THE STORY
Constantin’s Path To Senior
- 01
Constantin's code was never the problem. Explaining it was.
- 02
In interviews, the engineer who can talk through their thinking beats the one who can't. Every time.
- 03
So he trained it: narrating architecture, talking through live coding, answering why, not just how.
- 04
'I got so many offers.' His words. He picked the best one, with a salary increase.

THE SENIOR JOURNEY
The senior skills Constantin built
Getting to senior isn’t about learning another framework. Constantin’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
Constantin 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, Constantin 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
Constantin 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
Constantin 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
Constantin learned to communicate real engineering value — a senior-level CV, LinkedIn, and STAR interview stories — so the level showed long before the offer landed.
