TIAGO FERNANDES
Senior Frontend Engineer
I build interfaces that millions of people use every day.
About
With 8+ years shipping production applications across enterprise, e-commerce, and live-streaming, I specialize in building interfaces that are fast, accessible, and built to scale.
Currently at Dentsu, I lead the frontend for Enterprise Mobility — Alamo, National, Enterprise Rent-A-Car — serving millions of users monthly across the US.
I care about performance down to the millisecond, code that other developers enjoy reading, and design systems that don't fall apart at scale.

Approach
How I work
Performance First
Every millisecond matters. I optimize critical paths, split bundles strategically, and measure everything.
Clean Architecture
I write code that other developers enjoy reading. Component libraries that scale. Systems that don't break.
Async Communication
5+ years working remotely across time zones. I over-communicate, document decisions, and ship independently.

Let's build something great.
Currently open for remote opportunities with US and global teams.
