My story
Why I built Stakkr
The maths that made me leave a job I’d spent five years working towards — and the calculations that replaced it.
A bit about me. I have a physics degree and a master’s in space systems engineering. After university, I landed a job as an engineer at a space company — the kind of job 10‑year‑old me would have been thrilled to have. On paper, I was on the exact trajectory I’d spent five years building towards.
What changed things was working out my real hourly wage — what I actually took home once tax, National Insurance, student loan repayments and commuting were all accounted for. The job stopped looking like security and started looking like a trade I’d agreed to without reading the small print: my best hours, every day, for a number that shrank every time I looked at it properly. 3 years into the role, I walked away from it — not into another job, but with a handful of flexible income streams I prepared before my departure.
The idea the whole site is built on
The Stackable Income Method
None of them were going to replace an engineer’s salary on its own. But stacked together, on my own schedule, they didn’t need a manager’s permission to grow. That’s the idea this whole site is built on: the Stackable Income Method — several flexible income streams layered on top of each other until, together, they can replace what a salary was paying you. The tools I’ve built on this site follow the exact calculations I used to replace my income.
