A restaurant chain that donates money to Feed My Starving Children (FMSC) for every meal sold. I worked on their in-house Ruby on Rails system that gathers all the information generated in all stores converting them into useful reports for shareholders and providing functionalities for employees and store leaders. The biggest challenge was to migrate their point-of-sale (POS) system from Aloha to Brink while integrating other third-party services like 7shifts or designing and implementing certain features that store leaders needed daily.

A multi-tenant student management software for Christian, Montessori, K-12, private, and home schools. I worked on fixing existing bugs and implementing new features for the upcoming product versions, such as payments with credit cards and bank transfers.

A sales platform that helps users boost their company sales via smart tracking, communication, and metrics. I worked on bringing their platform to mobile stores using React Native while managing maintenance iterations on their Next.js web platform.

A mobile application that aims to help people with gut health problems by collecting data and analyzing patterns in order to choose the correct programs and guidance for every individual patient. I worked as a React Native developer on SANNO and was in charge of designing and implementing the whole CI/CD infrastructure, which involves:

• Automatic deployment to the stores
• Running end-to-end tests
• Vulnerability checks

An organization that helps animal shelters and people who want to adopt a new pet connect. I took the team leader role while helping develop the whole solution, including the back end, infrastructure, web admin, and mobile applications.

A system that finds and connects qualified applicants with managers. I worked as a back-end developer with Ruby on Rails and Elasticsearch, tuning the "under the hood" algorithm that matched qualified applicants with managers.

A web application that gathers all the apparel found in top brands and, through a smart search engine, helps users save a lot of time on shopping. I worked on designing and implementing the whole intake and search engine process using web crawlers, AWS, and Ruby on Rails with Elasticsearch and Kibana. Also, I helped my teammates on the front-end side with React by implementing small tasks.

Worked on creating a web admin on Ruby on Rails and DevOps solution using AWS to help Starshield Solutions migrate their old software with as little downtime as possible, given that they only had a 48-hour window to migrate their old software in the whole year.
