Goksen Gorgulu
// Frontend Engineer · Amsterdam, Netherlands 🇳🇱
THE STORY
Goksen’s Path To Senior
- 01
Goksen knew the Amsterdam market from the wrong side: strong companies, intimidating interview bars.
- 02
She built a foundation she could stand on: JavaScript internals, React under the hood, testing, performance.
- 03
Intimidation runs on uncertainty. She removed the uncertainty.
- 04
New job, salary up. 'I'm no longer intimidated by companies.' Her words.

IN GOKSEN’S WORDS
“I was able to build a really strong foundation and feel very confident about my knowledge and experience. I’m no longer intimidated by computer science terms and also started performing quite well during technical interviews.”
THE SENIOR JOURNEY
The senior skills Goksen built
Getting to senior isn’t about learning another framework. Goksen’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
Goksen learned to lead system design and frontend system design discussions — scalability, data flow, and architecture trade-offs — the conversations that separate a senior frontend engineer from a mid-level one.
Technical & Live-Coding Interviews
Instead of memorising answers, Goksen 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
Goksen 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
Goksen 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
Goksen learned to communicate real engineering value — a senior-level CV, LinkedIn, and STAR interview stories — so the level showed long before the offer landed.
