2020-2021 - FullStack Architect  @ Valyous

Valyous/Givers aim to connect doctors and patients in a way that allows to reduce appointment wait times from days or months to minutes while making sure the patient meets the doctor that most suits their needs. I joined Valyous/Givers in times of turmoil as Tech Lead and the VP RND left a few weeks after, so founders looked to me to pick up the slack until he is replaced. I acted as Tech Lead / Architect responsible for mentorship for the team to best practices, development process and deployment standards as well as establish good practices around feature design and tech design. The organization had to be HIPPA compliant, which meant that all decisions and architectures had to take this into consideration. The stack we used was Vue for desktop application and React Native for mobiles, NodeJS API server, a few SAAS providers like Twilio and Vonage as well as some AWS services. Since our clients use both desktop and mobile devices, we came up with an elegant solution that allowed us to introduce GraphQL into the stack for improved performance to mobile devices.
