the computer, I'm usually rock climbing, experimenting with photography, or exploring the city on my bike.
