A fully functional restaurant and supplies store ordering system displays the company's product catalog with details and prices; it includes a shopping cart, a checkout process, and direct integrations with messaging apps using URL links.

As a developer, I liaised with a UI/UX designer to build an ordering system for restaurants and small businesses during the pandemic's lockdown. I was in charge of gathering the requirements and developing both the front end and back end. The app was a progressive web app to encourage users to download the app from their mobile browsers after first use.

An Android and iOS app built with React Native allows people in Cochabamba, Bolivia to query and search public transportation alternatives using a map. The project was initially built as a side project and later gained the attention of the state university with whom we joined forces and manage to include more routes to the geodatabase.

The project was built with the help of a UI/UX designer and a fellow front-end engineer. As the team lead, I was in charge of the mobile application architecture, building APIs and back-end services to consume geospatial data migrated into the PostGIS database from shapefiles.
The most challenging and exciting task was developing the spatial queries to efficiently determine the best bus route to take for getting from one place to another and make the computations available offline.

A web-based ERP and health information system for small- and mid-sized healthcare businesses, ranging from physiotherapy centers to small clinics and medical centers.

It manages patients and schedules times with each physician in different specialties. Also, it handles inventory, billing management, surgeries laboratories, and integrates the data with accounting.

As a founder, I played multiple roles where I interacted directly with the end-users and learned all their craft's specific knowledge.

As the main developer, I designed and developed the system for small businesses with an affordable and fully featured system to solve their needs.

The system was built with JavaScript as the core language used on the front end (with AngularJS at the beginning and React later) and Node.js for the back end. PostgreSQL powers the database.

This was a long project that evolved as new customers arrived with variants of the same need.

It is now available on a yearly subscription basis for customers in my country. All the infrastructure of the SaaS service is handled in AWS using RDBS service and EC2 Linux Instances.

An Ionic mobile and web app for Clinica Los Olivos S.A allows patients of the clinic to make an appointment with their favorite physicians by directly reserving a predefined space on the physician's agenda and integrating with the clinic's main system. The app is available for Android, iOS, and web.

As a full-stack engineer, I was in charge of developing both the mobile interface and the back-end APIs. The main goal was to integrate all of the appointment workflow transparently with the clinic's ERP system to enable real-time appointment scheduling with the physicians' agendas.
