Olleb // Log

I am a Senior Specialist Solutions Architect, university lecturer, and experienced private tutor with a strong passion for building resilient enterprise solutions using open-source technologies.

Professional Background

Throughout my career as a software engineer, consultant, and support engineer, I have maintained a strong customer-first mindset. This diverse experience has allowed me to support organizations worldwide, both remotely and on-site, while traveling extensively across Europe to deliver hands-on technical assistance. Today, I complement my enterprise work by speaking at leading industry conferences and events.

Academic & Teaching Experience

Alongside my industry career, I have developed graduate-level course materials for a Master's program in Data Science and taught programming courses for a Bachelor's degree in Computer and Telecommunications Engineering. I also design and deliver specialized university programs covering advanced DevSecOps practices.

Education & Research

I hold a Bachelor's degree in Computer Engineering from Universitat Rovira i Virgili, where I also earned a teaching qualification. I later completed two Master's degrees in Computer Engineering at Universitat Oberta de Catalunya.

My research-focused Master's thesis, published by RECERCAT, strengthened my scientific research skills. Driven by a lifelong passion for learning and a desire to better understand the relationship between people and technology, I am currently pursuing a degree in Psychology.


Workshops

In my role as a Senior Solutions Architect, I design tailored, hands-on workshops to meet the specific technical and strategic needs of enterprise clients.

These sessions deliver actionable skills and strategic insights to empower teams in an ever-evolving technological landscape. My core areas of expertise within the enterprise open-source ecosystem include:

  • Modern Application Development: Accelerating delivery and cloud-native practices.
  • Robust DevSecOps Methodologies: Securing the software supply chain from code to production.
  • Advanced Security & Identity: Enhancing environments through robust Single Sign-On (SSO) solutions.

Vulnerability Research & Disclosures

In addition to architectural design, I conduct security research with a strong focus on responsible vulnerability disclosure. Although the majority of my security assessments are carried out under enterprise NDAs or within private infrastructures, I consistently contribute to improving the security of open-source software through coordinated disclosure.

The following are publicly disclosed CVEs for which I have been officially credited as the discoverer and reporter:

  • CVE-2026-4981 | Red Hat Advanced Cluster Security (ACS) – Open Redirect & Content Spoofing in OAuth endpoint. – View CVE
