THE STORY
Kirsten’s Path To Senior
- 01
Kirsten was consuming everything: courses, newsletters, interview threads. More input, less clarity.
- 02
The program cut the noise. One path: React internals, frontend system design, data structures and algorithms. Nothing else.
- 03
She stopped preparing for every possible question and started explaining technical decisions like a senior. Out loud. Under pressure.
- 04
Senior Frontend Engineer in New York. Salary up. And she knows exactly why her code works.

IN KIRSTEN’S WORDS
“I was able to weed out all the noise, and focus on the things that were important.”
THE SENIOR JOURNEY
The senior skills Kirsten built
Getting to senior isn’t about learning another framework. Kirsten’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
Kirsten learned to lead system design and frontend system design discussions — scalability, data flow, and architecture trade-offs — the conversations that separate a senior senior frontend engineer from a mid-level one.
Technical & Live-Coding Interviews
Instead of memorising answers, Kirsten 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
Kirsten went deep on the senior fundamentals — testing, performance, and software architecture — and the mental models that outlast any framework or library.
The Architect's Mindset
Kirsten developed an architect's mindset: making technical decisions, driving architectural discussions, and holding their own with staff engineers and CTOs.
Selling Yourself & Communicating Senior-Level Value
Kirsten learned to communicate real engineering value — a senior-level CV, LinkedIn, and STAR interview stories — so the level showed long before the offer landed.
