About

Incoming first-year student at Durham University, joint honours Computer Science & Mathematics (G411), starting autumn 2026. Spending my gap year on independent quantitative-finance and technical projects — theory through to implementation — while preparing spring-week applications in quant trading & research, sales & trading, commodities trading, and equity research.

Projects

OrderbookSim

C++ · CMake

A market-making simulator implementing Avellaneda-Stoikov mechanics with probabilistic fill modeling. Built from the ground up in C++ (CMake / MSYS2 UCRT64), with multiple trader strategies — market-making, random, and momentum — a probabilistic fill model and price model on separate RNG streams, and per-trader performance metrics. My primary quant-finance portfolio project.

AS_Research

Research

Independent research into optimal execution and market-making theory, grounded in the original Avellaneda-Stoikov (2008) framework — the theoretical companion to OrderbookSim's implementation.

Interests
Markets

Commodities (oil, metals) and geopolitics-driven macro; a developing semiconductor / energy / AI-infrastructure equity thesis.

Systems & infra

IT infrastructure automation, alternative data (satellite / SAR), and self-study in complex analysis.

Swimming

Competitive sprint breaststroke, national-level times (50m SCM ~29.04s, 100m SCM ~1:04.22).

Athletics

Track sprinter (200m / 400m), training on a strength-first sprint methodology.

Applications & prep
  • Targeting spring-week tracks in quant trading & research, sales & trading, commodities trading, and equity research
  • Applying to J.P. Morgan Software Engineering (Glasgow) and Orbis Investment Analyst
  • Working through market microstructure literature — Avellaneda-Stoikov, Almgren-Chriss, Cartea-Jaimungal
  • Drilling mental arithmetic, probability, and Markov-chain problem sets
