THE STORY

Jerico’s Path To Senior

  1. 01

    Jerico didn't want just any job in Birmingham. He wanted a team and a product he actually likes.

  2. 02

    That takes options. He built them: full-stack fundamentals, testing, interview practice.

  3. 03

    With several offers, he could pick for fit instead of taking the first yes.

  4. 04

    'A job where I could see myself for the next five years. I like the team. I like the product.' His words.

THE SENIOR JOURNEY

The senior skills Jerico built

Getting to senior isn’t about learning another framework. Jerico’s path covered the dimensions that actually move an engineer up a level — the same areas theSeniorDev coaches every member through:

01

System Design & Frontend System Design

Jerico learned to lead system design and frontend system design discussions — scalability, data flow, and architecture trade-offs — the conversations that separate a senior full stack developer from a mid-level one.

02

Technical & Live-Coding Interviews

Instead of memorising answers, Jerico built a repeatable process for technical interviews, live-coding challenges, and take-home tasks — shipping production-ready solutions under pressure.

03

Fundamentals: Testing, Performance & Software Architecture

Jerico went deep on the senior fundamentals — testing, performance, and software architecture — and the mental models that outlast any framework or library.

04

The Full Software Lifecycle: Backend & Cloud

Moving beyond the framework, Jerico grew across the full stack — backend and cloud — to deliver end-to-end and become the go-to engineer on the team.

05

Selling Yourself & Communicating Senior-Level Value

Jerico learned to communicate real engineering value — a senior-level CV, LinkedIn, and STAR interview stories — so the level showed long before the offer landed.
