Architected a voice assistant for the Pebble Index 01 smart ring: Whisper transcription, a small decision model for low-latency routing, and Llama or OpenAI for complex tool calls. Established a benchmark suite before implementation to evaluate accuracy, latency, and inference cost, guiding model selection and routing decisions throughout Claude Code-driven development. Built user-configurable MCP integrations, tunable routing between lightweight decision models and LLMs, and custom script execution on Cloudflare Workers for Platforms, abstracting away authentication and hosting.

Fundraiser page for a friend’s holiday charity run. Live sync with Google Sheets as a backend.

Fusion add-in to automatically lay out hooks across the face of an object allowing easy attachment to an IKEA SKÅDIS pegboard, fully customizable.

A platform to share full-sized file uploads, particularly photographs, without the cost or limitations of major providers. Includes auth utilizing Auth0 and Auth.js, and a suite of Cloudflare products to host the website and provide data storage.

Built an RSS aggregator to produce digests of new posts across user-provided feeds, built on Durable Objects and SQLite, with Workers for Platforms enabling user-supplied scripting for custom filtering and formatting.

Authored an open-source library simplifying Cloudflare Durable Objects: type-safe RPC to object methods, typed key/value access, payload-carrying and recurring alarms, and SQL migrations with type-safe queries. Built test-first with Vitest. Published on npm and used by File Drop and Digester.

App for users to play sudoku puzzles, including a solver which produces human-friendly techniques and hints on how to solve almost any puzzle. Future development plans include building a mobile version, implementing more techniques, a Computer Vision tool to allow users to import a picture of a board, and more.

A tool built to help analyze/visualize irregularities or patterns across a genome. Conceptualized as a tool to help a friend of mine with a piece of his Ph.D.

User friendly, WYSIWYG site builder to enable non-technical designers the ability to build websites (similar to Wix or Squarespace). Designed the UX and built a proof of concept with drag-and-drop components and in-browser editable styling similar to the Photoshop tools they were accustomed to.

Built a toolkit that cut government site delivery from 8+ hours to 2-4, removing so much of the work that the role was never backfilled after I moved into a dedicated automation position.

Replaced a manual data ingestion process consuming 400-600 content team hours for a single large client with tooling that cleaned, validated, and grouped a 500,000-row source in 30 minutes.

Data scraping tool built as an initial data source for a research project through Kansas State University. I utilized a public Taiwanese website that rendered graphical representations of historical monthly weather data from several hundred weather stations (for 15 years of data, over 140,000 individual files). The data source had no bulk download available and the data was rendered on the server-side into HTML charts. The combination of being written in a foreign language, having to parse and convert data out of raw graph nodes, and scraping 140k individual files made this an enjoyable project to solve.

This is a gigantic personal research project to study the field of authentication and authorization across the web. My goal is to learn about and build a compliant implementation for SSO (Single Sign-On). I would never use this in a truly secure context, but learning about the intricacies of the security flow provides a lot of insight into how things work.

Simple API endpoint to send myself email programmatically. Written in Node.js, hosted in AWS Lambda, and HTTP triggers in API Gateway. Email sent using Sendgrid API.

Built a comprehensive script to find, generate, and upload SSH keys to your user account in GitHub, identifying and prompting for two-factor auth if appropriate. I frequently use this when setting up new machines and new accounts. Multiple iterations. Using Bash, Python, GitHub API, and OAuth.

Designed the UX for a dashboard to manage automated screenshots of various reports. View design here.

Clone of Dropbox functionality to support Linux devices to be able to select a screen region, capture a screenshot, and copy a shareable URL to your clipboard.

Semi-fork of popular create-react-app toolkit, built in a way to provide my own personal ideal development environment for React projects. Introduces TypeScript, MobX, Prettier, a folder structure, and more. Use by running npx @jman.me/create-react-app [MyProjectName]

This project is a tool to automate the re-setup of a new Linux development machine. Implemented using Ansible and Python, this tool re-installed global dependencies in a consistent format which would not conflict for any future installs. Multiple iterations over time adding more functionality and different install types.

Project to learn about game programming algorithms such as AABB collision, rendering, and more.
