About

Senior AI Engineer with a 1st class Master's in Mathematics and Physics, specialising in designing intelligent systems at the intersection of applied mathematics, machine learning, and full-stack product engineering. Known for shipping high-quality AI products at exceptional pace — from matching algorithms grounded in linear algebra and probability theory to LLM-powered data extraction pipelines.

Nearly a decade of experience spanning high-performance computing at JPMorgan, consumer fintech at scale, and early-stage AI product development. Equally comfortable architecting platform infrastructure from scratch, leading cross-functional delivery, or diving deep into the mathematics underpinning a scoring model. Thrives in ambiguity, delivers with precision.

Beyond the Code

🏋️

Fitness

Regular swimmer and gym-goer. Training is a non-negotiable part of the routine — it keeps me sharp and disciplined.

⛷️

Skiing

Hitting the slopes whenever I can. There's nothing quite like the focus required to carve down a mountain at speed.

✈️

Travel

Exploring new countries and cultures. Some of the best ideas come from stepping outside your usual environment.

🔨

DIY & Renovation

Currently renovating a house single-handedly. Turns out debugging plumbing isn't that different from debugging code.

🎮

Gaming

Strategy and RPG games mostly — anything that rewards systems thinking and creative problem-solving.

📚

Reading

Science, history, mathematics, and computing. Always learning — whether it's quantum information theory or the fall of Rome.

🛠️

Side Projects

Constantly tinkering with new tools, frameworks, and ideas. The best way to learn is to build.
