I’m Kyle Kulhanek. I build custom software, automations, infrastructure, and physical prototypes. My work often combines several of those areas in one project.
01 — Scope
I work on projects that cross those boundaries: software that operates equipment, automations that connect existing systems, and prototypes that require both mechanical and technical development.
Selected work
Each project below includes a public GitHub repository with source code, documentation, implementation details, and known limitations.
A privacy-first browser tool that imports shipping-label PDFs and images, detects content, crops and rotates intelligently, calibrates for real printers, and generates dimensionally accurate commercial label sheets—without uploading a customer’s documents.
A standards-based path from a physical Zigbee button and Brother ADF scanner into Paperless-ngx, with locking, bounded retries, atomic file delivery, and hardened services.
Source & architectureGitHub ↗A completed commercial experiment turned open-source reference: reproducible public-data ingestion, immutable snapshots, validation, search, reports, and an optional storefront.
Read the honest post-project recordGitHub ↗A tiny, targeted Linux service that fixes clipped dialogue caused by downstream HDMI equipment mistaking digital silence for inactivity.
See diagnosis and implementationGitHub ↗Mechanical and electrical modifications for a large-format printer: custom cable-chain interfaces, probe geometry, component relocation, cooling, firmware, and editable Fusion 360 source.
Inspect models and firmwareGitHub ↗02 — Capabilities
My projects often involve connecting software to devices, making automations reliable, deploying self-hosted services, or turning a physical concept into a working prototype.
Turn repetitive, failure-prone handoffs into observable workflows across devices, APIs, files, and people.
Python · Shell · REST/WebSocket · Home AssistantDesign, deploy, isolate, and document services with practical networking, virtualization, storage, and recovery in mind.
Linux · Proxmox · containers · DNS · VLANsBuild focused web tools and data systems around a real workflow instead of forcing the workflow around generic software.
TypeScript · React · Python · SQL · PDFMove between scan, CAD, print, electronics, firmware, and fit testing to produce functional physical solutions.
3D scanning · CAD · FDM · embedded systemsReproduce ambiguous failures, isolate the real boundary condition, and leave behind a repair that can be verified.
Linux · Windows · networks · hardware/software boundariesHow I work
I start by reproducing the problem, test the highest-risk assumptions early, build the complete workflow, and document how to operate and recover it.
Observe the environment, reproduce the failure, and separate the requested fix from the underlying need.
Test the riskiest assumption early with the smallest credible implementation.
Handle interfaces, failure states, usability, security, and rollback in addition to the core function.
Use repeatable checks and write down operation, limits, and recovery while the details are still known.
Source code and documentation
My GitHub profile contains source code, setup instructions, design decisions, security notes, and known limitations for the projects shown here and several smaller Home Assistant tools.
