Hi, I'm Lachlan 👋

I build decision tools across quant, sport, simulation, and hardware — and I try to take each one all the way to an honest answer about whether it actually works.

A few things I've built
football-player-value Position-aware player-valuation & recruitment engine, validated out-of-sample against real league tables (+0.84 PL / +0.80 La Liga).
pokie-rng-study Passing a randomness battery ≠ unpredictable: five certified generators, four cracked from their own output.
image-intelligence Searchable visual recall with image content encrypted client-side — semantic search over embeddings the server can't read.
colmi-ring Reverse-engineering a cheap smart ring: byte-patched firmware, a measured 352 Hz accelerometer ceiling, a ring-based typing decoder.
schelling-segregation Schelling's segregation model with per-agent tolerance drawn from a distribution — making the spread of bias an independent variable, not just the mean.
rung4 A meta-learner that reads an unseen Rock-Paper-Scissors opponent from a few rounds and beats a hand-built Bayesian model at every k.
