Senior Mobile Software EngineerUmeDec 2024 - Current (1 year 7 months)As a Senior Mobile Engineer, I lead the development of the LUME platform — a scalable foundation designed to streamline the creation of new Flutter products for Ume. The goal is to enable teams to build and launch applications quickly, transparently, and with minimal setup. I architect modular code structures, reusable components, and robust tooling to accelerate development while maintaining consistency and quality across projects. My work on LUME significantly reduces time-to-market and empower teams with a clear, efficient app creation workflow.- Senior Mobile Software EngineerMottuOct 2024 - May 2025 (8 months)I played a key role in enhancing the Mottu App by implementing important improvements to the Flutter mobile application and adapting it for the Web platform. The web adaptation involved several technical challenges, such as integrating with JavaScript for browser-specific functionalities, handling routing safe, and ensuring compatibility by protecting the codebase against unsupported Flutter operations on the web (e.g., platform-specific APIs and packages). These efforts resulted in a unified, cross-platform experience and a more robust and maintainable codebase.

- IASAP-V: A privacy-preserving authentication and sybil detection protocol for VANETsInformation SciencesAug 2016TO APPEAR (Volume 372, 1 December 2016, Pages 208–224) Node authentication, non-repudiation and anonymous communication are key roles to provide security in Vehicular Ad Hoc Networks (VANETs). On the other hand, the trade-off between authentication/non-repudiation and anonymous communication may lead to a harmful type of network attack called sybil attack. In such an attack, a malicious node behaves as if it is a large number of nodes. In this paper, we propose an anonymous authentication and sybil attack detection protocol for VANETs called ASAP-V. Experimental results suggest that ASAP-V is more robust against sybil attacks, with lower average detection time than the state-of-art works, also without false-positive and false-negative detec
- IMultilevel Security in UPnP Networks for Pervasive EnvironmentsIEEE Transaction on Consumer ElectronicsFeb 2013Security has become a critical concern in pervasive environments, since personal information can be available to malicious users. In this context, some of the major drawbacks in UPnP architecture are the user authentication and service access control, which are not suitable for pervasive environments. Moreover, the inherited heterogeneity of pervasive environments brings different security and privacy requirement concerns depending on the environment and the services provided. This paper introduces a UPnP extension that not only allows multilevel user authentication for pervasive UPnP services, but also provides a flexible security approach that adapts to the network. What is more, it offers a seamless security level negotiation protocol.
- UTowards the UPnP-UP: Enabling User Profile to Support Customized Services in UPnP NetworksUBICOMM Proceedings of the The Second International Conference on Mobile Ubiquitous Computing Systems Services and TechnologiesOct 2008In a nutshell, UPnP aims to enable simple and robust connectivity among consumer electronics, intelligent appliances and mobile devices from many different vendors. Nowadays, it is getting an increasing popularity due to its robust way of connecting devices and the massive number of already developed applications, complementing the useful new era of pervasive computing. Although UPnP is an easy-to-use solution for discovery, which allows controlled devices to share and access users contents, it does neither provide user authentication nor authorization mechanisms, requirements that would require user's data on personal profiles. As a consequence, we propose an extension of the UPnP protocol called UPnP-UP, which allows user authentication a
- IAn Open-Source Component-Based Toolkit to Support E-learning Multimedia EnvironmentsICSNC the Second International Conference on Systems and Networks Communications IEEE Computer SocietyAug 2007In the Distributed Systems area, the number of Multimedia Applications has increased due to fact that it provides a better integration among their users, as well as being recognized as an essential distinctive feature for e-learning environments. However, most of the existing e-learning solutions are not open-source and are not designed with extensibility in mind, making integration with other systems difficult. In this way, this paper proposes an open-source component-based toolkit to support e-learning multimedia environments called ArCoLIVE, which offers real time multimedia services for e-learning systems.
- IA Privacy-Preserving Authentication and Sybil Detection Protocol for Vehicular Ad Hoc NetworksIEEE International Conference on Consumer Electronics ICCE T Network TechnologyIn vehicular ad hoc networks (VANETs), the trade-off between privacy and authentication leads to a harmful type of network attack called Sybil attack. The challenging is to avoid and detect such attack without compromising user (vehicle) privacy. Thus, this paper proposes a privacy-preserving authentication and Sybil detection protocol for VANETs.
