THE STORY

- 03
Then the lead layer: owning technical decisions, carrying design discussions.

THE SENIOR JOURNEY
The senior skills Valeria built
Getting to senior isn’t about learning another framework. Valeria’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
Valeria learned to lead system design and frontend system design discussions — scalability, data flow, and architecture trade-offs — the conversations that separate a senior lead frontend engineer from a mid-level one.
Technical & Live-Coding Interviews
Instead of memorising answers, Valeria 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
Valeria 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
Valeria 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
Valeria learned to communicate real engineering value — a senior-level CV, LinkedIn, and STAR interview stories — so the level showed long before the offer landed.
