About

After building and leading comprehensive security programs at Skype, Microsoft, Skyscanner and Miro, I have now founded Ascensis.io to provide strategic cybersecurity leadership to organizations seeking enterprise-grade security expertise right-sized for their growth stage. My journey spans both offensive security and building enterprise defense programs, giving me a unique dual perspective that enhances threat anticipation while designing practical security solutions. I partner with technology companies, startups, and high-growth scale-ups to develop and execute pragmatic security strategies across critical domains: - Product Security & Secure SDLC implementation - Cloud Security architecture and governance - Detection & Response program development - AI Security and implementation Throughout my career, I've built security practices from the ground up—establishing teams, processes, and technologies that scale with business needs. I've also created custom security automation tools and contributed to open source security projects that are still actively used today. For startups and scale-ups, I bring Fortune 500 security leadership with implementation approaches tailored to your growth stage. My flexible engagement model ensures you build security foundations that support rather than hinder your rapid growth trajectory. Currently accepting select engagements with organizations looking to strengthen their security posture or navigate complex security transformations and growth milestones. While headquartered in Barcelona, Ascensis operates on a remote-first model, serving clients globally with particular focus on the European market.
