Jason Fetzer

I build algorithmic systems, operations research tools, data platforms, and grounded AI software for real-world operations.

My work is centered on problems where feasibility matters, interfaces need to earn trust, and software has to help people make better decisions under real constraints.

Start Here

  • Talk to My Machine
    A manufacturing digital twin and operations assistant for corrugator scheduling, runtime visibility, analytics, and operator-readable decision support.

  • Operations Research Algorithms
    The portfolio hub for my public solver work across scheduling, cutting stock, packing, transportation, transshipment, and greedy methods.

  • Felix/August
    A long-horizon investment journal for my sons, focused on AI, hardware, infrastructure, energy, and generational wealth.

Public Solver Repos

Current Themes

  • combinatorial optimization
  • scheduling and sequencing
  • cutting stock and packing
  • transportation and transshipment
  • industrial AI and decision support
  • data engineering and warehouse-backed analytics
  • manufacturing systems and plant-level runtime visibility
  • workflow and platform tooling

In Progress

  • Talk to My Machine application
    The full operating product is still private while I continue building and hardening it locally.

  • Fabric administrative tooling
    A real Microsoft Fabric workflow and admin tool that I plan to publish in sanitized, better-tested form.

  • Capacity planning work
    Earlier plant-capacity modeling work that can likely be repackaged into a stronger public operations research showcase.

Learning and Systems Work

I keep older school, systems, and exploratory repos visible because they show how I learned: algorithms, databases, software engineering, assembly, geospatial work, and architecture projects all feed the way I build now.
