    As the Managing Director of Vigilant Cyber Ltd., I lead a team of dedicated cybersecurity professionals committed to safeguarding businesses in an increasingly complex digital landscape. We understand that cybersecurity is not just about technology; it's about building trust and ensuring business continuity. That's why we've established ourselves as a premier provider of comprehensive cybersecurity solutions, leveraging strategic partnerships as a Kaseya Gold Partner, Sophos CSP and MSP, and Microsoft CSP. My journey into cybersecurity is deeply personal. In 2017, I was a victim of identity theft. This experience was a stark wake-up call, demonstrating the devastating impact of cybercrime and the critical need for robust digital defences. Rather than allowing this experience to define me, I chose to channel it into a driving force, pivoting my career towards cybersecurity.

    I'm Tech Lead and System Architect at Net Reply, where I'm currently focused on designing and developing xApps and rApps in the O-RAN domain. Before joining Net Reply, I worked as a Principal Researcher at Samsung Research in London. There, I contributed to the development of the 6G architecture, applying my expertise in 5G/6G networks, multi-access edge computing, and network softwarisation. I particularly enjoy modelling networks using combinatorial optimisation techniques, integrating AI/ML algorithms into networking, and creating advanced network management systems. Earlier in my career, I was a Research Engineer at Bosch, focusing on edge computing for 6G networks. I also worked as a Researcher at Fondazione Bruno Kessler (FBK) in Italy, where I concentrated on zero-touch network and service management at the edge of 5G networks. I earned my PhD in Computer Systems Networking and Telecommunications from Alma Mater Studiorum - Università di Bologna, co-tutored by FBK. During my PhD, I had the opportunity to spend six months as a Visiting Researcher at RISE Research Institutes of Sweden. Throughout my career, I have published several papers in prestigious conferences and journals, and I hold multiple certifications in networking. I am passionate, self-motivated, and enthusiastic about my work. I enjoy coming up with creative solutions to complex problems and collaborating with others to advance ideas.

    Technology has been a passion of mine since childhood. Growing up in Macau, I was captivated by computers, often taking mine to repair shops—not just to fix it, but to learn how they worked. This curiosity turned into a career in IT, where I’ve spent over 15 years solving tech problems professionally. Beyond IT, my background in Music Production (BA) and Psychology & Hypnotherapy has strengthened my ability to communicate well and clearly, provide client-centered solutions, and support creative professionals with music software, studio setups, and workflow optimization. I specialize in IT support for businesses, non-profits and individuals, just about anyone in need of some IT help, networking with people of different strengths, sharing knowledge, offering remote and on-site troubleshooting, system administration, hardware & software solutions, networking, data recovery, consulting and more. Having lived in Angola, Macau, and the UK, I bring a global perspective, adaptability, and a personal client-first approach to my work.
