What it is

The web platform of La fiesta del fútbol, the Primax x Listo campaign that raffled 7 double packages to an Ecuador match at the World Cup.

What it does

• I generated 12 million alphanumeric codes, each with its own QR code. Participants typed the code or scanned the QR to add it.
• At Primax stations, every $20 fill-up earned one code, and each code was one opportunity in the raffle.
• For Listo I set up the communication with their billing system, so purchases were known in real time and every $10 earned one opportunity.

How it is built

Laravel with Filament for the campaign setup and the metrics dashboards, and Vue with Inertia for the front end. Deployed on DigitalOcean, with a Cloudflare Turnstile check on the public form.

How it solves the problem

It scales with traffic, which mattered at about 203k users, and the campaign rules and metrics live in Filament instead of in code.

How I work on it

I did the whole flow myself: requirements analysis, choosing the technology and resources for the problem (full system design), development, deployment and maintenance, plus DNS configuration, transactional email and Sentry for error monitoring.

Role

Frontend Developer, plus maintenance of the Laravel backend

How it is built

A mobile-first PWA for loyalty-point redemption, built so it can be exported to native apps through React Native, with Expo, Tailwind CSS and API integration. I also maintain the Laravel backend, adding integrations and core functionality.

How it solves the problem

Customers redeem their points from any device. Working on both the interface and the backend integrations gives a seamless cross-device experience.

Role

Software Architect and Full-stack Developer (backend, frontend, infrastructure)

How it is built

A React Native app for Android and iOS. I defined the infrastructure and the key technical decisions for scalability and reliability, handled the deployments to the Play Store, the App Store and the backend, and built an admin panel for promotions and app settings.

How it solves the problem

Users browse and buy products, compare items with AI recommendations, locate nearby stores and securely store payment cards.

What it is

A seasonal Primax campaign, La Super Tanqueada del Año, where customers upload a photo of their fuel invoice to earn opportunities to win free fuel.

What it does

• The system detects the invoice data from the photo and awards the opportunities, so nobody types it in.
• The number of opportunities is variable: a campaign can boost a date, a fuel type and more.
• Each invoice must be $20 or more, and smaller ones cannot be added together.

How it is built

Laravel with Filament for the campaign configuration and the metrics dashboards, and Vue with Inertia for the front end. Deployed on DigitalOcean, with a Cloudflare Turnstile check on the entry form.

How it solves the problem

The platform scales with traffic, and the opportunity rules, such as boosting a date or a fuel type, are configured in Filament for each campaign instead of being rebuilt.

How I work on it

I did the whole flow myself: requirements analysis, choosing the technology and resources for the problem (full system design), development, deployment and maintenance, plus DNS configuration, transactional email and Sentry for error monitoring.

Role

Full-stack Developer: Laravel and Filament backend, Astro frontend

What it is

The website of the real-estate developer Casa Laguna, in Guayaquil, Ecuador. It shows the stages and the information of each house model, and it has landing pages for social media campaigns.

What it does

• It presents the development by stages (Floreana, Serena, Boscana, Florentina, Giardina, Pontiana, Paseo and Rincón), each with its models.
• Model pages show a photo gallery, price, construction area, room lists, a 360 tour and floor plans.
• Landing pages support the campaigns that run on social media.

How it is built

An Astro frontend with a React interactive island that showcases the housing stages and models, each stage with its own identity colour, styled with Tailwind CSS and animated with GSAP. The backend is Laravel with Filament, used to administer the content.

How it solves the problem

Faster load times and better search visibility, an interactive way to browse each housing stage and its models, and a panel to manage the content without touching code.

How I work on it

I did the whole flow myself: requirements analysis, choosing the technology and resources for the problem (full system design), development, deployment and maintenance, plus DNS configuration, transactional email and Sentry for error monitoring.

Role

Full-stack Developer

How it is built

A web platform for students and staff to reserve auditoriums, meeting rooms and labs, built with React, C#, IBM Db2 and Tailwind CSS, with API integration.

How it solves the problem

It reduces scheduling conflicts and optimizes resource management.

What it is

A registry of pre-selected small businesses that the public votes on, organised in four categories: Gourmet, Accesorios, Beauty and Hogar.

What it does

• Access credentials are generated on the fly and sent to each pre-selected business, for security.
• Each business registers its business and uploads its images, and gets a profile with logo, photo, description and links to Instagram and TikTok.
• Voters sign in with Google or Facebook, and a live ranking shows the votes for each category.

How it is built

Built with Laravel, Filament and Inertia with Vue. It is deployed on AWS with ECS and autoscaling, with CI on GitHub Actions, business images served from Amazon S3 and a Cloudflare Turnstile check on the public site.

How it solves the problem

It turns a category vote into a managed flow: only pre-selected businesses get access, voting goes through social sign-in with a bot check, the ranking updates live, and autoscaling adds capacity as traffic grows.

How I work on it

I did the whole flow myself: requirements analysis, choosing the technology and resources for the problem (full system design), development, deployment and maintenance, plus DNS configuration, transactional email and Sentry for error monitoring.

What it is

A platform open to the public where people register their short films following set guidelines, for the second edition of Festival de Cortos del Barrio ("Tu barrio, tu historia, tu cine").

What it does

• Participants sign up and register an individual or group entry that follows the guidelines.
• A jury from Banco de Guayaquil and ITV selects and reviews the entries, which is why the platform has a Filament panel.
• Public sections cover the key dates, the prizes, the finalists and the technical specs for the video files.

How it is built

Built with Laravel, Filament and Inertia with Vue. Filament gives the jury a review panel.

How it solves the problem

One place to register, check the rules and dates, and follow the festival, with the jury reviewing every entry in a single panel.

How I work on it

I did the whole flow myself: requirements analysis, choosing the technology and resources for the problem (full system design), development, deployment and maintenance, plus DNS configuration, transactional email and Sentry for error monitoring.
