THE STORY
Juliana’s Path To Senior
- 01
Juliana got laid off from her junior frontend job. Most people panic and apply to two hundred positions. She didn't.
- 02
She rebuilt from zero: data structures and algorithms, the event loop, TypeScript, testing. The gaps every self-taught path leaves behind.
- 03
Then she learned to think and talk like a senior: frontend system design, architecture decisions, owning the technical conversation.
- 04
She came back as a founding senior frontend engineer. Making about five times more. Read that again.

IN JULIANA’S WORDS
“I went from a junior front-end developer that was laid off to a founding senior front end engineer and making about five times more.”
THE SENIOR JOURNEY
The senior skills Juliana built
Getting to senior isn’t about learning another framework. Juliana’s path covered the dimensions that actually move an engineer up a level — the same areas theSeniorDev coaches every member through:
System Design & Frontend System Design
Juliana learned to lead system design and frontend system design discussions — scalability, data flow, and architecture trade-offs — the conversations that separate a senior frontend developer from a mid-level one.
Technical & Live-Coding Interviews
Instead of memorising answers, Juliana built a repeatable process for technical interviews, live-coding challenges, and take-home tasks — shipping production-ready solutions under pressure.
Fundamentals: Testing, Performance & Software Architecture
Juliana went deep on the senior fundamentals — testing, performance, and software architecture — and the mental models that outlast any framework or library.
CS Foundations: Data Structures & Algorithms
Juliana closed the data structures and algorithms gaps that self-taught and bootcamp paths leave behind, and started solving problems by reasoning rather than recall.
Selling Yourself & Communicating Senior-Level Value
Juliana learned to communicate real engineering value — a senior-level CV, LinkedIn, and STAR interview stories — so the level showed long before the offer landed.
