Staff Engineer delivering strategic improvements across platform scalability, security posture, and developer productivity. Proven expertise in architecting and leading complex initiatives, such as reducing critical vulnerabilities by 59% across 70+ services (CISO priority) and saving $500K+ annually via CI/CD optimization (Kubernetes). My impact bridges infrastructure and security domains, balancing robust system design with operational excellence and developer velocity. I am a passionate mentor dedicated to building high-performing teams and enabling engineers to lead independently.

Activities and interests

Travel: I like to explore new cities and countries, and I also enjoy trekking and hiking. I’ve been to the Annapurna base camp, so the next stop is Everest’s base camp.

Blogging: I love to blog about the technologies I use and learn at devdosvid.blog. Actively participate in technical communities as an AWS Community Builder and HashiCorp Ambassador.

Science: Fond of History, Astronomy, and Physics. I wish to see the Betelgeuse supernova explosion someday, even though the expected explosion date is between today and 100k years.
