Developed an automated EDA license provisioning and reporting platform to manage a $100M+ FlexLM license pool supporting the Microelectronics Commons; generated cost-optimization insights that drove $20M+ in savings.
Built pylmstat, a custom Python CLI tool that integrated with Azure Entra ID and FlexLM. This provided users a secure, self-service method to view project-specific license availability, improving user experience and eliminating an entire category of support inquiries.
Implemented centralized application logging in AWS CloudWatch, creating actionable alarms that trigger AWS Lambda functions to resolve common issues without manual intervention.
Acted as the primary escalation point for hundreds of EDA engineers, providing expert troubleshooting for complex toolchain, infrastructure, and licensing issues.
Developed CI/CD pipelines in GitLab using Packer and Ansible to build and provision custom RHEL AMIs, reducing the time to deploy fully configured EDA environments from days to minutes.

Automated project job costing by extracting line items and PO from invoices using Python and GPT-4 vision API.
Developed a RAG system to enable searching all project communications and documents from a single interface using Python, LlamaIndex, and Google Workspace/GMail APIs.
Extracted key details from PDF blueprints like foundation type, number of rooms, finishes, building codes/ULs, etc using MuPDF and GPT-4 to cut time to estimate by 50%.
Oversaw the planning, construction, and completion of three custom homes on time and within budget.

Designed, built, and installed prototype camera and computer vision system for detecting misaligned blanks in automotive stamping presses using GStreamer, Python, and GigE cameras.
Created a Django application for viewing live streams of stamping presses as well as video clips of the 60 seconds before any downtime events.
Designed, built, and implemented an automated machine runtime tracking system that interfaced with dozens of Siemens and Allen Bradley PLCs using the snap7 and pycomm3 libraries.

gstreasy - Python library for interfacing with the GStreamer multimedia framework. Github
civ4save - CLI tool and library for decrypting and parsing Civilization IV save files. Github

Python - Expert Level
Bash/Unix tools - Advanced
SQL - Advanced enough to design high quality schemas and indexes and read query plans
Go - Intermediate level
HTML/CSS - Better than you'd expect from looking at my website
JS - Yes but only in anger
Zig - I've dabbled and like it
C/C++ - I've mostly done reverse engineering work. For new stuff I'd probably just use Zig.
PowerShell - For those random M365 cmdlets still don't have a corresponding Graph API endpoint

Linux - Ten years of daily driving on desktops, laptops and servers. Red Hat is my favorite flavor but Debian is great too.
SQLite - Constantly finding new uses for it. I know enough to know you have to turn on foreign keys and strict typing
Postgres - Have operated and maintained production databases for years
Django - Written multiple production apps in Django and I love the ORM
Docker - alias docker=podman
Ansible - Competent but I do prefer pyinfra
GStreamer - Very comfortable developing complex media pipelines
Terraform - My work experience has only involved fighting to update ancient terraform deploys
Kubernetes - Only ever used k3s and podman kube
PyTorch - I mostly worked on pre LLM computer vision models
Azure - Only if I have to
AWS - At least it's not Azure. Heavy user of IAM, S3, Ec2, Lambda, Cloudwatch, Control Tower, Cloudformation, LZA
Entra ID - I wrote a CLI for managing complex group heirarchies that used the MS Graph API
SharePoint - I wrote a Markdown to SharePoint page transpiler so I didn't have to actually use SharePoint
FlexLM - I know entirely too much
OPC UA - I've written industrial process simulators that expose an OPC UA server

Open WebUI - I run this on exe.dev.
Manyfold - Hosted on my home server and shared with friends for serving storing and serving STLs
radicale - For a shared calendar with my wife.
ros2-dev - An ubuntu22.04 virtual machine with passed through Intel ARC GPU for doing robotics development and simulation work. It runs sunshine friends and I remote in using moonlight.
win10-opcua - A windows 10 virtual machine running Kepware and Ignition for developing and testing OPC UA applications.
