About Me

Full-Stack & DevSecOps engineer building secure SaaS for real-world clients.

Senior Full-Stack & DevSecOps Engineer with 10+ years of experience building end-to-end products — from electronics and embedded systems to secure, observable SaaS/PaaS platforms in the cloud. Since 2019 I've been Co-founder & CTO at Nectios, working with enterprise clients including a major Latin-American bank, where I've led the design and operation of bank-grade infrastructure, security and compliance practices. I like to own the full lifecycle of a project — from idea and architecture to deployment, monitoring and feedback — keeping every technical decision aligned with business reality.
