Most engineers own one layer. I own the chain — from solder joint to Stripe subscription.

I'm Sam Warth. I design circuits, write firmware, provision infrastructure, and ship frontends — then stand behind the whole chain. Most engineers specialize in one layer. I architect across all of them, from the copper traces on a PCB to the Stripe webhook that bills a customer.

As founder-CTO of PaktPerfect, I've taken a product from zero to 500+ active users — handling everything from real-time collaborative canvas rendering to multi-tenant billing architecture. As a hardware engineer on the Cartainers project, I've gone from KiCad schematic to field-deployed ESP32 sensors with live cloud dashboards.

Currently shipping PaktPerfect features based on customer feedback while building AutoTopo — a desktop app that turns topographic data into 3D-printable relief models using Rust, Python, and React.

Shipping features based on direct customer feedback.

  • A
    AutoTopo
    Independent Developer
    2024Present

    Building a desktop application that transforms geospatial data into physical 3D-printed terrain models. Engineered the full pipeline: raster elevation data → vector geometry processing → print-optimized layer slicing. Rust backend handles heavy computation; React frontend provides interactive exploration. Ships native via Tauri.
