About

I design structured, reproducible systems that transform raw data into measurable insight.

I primarily work with Python and Java, with a strong focus on clean architecture and analytical correctness.

I work on a Linux workstation I built and maintain myself, which is where the data pipelines and databases behind my projects actually run.

Portfolio

In Progress

Data / Quant · Phases A–D complete
Event-Driven Market Probability Engine
A layered PostgreSQL warehouse and a walk-forward-validated probability model, built to test honestly whether next-day ETF moves are predictable. Measured answer: no tradeable edge, and the engineering exists to make that verdict trustworthy. 15 ETFs, 32,295 rows, 36 tests.
Data / AI · Planning
Multi-Source Financial Intelligence
A planned agentic pipeline reading official documents alongside the informal commentary around them, producing a research report and a daily feature panel. It feeds the probability engine, gets judged by a pre-registered backtest, then runs live.

Completed

Systems / C · IFT 2245
Building Operating System Components in C
Five systems written from scratch in C: a Unix shell, a multicore scheduler, a virtual memory manager with TLB and demand paging, a FAT32 reader, and a Turing machine interpreter. Graded against performance baselines with Valgrind penalties.
Algorithms / Python · IFT 2125
Implementing and Benchmarking Classic Algorithms
Stable matching, greedy against dynamic programming, and closest pair of points, each implemented then benchmarked on the same inputs. Two of the three results contradicted the intuition, including a greedy that was both slower and worse than the exact solution.
Software
MaVille — Java CLI (Maven, REST)
CLI application simulating a city management system. Includes resident and contractor profiles, notifications, data persistence, and integration with a public REST API. Built with Maven and tested with JUnit.
Software Quality
AutoParams (JUnit 5) — Presentation
Presentation and demo of AutoParams for JUnit 5. Automatic test data generation, reduced boilerplate, and exploration of key annotations (@AutoSource, @Repeat, @Freeze).
Software Quality
Unit Testing & Mutation Testing
Added targeted unit tests to the open-source GraphHopper project with JaCoCo and PIT analysis. Before/after comparison, edge cases, realistic data generation (java-faker), and measured improvements in test robustness.
DevOps / CI
GitHub Actions & Quality Gate
Built a CI pipeline with a PIT regression quality gate. Persisted baseline via cache, automated score comparison, report upload, and strict validation across all branches.
