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

• Multi-Machine Interval Scheduling
  Java, Python, OR-Tools Python, and OR-Tools Java implementations of a multi-machine interval scheduling problem.

• Knapsack and Greedy Algorithms
  0/1 knapsack, activity selection, and related greedy / dynamic programming examples across Java, Python, and OR-Tools.

• Cutting Stock Operations Research
  Heuristic and OR-Tools-based cutting stock implementations with sample inputs, outputs, and tests.

• Transportation and Transshipment Models
  Cost-based allocation, network flow, and transshipment models across Java, Python, and OR-Tools.

• Truck Cubing and Bin Packing
  Practical packing and load-building models with heuristic and optimization variants.

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.
