Developer.
Leader. Founder.
I'm Tiago Sampaio — a Technical Lead and Adobe Certified Expert in Magento 2 / Adobe Commerce, based in Brazil and working globally for over 15 years in technology and e-commerce.
Currently I lead development at Classy Llama — one of the most respected Magento agencies in the US — while also running MagedIn Technology, the company I founded in 2016 to build world-class Magento extensions and consulting.
Before going global, I spent 5+ years at B2W Digital— Brazil's largest e-commerce group (Americanas, Submarino, Shoptime) — rising from Solution Architect to Technology Manager. I left a management role to return to what I'm truly made for: hands-on engineering and solving hard problems.
Certifications
Languages
"I believe in following your heart and doing what you're truly made for. For me, that's solving hard problems and crafting commerce systems that scale."
Performance First
Every millisecond counts. I build systems optimized from the database query up to the CDN edge.
Built to Scale
Architecture decisions made today should still serve you at 10x traffic tomorrow.
Composition over Complexity
Clean, modular code that teams can understand, extend, and maintain — not clever code that breaks.
Business-aware Engineering
I speak both tech and boardroom. Solutions are measured by business outcomes, not just code quality.
15 years of
building things.
