At IEE, I replaced paper and Excel processes with two internal web apps: a 90-question certification audit and a legal case-file tracker. I designed their UI, workflows, and data model, then migrated historical data into a single SQL Server database.
At CommunityLab, I shipped a production MVP where companies describe eight business areas and receive an AI-generated diagnosis and improvement project. I also implemented percentage-based matching between experts and projects.
At Play Lab, I built the Django REST Framework API for an English-learning app that calculated student levels from answers in interactive games. I added progress KPI endpoints for dashboards and personalized content, secured with JWT authentication.
At Primal, I migrated a funding platform for Amazon environmental projects to React and Django REST, building its contributions API from scratch. I also integrated payments for contributions under $500 MXN, Google OAuth2 login, and a Google Maps view of the project zone.
