Manuele Sapia
// Frontend Engineer · Brittany, France 🇫🇷
THE STORY
Manuele’s Path To Senior
- 01
Manuele knew pieces of everything and owned none of it. Sound familiar?
- 02
The structure let him rebuild from scratch: the JavaScript engine, rendering, architecture. Fundamentals first, frameworks second.
- 03
Then the part engineers skip: selling it. A senior-grade resume. Interview stories that carry the technical weight.
- 04
Senior level in Brittany. Salary up.

IN MANUELE’S WORDS
“The training is really structured in a certain way that I could learn from scratch, especially the fundamentals and how to sell myself with the interview.”
THE SENIOR JOURNEY
The senior skills Manuele built
Getting to senior isn’t about learning another framework. Manuele’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
Manuele 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, Manuele 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
Manuele 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
Manuele 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
Manuele learned to communicate real engineering value — a senior-level CV, LinkedIn, and STAR interview stories — so the level showed long before the offer landed.
