Full-stack development from interface to infrastructure.

Web platform for managing and optimizing electricity contracts in Portugal. It aggregates all tariffs regulated by ERSE into a unified interface, allowing users to compare suppliers, simulate real contract costs, and identify the most suitable time-of-use plan and contracted power level based on their consumption profile.

The user uploads consumption data exported from E-Redes (XLSX with 15-minute granularity), which is analyzed locally in the browser—without being sent to external servers. Based on this data, the platform calculates detailed monthly estimates including IEC, DGEG, CAV, and VAT, and generates personalized recommendations on the most advantageous contract among those available on the market.

Website for a local taxi service based in Ponte de Lima, Portugal, offering airport transfers, local journeys and tours across the Minho region. Visitors can estimate the price of a trip in real time: the platform geocodes the pickup and destination locations, calculates the route on an interactive map and returns the expected distance, duration and fare.

The site is fully bilingual (Portuguese and English) and built for conversion, with direct contact through phone, WhatsApp and Messenger, plus a QR code that saves the driver's contact card straight to the customer's phone. It is completely prerendered as a static site, ensuring fast loading and strong SEO for local searches.

Browser-based image converter and editor where all processing runs locally through ImageMagick compiled to WebAssembly. Images never leave the device: conversion across 50+ formats (JPEG, PNG, WebP, AVIF, HEIC, JXL and more), resizing, cropping, color adjustments and one-click filters happen entirely client-side, with a live before and after comparison slider.

Batch jobs run in parallel on a pool of web workers sized to the device's CPU, downloading results as a zip. Export controls adapt to each format's quality model, with optional metadata stripping, and the app installs as a PWA that works fully offline.

The Cross-border observatory Rio Minho aims to respond to the challenge posed by the AECT Rio Minho of enhancing the economic, landscape, and heritage resources (both tangible and intangible) of the cross-border territory of Rio Minho.

Through a repository of statistics, reports, studies, and opinions on the dynamics of the endogenous resources of the cross-border Minho River territory, in collaboration with relevant public or private institutions or entities in the territory, it aims to create reliable and relevant data for the development of proposals for job creation, green mobility, population retention, among others.

The SINVAQUA platform is a system based on satellite remote sensing for supporting the early warning and rapid response to the introduction and dissemination of aquatic invasive exotic plants, taking the invasion by the water hyacinth (𝘌𝘪𝘤𝘩𝘩𝘰𝘳𝘯𝘪𝘢 𝘤𝘳𝘢𝘴𝘴𝘪𝘱𝘦𝘴) and the large-flowered waterweed (𝘌𝘨𝘦𝘳𝘪𝘢 𝘥𝘦𝘯𝘴𝘢) and as a proof-of-concept case study in two water courses located in northwest Portugal – Lima and Cávado rivers.

This is a Geographic Information Platform that makes it easy to plan routes along the National Road 2 in Portugal. With this website, you can create, share, and extract routes based on points of interest. These routes can then be used on other platforms that support KML file import, allowing for seamless integration with various mapping and navigation tools.

A geographic information system developed to manage soil samples collected in different geographic areas.
This platform includes an authentication system and an interface that allows the administration of users and samples. Soil samples can be visualized using geographic maps such as the World Database on Protected Areas (WDPA) and Corine Land Cover.

This is an educational App and it is part of an Erasmus+ project to raise awareness on climate change. Throughout the project, various issues related to biodiversity will be submitted. App users will be able to participate in the various quizzes available.
It has an entry page with a simple user registration, an intermediate page that directs subscribers to participate in the available quizzes or to the rankings of the different quizzes. It is fully educational and managed by teachers from 5 schools, Cyprus, Iceland, Finland and Portugal. It is part of an Erasmus+ program and aims to raise awareness in the community about environmental problems and the consequent climate change.
