IN ADRIANA’S WORDS
“The offer that I got is 45% higher than my current salary, and many more benefits and the company is also much bigger.”
THE SENIOR JOURNEY
The senior skills Adriana built
Getting to senior isn’t about learning another framework. Adriana’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
Adriana learned to lead system design and frontend system design discussions — scalability, data flow, and architecture trade-offs — the conversations that separate a senior fullstack developer from a mid-level one.
Technical & Live-Coding Interviews
Instead of memorising answers, Adriana 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
Adriana went deep on the senior fundamentals — testing, performance, and software architecture — and the mental models that outlast any framework or library.
The Full Software Lifecycle: Backend & Cloud
Moving beyond the framework, Adriana grew across the full stack — backend and cloud — to deliver end-to-end and become the go-to engineer on the team.
Selling Yourself & Communicating Senior-Level Value
Adriana learned to communicate real engineering value — a senior-level CV, LinkedIn, and STAR interview stories — so the level showed long before the offer landed.
