Miguel plans and implements full-stack solutions, focusing on solving problems and maximizing users' and other stakeholders' value through a pragmatic and technology-agnostic approach. He leans into his scientific research background, where he developed complex systems such as robotic simulation platforms and distributed computing systems, to learn and apply new technologies quickly.



Preferred Environment

Amazon Web Services (AWS), JetBrains, Git, MacOS

The most amazing...

...project I've worked on is designing and developing the hardware, software, and artificial intelligence for a real-world swarm robotics system.

Work Experience


2017 - PRESENT
Care & Family Health
  • Acted as the main full-stack developer for the company since its inception. Responsible for the backend, the frontend, and DevOps.
  • Implemented security- and privacy-focused solutions due to the sensitive nature of the data (PHI), with encryption at rest and transit throughout the system's different components.
  • Setup and integrated infrastructure using AWS, focusing on ECS, S3, DynamoDB, SNS, and SQS.
  • Managed a small team of developers and was responsible for major technological decisions across all projects.
  • Guaranteed scalability of the system for thousands of users while optimizing the infrastructure resource usage.
  • Integrated with multiple third-parties, such as payment gateways (Stripe), governmental institutions (Ontario Ministry of Health and Long-Term Care), and communications providers (Stripe, RingCentral).
  • Implemented fully-featured telemedicine capability into the system, where patients can have video appointments with a practitioner.
  • Introduced continuous improvements and automations to make the system more efficient for the users. An example is the use of OCR to handle documents with minimal human intervention.
Technologies: Amazon Web Services (AWS), Express.js, Redux, Travis CI, Docker, React, Node.js

Full-stack Developer

2016 - 2017
Kaja (via Toptal)
  • Developed an intelligent itinerary planner that takes into account multiple variables, such as the users' preferences, point-of-interest properties (location, rating, category, and so on) using machine learning techniques such as spatial clustering and genetic algorithms.
  • Developed a recommender system for events based on the users' Facebook liked pages. The system further cross-referenced the Facebook data with Last.fm's API in order to discern musical tastes.
  • Added i18n to the product (both static and dynamic elements) using Microsoft Azure's Cognitive Services for automatic cached content translation.
  • Implemented a customized itinerary viewer with Google Maps.
  • Developed custom map overlays and integrated with the Directions API with client-side caching.
  • Handled the complete redesign/rebranding of the website.
Technologies: Java, AngularJS, PHP, Node.js

JBotEvolver is a Java-based open-source and versatile simulation platform for education and research-driven experiments in evolutionary robotics (ER). JBotEvolver has been used in previous ER studies of our research group: in offline evolution to online evolution and learning, single to multi-robot systems, and in a number of undergraduate and graduate courses at the University Institute of Lisbon (ISCTE-IUL).


Conillon is a lightweight distributed computing platform. It allows Java-based tasks to be computed on a grid of computers with minimal effort and overhead. The necessary Java classes are loaded by worker nodes as needed.

A Sea of Robots

Winner of the "Best Robot Video" at the video competition held yearly by the AAAI international conference.

Color Orbs

A game for Windows Phone that tests the player's memory and reaction speed. The player has to click colored spheres in the correct order and can also use power-ups to make the task easier. Color Orbs received the first prize in the Windows Phone App Code Camp competition.


Jhip8 is a Chip-8 interpreter written in Java and was intended as a first experiment in the world of emulation. The project implements all the opcodes and features with the exception of sound.


This is a JavaScript port of Jhip8 and the working version can be found here at the link below.
