Work Experience

Roles in algorithmic market-making, execution, and quantitative research.

QuantFi · Quantitative Developer

Schiphol-Rijk, Netherlands
  • Built and deployed algorithmic market-making strategies, incorporating volatility and skew estimation, order flow modelling, queue-aware execution, market impact, and reference price dynamics.
  • Built a dynamic liquidity allocation model for smart order routing, reducing slippage and transaction costs by an average of 5.8% through real-time optimization over aggregated fragmented order books.
  • Developed cross-exchange rebalancing methods that optimised timing and execution of inventory transfers under latency constraints, transaction costs, funding rates, and market liquidity.

QuantFi · Operational Trader

Schiphol-Rijk, Netherlands
  • Monitored production market-making algorithms, managing real-time risk parameters and system health to minimize inventory exposure during high-volatility periods.
  • Designed and deployed a live trading terminal using ccxt and native exchange APIs for real-time position and order tracking, integrating Tardis.dev for historical position reconstructions.

VU Econometrics and Data Science · Research Assistant

Amsterdam, Netherlands
  • Designed scalable likelihood-based estimation algorithms for functional scale models, optimising computational performance through vectorised computations and parallel processing.
  • Reduced execution time of large-scale Monte Carlo simulations by 92.3% on average using NumPy vectorisation and parallel computing.

Education

PhD, Master's, and Bachelor's, from applied mathematics to probability theory.

Leiden University

Doctor of Philosophy (PhD), Mathematics · Leiden, Netherlands
  • Researching decomposition theorems, generic chaining, majorizing measures, weak convergence, and Donsker–Skorokhod theorems for stochastic processes satisfying absolute regularity.
  • Organized and led a weekly graduate seminar on weak convergence and empirical process theory.

The full technical writeup, including a walkthrough of the \(\gamma_2\) functional and the majorizing measure theorem, is on the Blogposts page.

Vrije Universiteit Amsterdam

Master of Science, Econometrics and Operations Research · Amsterdam, Netherlands
  • Honours Programme, GPA 8.9/10 (magna cum laude).
  • Developed a novel functional stationarity test for multidimensional diffusion processes for a thesis project, implementing and packaging the mathematical framework into an open-source Git repository (see Projects).
  • Relevant coursework: Measure Theoretic Probability, Quantitative Financial Risk Management, Stochastic Processes, Stochastic Integration.

Amsterdam University of Applied Sciences

Bachelor of Science, Applied Mathematics · Amsterdam, Netherlands
  • Relevant coursework: Statistical Learning, Time Series, Deep Learning, Risk Theory.
§ 03

Projects

Selected work; full theory and code are on the Projects page.

Functional Volatility Surface Modelling

  • Extending the functional GARCH framework to a generalized autoregressive score (GAS) model to estimate and capture time-varying intraday volatility surfaces.
  • Designed efficient estimation procedures using B-splines, applying Numba JIT compilation to enable scalable modelling of volatility surfaces from granular intraday return data.

HRP Portfolio Allocation

  • Implemented Hierarchical Risk Parity via tree clustering using scipy.cluster to stabilize high-dimensional asset allocation, bypassing classical covariance inversion to eliminate noise sensitivity.
  • Generated a mean alpha premium of 3.9% above the benchmark across diverse simulated horizons in a look-ahead-free method that outperformed actively rebalanced benchmark portfolios.
