Projects in Colombia
The portfolio combines transactional products with content-led experiences. YuanCity supports imported-product discovery, purchasing, payment, and delivery; GreenCloset is a circular-fashion social marketplace with listings, chat, geolocation, and payments. Mikiguiki organizes movies, series, releases, and editorial detail pages in a streaming experience for web, iOS, and Android. TableChat brings AI-assisted menu browsing and ordering to the restaurant table. Allentown University centralizes its virtual campus, academic profiles, grades, library, and videoconferencing. Watti Energy presents and structures solar adoption for homes, businesses, and industrial clients through SolarFlex. The remaining work represents real notarial, agroindustrial, hospitality, social-impact, and cooperative operations through specialized websites rather than online stores.
Summary
In Colombia I built distinct digital products: a streaming platform, two marketplaces, a restaurant-ordering app, a university campus, corporate and institutional portals, and the digital transformation of a notary office. Each solution supports a specific operation and is presented through its real functionality.
Approach
Architecture was selected per product. Mobile and transactional platforms combined React Native, Next.js, Django REST, and PostgreSQL to separate catalog, users, content, orders, and administration. Corporate portals prioritized speed, editorial clarity, SEO, and content management. For Notaría Primera de Barranquilla, the website structures services, requirements, transparency, and official channels, while WhatsApp service was automated with a virtual assistant orchestrated in n8n and connected through Evolution API.
Outcomes
The result is a set of live products available across the web, App Store, and Google Play, with specific functionality for streaming content, buying and selling, restaurant ordering, studying, accessing institutional services, and automating citizen support. At Notaría Primera de Barranquilla, the combination of website, local SEO, Google Business Profile, and WhatsApp automation reached 58,000 verified visits over the last three months.
Highlights
- Two marketplaces: imported-product commerce in YuanCity and user-to-user circular fashion in GreenCloset.
- Original-film streaming with editorial catalog, rankings, releases, and mobile apps in Mikiguiki.
- Table-side restaurant ordering with a digital menu and AI assistance in TableChat.
- University campus with academic management, library, and videoconferencing in Allentown University.
- Solar-fintech web experience and no-upfront-investment commercial journey for Watti Energy.
- Notarial service automation with n8n, Evolution API, and 58,000 verified visits in three months.
Technical Decisions
These projects do not all share one architecture. Mikiguiki, YuanCity, GreenCloset, and TableChat require separate layers for indexable web experiences, mobile apps, authentication, catalogs or content, operational states, and app-store distribution. Next.js powers the web surfaces; React Native delivers mobile experiences; Django REST and PostgreSQL support users, content, orders, and administration where the product requires them. Mikiguiki structures films, series, rankings, and upcoming releases. YuanCity and GreenCloset implement different marketplace models: imported-product commerce and user-to-user circular fashion. TableChat focuses on digital menus and contactless ordering.
Empaquetadora del Norte, Watti Energy, Refinorte, Café Arduvi, Fundación Arduvi, and Cooagrovida have specialized goals. For Watti, I built the web architecture, SolarFlex communication, application journey, and presentation of residential, commercial, and industrial solutions. Across these portals, the technical priorities are clear information architecture, performance, accessibility, SEO, and manageable content. Allentown University adds an academic layer with student and faculty profiles, grades, a library, a virtual campus, and videoconferencing.
Notaría Primera de Barranquilla combines a public-service institutional website with operational automation. The site organizes deeds, civil registry, authentications, non-deed procedures, transparency, regulations, and citizen requests. WhatsApp service is connected through Evolution API and n8n, which orchestrates the virtual assistant and guidance workflows. The work also covers local SEO and Google Business Profile, whose metrics record 58,000 verified visits over the last three months.
