Senior Backend & DevOps Developer on SwissID, a login and user management platform with qualified digital identities, integrated with 3rd parties such as Swiss Post.• implemented and deployed microservices to support qualified electronic signing and multi-tenant trust services for highly-certified authentication and authorization (e.g. OpenID Connect with Passkeys).

Developer & researcher on a time-series analysis, annotation and visualization platform.• developed a collaborative tool for HVAC time-series analysis, used by data scientists to annotate over raw data and to instruct machine learning models on how to detect and predict important data patterns (i.e. anomalies);• implemented a distributed system that stores and queries time-series data and annotations (Spring Boot server, InfluxDB, PostgreSQL, Docker Swarm), employing techniques and best practices (load-balancing, sharding and in-memory caching with Redis) in order to handle massive amounts of data with high cardinality;• implemented a frontend application (ReactJS, Redux, Typescript, LESS) that displays time-series and annotation data on a chart visualization, allowing data scientists to view, create and update annotations, as well as review changes made by others.

Distributed Systems Engineer on a fully-fledged platform for IoT sensor data processing, querying, notification and presentation.• developed a benchmark methodology for evaluation of Complex Event Processing technologies;• designed a distributed architecture where the platform, which receives stream data through MQTT,deploys messaging queues (RabbitMQ) and stream processing pipes (Spark, Flink, Ignite) inconcurrent pipelines, to deal with both continuous data and short bursts of data at a large scale.

Backend Developer and Mobile Developer at Ubiwhere, where I researched and used state-of-the-art tools and methodologies for backend, data processing and API design, and did mobile application development, project management and requirement analysis.• developed and deployed a business process modelling and integration platform (backend, message broker, frontend) that collects absences and check-ins/check-outs from University of Coimbra workers and automates user/group task assignment, periodic integrity checking, and email notifications;• developed iOS applications for various brands (Vodafone, Anacom, Prio, University of Porto).

Lead Distributed Systems Engineer, Backend Developer, Mobile Developer and UI/UX Designer on a mobile platform for challenge-sharing between users and brands, with real-time chatting and user event tracking and analytics. Much of the design behind YouClap was made by revising and reworking the common tropes of modern social media apps, so as to make judging of competition entries more impartial.• developed backend logic for the mobile apps, dealing with out-of-order logging, event sourcing, concurrency challenges and various optimizations (REST call chaining & caching, payload compression in low bandwidth connections, etc...);• lead the interaction design of the apps, supervising and unifying a vision of the core experience that properly handles multiple scenarios (video/photo resolution in different screen sizes and densities), creating interaction models, user task flows, mock-ups and UI specifications, and developing these in Android and iOS environments.

iOS Developer on a multiple-storyboard-single-codebase client for a bike-sharing product, deployed in multiple cities in North America. The infrastructure and its frontend clients were designed with performance and high-availability in mind, and comprehend a myriad of sub-systems that appear in heterogeneous but interconnected forms, such as Remote OSGi services, REST endpoints, distributed messaging queues, distributed & polyglot persistence, infrastructure auto-scaling in cloud-based environment, etc.

Backend Developer, Mobile Developer, UX Designer, Product Designer and Project Manager on a ride-sharing mobile application that allows users to find rides near them, schedule their own rides and chat in real-time. Over a span of 4 months since its official launch, Thumbeo reached over 600 registered users, 1200 published rides, 20 partnerships with various music festivals and radio stations in Portugal, and 1000 likes on Facebook. The app was featured by "SIC"​ (sic.pt), the second most-viewed TV channel in Portugal, "Pplware"​ (pplware.pt), the most popular Portuguese tech blog, and many other local newspapers, blogs and radio stations. In 2016 we were nominated for "Best use of technology" at the Iberian Festival Awards.• developed core functionality of an Android application;• devised the overall user experience of the final product;• designed a set of UI components and digital marketing assets;• established partnerships with representatives of music festivals, radio stations, student councils and other events and associations.

Developer on an biomedical information extraction software, used by researchers in the biomedical field to automatically extract dozens of heterogeneous biomedical concepts using state-of-the-art methods for Natural Language Processing (e.g., sentence splitting, tokenization, lemmatization, part-of-speech tagging, chunking and dependency parsing) and Concept Recognition (e.g., dictionaries and machine learning).• developed a backend infrastructure capable of deploying independent web services for concurrent annotation of biomedical documents, each service having their own set of ontologies and Machine Learning models;• redesigned the existing platform to support multi-language processing, using OpenNLP models, and exporting of annotations to multiple text corpora formats (A1, BioC, CoNLL, JSON, XML and Base64).
