Elias · Software engineer · London

I’m a software engineer who works across systems, data, and interfaces. I care about how a product feels, how it behaves when things go wrong, and whether the person using it can understand what is happening.

Clarity is a form of care.

A recurring thread in the things I make: complex state becomes useful only when a person can see what happened and decide what to do next.

05 / About

Engineer by trade.
Curious by default.

I’m based in London and currently work on high-performance pricing and risk systems. Outside work, I build my own products end to end: finding the problem, shaping the interaction, writing the code, and returning to the awkward parts until they make sense.
