Lenka Kadlecová
// Fullstack Engineer · Prague, Czech Republic
THE STORY
Lenka’s Path To Senior
- 01
Lenka was working hard in Prague. The problem: no map. She didn't know what 'more senior' actually required, so every month looked like the last one.
- 02
The program gave her the map: architecture, testing, performance, data structures and algorithms. Step by step, in order.
- 03
Interviews changed. Less quizzing, more technical conversation between equals.
- 04
New role, substantial salary increase. And a clear answer to 'what level am I at?'

IN LENKA’S WORDS
“I was stuck in a place where I didn't knew what to do next, and how to get to a more Senior position.”
THE SENIOR JOURNEY
The senior skills Lenka built
Getting to senior isn’t about learning another framework. Lenka’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
Lenka learned to lead system design and frontend system design discussions — scalability, data flow, and architecture trade-offs — the conversations that separate a senior fullstack engineer from a mid-level one.
Technical & Live-Coding Interviews
Instead of memorising answers, Lenka 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
Lenka 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, Lenka 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
Lenka learned to communicate real engineering value — a senior-level CV, LinkedIn, and STAR interview stories — so the level showed long before the offer landed.
