Hi, I'm Sacha! 👋

I'm a Computer Science student and software engineer (BSc CS @ Maastricht University). I recently wrapped up a role as an AI Developer at Oraspire and am currently focused on building highly constrained, math-heavy systems across Machine Learning, Quantitative Finance, Operations Research, and Systems Enginerring.

🔭 What I'm currently working on

  • BSc Thesis: Developing a Python framework for streaming signal decomposition on real-time data under tight memory/latency constraints.
  • Quant Project: Building a Limit Order Book (LOB) simulator to model market microstructure, comparing execution strategies using a game-theoretic framework.

🌱 What I'm currently learning

  • Wrapping up Game Theory (Stanford) to formalize strategic decision-making in markets and systems (having recently completed Micro/Macro/Business Econ coursework).
  • Prepping for upcoming deep dives into Industrial Optimizers (MILP/Heuristics) and GCP MLOps.

🚀 Featured Past Work

  • Healthchain Access Control: Built a decentralized, consent-driven access-control stack (Solidity/Hardhat) for patient healthcare data with large-scale automated simulation tooling.
  • Transitor Routing Engine: Developed a Java-based public transport routing engine integrating GTFS datasets to compute optimal transit routes and accessibility metrics.
  • Modular AI Tutor: Engineered a real-time hint-generation system for robotics students with strict GDPR privacy compliance and performance analytics.

💻 Tech Stack

  • Languages: Python, Java, C, SQL/NoSQL, Solidity, JavaScript/TypeScript
  • ML & Data Science: PyTorch, TensorFlow, Pandas, NumPy, Scikit-learn
  • Systems & Tools: Git, Linux, Hardhat, Express, JUnit, Pytest
  • Concepts: Time-Series Analysis, Applied Optimization, Smart Contracts, Real-Time Streaming
