I build tools for
seeing difficult data.

Barcodes at difficult angles. Point clouds with millions of samples. Microscopy stacks. Marketplace data that changes every day. My projects make technical data inspectable without turning it into a black box.

Meet Tapirscan

Selected work / 2026

Four projects,
one recurring idea.

Keep the interface clear. Keep the underlying data available.

Latest projectBarcode scanning library

Tapirscan

Read barcodes you were missing.

A barcode is visible in your image, but your scanner returns nothing. Tapirscan is a Rust-powered library built to recover more of those difficult reads. It locates barcode regions, estimates their orientation, and scans along the bars at any angle. This lets it decode barcodes that horizontal or vertical scanlines can miss.

  • Reading orientation-aware sampling and higher-effort recovery for difficult images
  • Integrate JavaScript / TypeScript and Python bindings, decoded values and positions
  • Formats EAN-13 focus, with experimental opt-in readers for more formats

Scientific Image
Visualizer

Native-speed inspection for high-bit-depth, floating-point, medical, microscopy, and layered image formats. It exposes exact values and provenance instead of flattening everything to an ordinary picture.

  • Formats TIFF/OME-TIFF, DICOM, CZI, ND2, LIF, FITS, EXR, NPY & more
  • Analysis pixel values, histograms, ROIs, thresholds, particle results
  • Viewing multidimensional datasets, channels, layers, image comparison

Extension
Downloads

A daily view of the open extension ecosystem. The tracker combines Open VSX and VS Code Marketplace counts into a searchable leaderboard, with 24-hour and seven-day movement plus a history page for every extension.

  • Scope public extension listings across both major registries
  • Signals downloads, rank changes, versions, tags, trend lines
  • Access open on the web, no account required

How I work

Fast where it matters.
Inspectable everywhere.

01 Rust and WebAssembly for work that should not block the interface.

02 Measurements, raw values, and failure states stay visible to the user.

03 Browser demos make the tools easy to try; extensions keep them close to the data.
