Denver-based full-stack technologist and lifelong maker who has spent decades building software, exploring data, tinkering with hardware, and helping developers succeed. My work spans UX/UI, web standards, application development, data analytics, AI/ML, and practical problem-solving — and I still love learning something new every day.
Documentation, samples, developer tooling, education, and DX strategy.
Modern UI/UX, Web Components, and standards-based client architecture.
APIs, backend services, automation tools, and production-ready systems.
Database design, real-time telemetry, data pipelines, and insight generation.
Model training, computer vision, inference pipelines, and applied ML tooling.
Sensor design, device integration, and real-time data flows.
A Raspberry Pi camera and custom-trained Watson model detect whether a garage door is open or closed. Combines ML, image processing, and IoT.
Every once in a while you need to roll your own. With a splash of SVG and helping hand from Stencil, you can create a custom chart as a web component.
Upload an audio file to S3, manage the details of an AWS Transcribe job, and download the results. Include code to clean up after yourself if you are so inclined.
In this post, we put aside the charting libraries, dive into some circle math, and discover that building lightweight custom charts is easier than you think.
A real-time telemetry demo using a drone, sensors, wireless links, and satellite uplink to stream flight-style data to the cloud, illustrating a modern "black box."
A reflection on how the classic Project Triangle applies to developer relations, exploring the trade-offs when building authentic developer communities.
Handling the click event is common in web development. Tablets and phones, do not technically have click but will respond to the event at the end of a touch. Capturing touchstart can lead to improved perceived performance on these devices. Here is how to handle both.
When creating charts you will often find it useful to convert a value from the data to a pixel value. Take a value in one range, and convert it to a value in another range. This is called a linear map function. Useful for microcontroller projects as well (esp. analog sensors).
We have historically built user interfaces with point and click in mind. This was necessary as it was the only way to expose complex processes to the customer. With AI, chat is the UI - especially when enriched with supporting forms, charts, etc. No more learning a new UI.
