Jose Luis Pujante

As a Data Migration Engineer, I worked on analyzing and processing large-scale datasets (around 500 million data points) as part of a major platform migration project. I used a custom Python tool using Pandas and NumPy to handle data transformation and leveraged a cluster of virtual machines to process the data in parallel. My responsibilities included generating the data output for ingestion into the new platform, coordinating between technical and business teams, reporting issues and bugs, and ensuring data consistency throughout the testing phase before going live. This role required strong communication skills and a deep understanding of both data engineering and business operations to ensure a smooth and successful migration.

Skills: Software Architecture · Mobile Application Development · Spring Boot · FastAPI · PostgreSQL · Docker · Amazon Web Services (AWS)

As a Mobile App Developer, I was responsible for building a cross-platform application for iOS and Android using React Native. I led the design team and served as a key link between the frontend development team and business stakeholders, helping to define and prioritize new features and updates based on advisor feedback. I also managed the app’s deployment process across test and pre-production environments, using Apple TestFlight and Google Play Store distribution channels to ensure smooth testing and rollout.

As a Web Frontend Solutions Architect, I was responsible for analyzing requirements, designing solutions, and developing the architecture of frontend services for insurance clients, large enterprises, and External Support Providers (ESPs). The portals were built using AngularJS and designed as modular, reusable components to ensure scalability and consistency across multiple applications. The frontend architecture was integrated with a backend system based on OpenText. To enhance performance, I implemented a caching layer that significantly improved page and module load times, optimizing overall system responsiveness and user experience.

SATLAS is a project co-funded by the European Space Agency Advanced Research in Telecommunications Systems 3-4 SATCOM APPS programme.

The aim of SATMED is to improve public health in emerging and developing countries, most significantly in isolated areas with poor connectivity. SATMED enables communication between doctors, thus propagating the transfer and exchange of medical knowledge and supporting tools for medical e-learning and e-teaching. An IT cloud infrastructure accessible around the globe facilitates the data exchange between professionals and the setup of a medical infrastructure such as electronic medical records and tele-radiology systems. As a Software Developer, I collaborated directly with the Software Architect to design, build, and deploy core services and applications for the SATMED eHealth platform. This included tools such as a medical consultancy interface, video conferencing system, and cloud-based data services—designed to support healthcare professionals in remote and underserved regions. I was responsible for developing both frontend and backend components, ensuring smooth service integration and real-time communication across the platform. The tech stack included Java, Python, AngularJS, Bootstrap, Node.js, PostgreSQL, Celery, RabbitMQ, WebRTC, REST APIs, and WebSockets.

SASN, Service-Aware Support Node. Tool for traffic inspection in multi-vendor and multi-access networks. Its main applications are policy control and charging in mobile broadband networks. Tasks related to the design / development of the system configuration tool written in Perl. This tool is self-generated low-level configurations, systems and security policies of both the nodes that comprise the system as the switches that connect the computers that make up the cluster.
