Finished MSc degree at IST in 2009 and immediately after (2010) joined Cerena research center. There conducted research and development in several fields of mathematics applied to geosciences and released open-source software such as Fillworks, ECMWF parser and GEOMS2. In 2014 became Assistant Lecturer for two MSc level courses at IST and by 2016 joined Geovariances as Software Engineer. During the course of almost 4 years, has developed UncerTZ/Isatis.neo Petroleum, as well as designed its brand and visual communication. More recently, in 2019, joined Eyeware as UI\UX Consultant for which it builds end user products related to gaze tracking using volumetric video. Independently it has developed several free Educational Apps for Android and frequently releases online publications and software.

I’ve produced desktop software in several scientific fields, both commercial and open-source. Further I’ve developed several educational apps for Android (free models in mobile equipments).
GazeSense - Performed functions on the level of architecture, core technology, UX\UI, and graphical design. GazeSense is a software specialized in unassisted gaze tracking.
Isatis.neo - It developed tools for this and other software solutions in Geovariances. Isatis.neo and other Geovariances products use geostatistics to perform spatial estimation in several sectors related to spatial imaging, namely Oil & Gas, Mining, Environment, Hydrogeology, Contamination, etc.
UncerTZ/Isatis.neo Petroleum - As part of a research and development consortium a time to depth conversion software was developed, later added as the Oil & Gas oriented edition of Isatis.neo. This software uses geostatistics, among other techniques, to perform a series of operations regarding the fields of Geophysics and Reservoir Engineering.
GEOMS2 - A Geostatistics and Geosciences modeling software. Mostly written in Python (some algorithms in C/C++), its fully equipped with a 3D viewer (Mayavi), 2D plots (matplotlib) and several numerical features for estimation, simulation, data analysis, and modeling. It was developed to replace software like the historical Geoms and GSI Student Toolbox (only the latter developed by me). This project was made within Cerena research center as support to research and education.
ECMWF parser - This software was developed to support the research and development conducted by Cerena research center in the ESA project Desertwatch. This project aimed to develop of an EO-based Information System to support national and regional authorities in reporting to the UNCCD and monitoring desertification trends over time. The software itself computed, visualized, and estimated (downscaling operations) important risk factors maps from the ECMWF reanalysis data. Other smaller toolbox were built within the same project such as ANA parser.
Fillworks - Fillworks was developed to support a consultancy project regarding the construction of a railway line in New Guinea. It provides visualization, drawing and calculation of fill and cut areas (to extrapolated volumes) given topography. This quantification of different railway scenarios provided a first measure of cost prior to further developments in construction. Latter it was used for educational purposes.
dAnalytics - Small tool built specifically for educational purposes in data analysis, specifically discriminant analysis, allowing the student to quickly make experiments in a GUI supported environment.
- The Math Adventures of Oscar - basic math casual game with several modes with the purpose of providing exercises in different operations. (given some changes in google policies this game requires some updates prior to be put in the store. I’m currently in the process of doing so.)
- The Algebra Adventures of Oscar - a game with exercises a bit more complex than the previous showing directly mathematical formula for progression in algebra skills.
- The Number Adventures of Oscar - a visual approach to mathematical operations like multiplication and division.
- The Puzzle Adventures of Oscar - a casual puzzle game played by dragging pieces to the correct position.
- The Time Adventures of Oscar - a game with exercises on learning how to check the time.
I’ve worked in a research center (in geosciences), as university assistant lecturer, as a software engineer in a company which develops software for scientific purposes, and UX Consultant in software for gaze tracking. I’ve also, at some point, started my own endeavour (with a friend) in building a company to produce digital products for education.
Consultant (UI\Software Engineering) (Eyeware, Switzerland)
Based in Lisbon. Started working for Eyeware in September, 2019. It is part of my functions to further develop Eyeware products, namely the UI\UX for GazeSense. On the course of my stay at Eyeware I’ve:
- Designed a workflow to perform gaze tracking in the Retail sector.
- Designed the 3d visualization engine (OpenGL bases) powering GazeSense scene builder and viewer.
- Contributed to the development of the core gaze tracking technology.
- Refactored Eyeware products using solid programming and UX patterns.
- Built and designed a new product line for desktop based gaze tracking.

Scientific Publications, eBooks, and Video Tutorials
- Modelação e Estimação – Uma introdução à Geoestatística (2010) (en: Modeling and Estimation - An introduction to Geostatistics) - This was a publication made to support Geostatics students at IST. It was originally released as a free e-book to numist student association which me and a group of colleagues had just founded. However I’m linking some other repository because the original seems to be down.
- Introdução à programação Parte I -Octave (2010) (en: Introducation to Programming: Octave)- A publication made to explain programming concepts and data analysis using programming language Octave. It’s written in Portuguese.
- Introdução à programação Parte II -Python (2011) (en: Introduction to Programming: Python (2011))- A publication made to explain programming concepts, data analysis, UI development, and scientific visualization using programming language Python plus a number of external libraries (numpy, scipy, matplotlib, wxwidgets, etc.). It’s written in Portuguese.
- Introdução à programação – Parte 3 - SAGE (2011) (en: Introduction to Programming: Sage) - A publication made to explain programming concepts and data analysis using programming language Sage. It’s written in Portuguese.
- Introduction to Python - This is a series of video tutorials about the basics of Python Programming. Originially these were part of a ShowMeDo kind of project for which I colaborated with. When that repository went offline another youtube user upload the videos which I’m linking (with my consent). Spoken in Portuguese.
- Introduction to Python and Matplotlib - This is a series of video tutorials about Python Programming, specifically using visualization library matplotlib.

Spoken in Portuguese.
- Learning Game: The Math Adventures of Oscar (2015) - The game was developed to train memory and mathematical reasoning of children in the ages of 5 to 9 and was largely adapted from the concept of casual gaming, typically a kind of game with a small amount of required commitment where the game-play is extremely intuitive and it has a “just to pass the time” state of mind. This article documents the development and the chosen method of commercialization for this game.
- An introduction to “collective publishing” (2014) - Considering the current state of communication technology this article hopes to expose a new concept, henceforth called “collective publishing”, which allows users to create their own journals and magazines without the need for sophisticated and highly proficient teams and software.
- Natural Fracture Networks (2009) - This is actually the extended abstract version of my thesis. It was reviewed by juri but it was never published in journal.

I’ve used mostly vector graphics for a number of tasks related to branding, marketing, aesthetics, user experience, and art. You can check my Behance profile for a better experience in analyzing graphical material (only some of the projects are present in Behance).
Branding and Logos
From left to right the logos of GEOMS2 (2013), anteia (2015), UncerTZ consortium (2016), Kartotrak (2018; “flat” style modification of a logo not originally designed by me), Isatis.neo (2018; release 2019). The order is cronological. All of the projects were made with vectorial graphics. My software of choice to do so is Inkscape.
I’ve made a number of icons in the past for multiple projects. These are general purpose examples:
And some other examples made in isometric style:
More recently I’ve prepared the icon set for the upcomming software Isatis.neo. This required the creation of images that described abstract operations. For this effect I’ve conceptualized a style which took hints from technical drawing and started making experiments with shades of yellow and orange as representative color. Here are some of the prototypes (some were eventually accepted for the final product):
You can see a better presentation of this project in my Behance profile.
Although not an area for which I have a lot of experience I did design and develop a number of graphical products marketing related.
This flyer was developed as a two sided foldable, one side being of scientific nature (a poster in an international conference), the other corporate.
You can see a better presentation of these projects in my Behance profile.
I’ve published a number of works in international conferences and a few educational projects.
The following is a static image of the poster A Case Study Of A New Time-Depth Conversion Workflow Designed For Optimizing Recovery presented at ECMOR XVI - 16th European Conference on the Mathematics of Oil Recovery.
The following is a static image of the poster Proper Systemic Knowledge of Reservoir Volume Uncertainties in Depth Conversion presented at Closing the Gap III - Advances in Applied Geomodeling for Hydrocarbon Reservoirs.
Game Art and Animation
These screenshots are from a demo presented to a book publisher in Lisbon that specialized manuals for the Portuguese language:
These screenshots are from a demo made to be presented to an university hospital in Lisbon:
This is a built set of screenshots from the proof of concept of a point and click game which had a lot of vectorial art with sprite and programatic animation.
Finally here is an example of some of the art for the series of “Oscar” games (a cat) which includes one of the release titles and one that was being prepared when we finally decided to end anteia:
I’ve made quite a few new widgets using UI library Qt. I’ve also designed experiences in small video games (using game engines) and workflows for scientific operations (desktop).
This section serves to provide examples of some widgets I made either in prototypes or for production. All of them were implemented in Qt (either directly in C++ or Python for the prototypes, eg PyQt or PySide).
This is an implementation I made in Qt for a switch button very tipical in mobile OS:
The project actually associated with another to create a kind of toggle button that accepts external widgets. This was created to great simplify the process of defining the inputs of an operation that relies heavily on multiple parameters. You’ll notice that some other customized widgets made to further improve the experience.
The following images are from a prototype to multi-select variables from a file (in our case a type of object that can have other types of objects with different categories):
This final example is the prototype implementation of a Ribbon alike widget in the Qt framework:
This project took some experimentation also to deal with re-sizing the ribbon:
I’ve recently produced the promo video for Isatis.neo software.
Musical composition and Songwriting
For a better presentation you can check all tracks in my Soundcloud profile.
A Procura (The Search) - This was an early sketch of a music for a video game (a kind of point and click crime novel) that was never finished. This is the type of music made to be played in loop (thus the repetition). It was made to give a sense of investigation, mystery, a searching for answers.
WALF - Tema Principal (Main Theme) - This was an early sketch of a music for a video game (a kind of point and click crime novel) that was never finished. This particular track was made to be played in the main menu.
Sozinho na tua cor (Alone in your color) - Songwriting in my university days, when social/ethical activism was a daily routine (released under the pseudonym Duarte Remna). It speaks about isolation, loneliness, indinference and prejudice.
Nova Terra (New Land) - Songwriting in my university days, when social/ethical activism was a daily routine (released under the pseudonym Duarte Remna). It speaks about unfair treatment given to immigrants.
