Elias B. — Software that makes complex things easier to understand

Elias · Software engineer · London

I work across systems, data, and interfaces. I like understanding how a product works underneath as well as how it feels to use.

HereMy projects, a few experiments, and some things I enjoy.

Fantasy football models

I’m exploring matchup views, rankings, and draft tools for my Sleeper redraft league, with a small prediction model as a possible next step.Read experiment note

The homepage shows the live matchup when Sleeper is connected. I keep the other managers anonymous, and I’m still experimenting with rankings and predictions.

Interface studies

Small interface studies about states, controls, motion, and the details that make a product easier to use.Read experiment note

I’ll add a study when there’s a decision or lesson worth sharing, including ideas that didn’t work.

04 / About

A bit about me.

I’m based in London, where I work on high-performance pricing and risk systems. Outside work, I build my own products end to end: I find the problem, shape the experience, write the code, and work through the awkward parts until they make sense.

I like software that respects the person using it: clear about what’s happening, dependable when things go wrong, and careful with the details.

Career path

My career so far.

I started in marketing and data, moved into AI model training, and now work in software engineering.

01
Earlier
Data and marketing
I started in marketing, working with data and experiments. I became curious about why some experiences worked better than others.
02
Then
AI model training
Training and evaluating code for language models taught me to check whether an answer actually holds up. A plausible response was not enough if its reasoning or code was wrong.
03
Now
Software engineering
Today I build high-performance pricing and risk software in C#, alongside personal products in TypeScript and Python.
