I research and build systems. My work connects distributed data, algorithms, and formal reasoning, then tests those connections against evidence.

  1. Open-source experiment

    Faster search through cheaper questions

    Approximate string search that trades some recall for fewer edit-distance comparisons.

  2. Open-source prototype

    Reconstructing order flow from snapshots

    A C++ parser, streaming pipeline, and heatmap for examining changes in a limit order book.

  1. lob-proc: Reconstructing Order Flow from Snapshots

    A C++ snapshot parser feeding limit order book events through NATS to a browser heatmap

  2. Faster String Search: The Recall Trade-off Behind a 20x Speedup

    Measured search speedups with their recall costs, followed by the limits of the comparison with other systems

  3. Streaming vs Batch: A Case Study with Longest Consecutive Sequence

    When Union-Find beats HashSet and why access patterns determine algorithm choice
