AI Agents in Python
A three-part progression from simple decision agents to LLM-powered agents and clarifying loops that ask before acting.
Technology
Software, AI workflows, architecture, and the tools I build to make the work less brittle.
This pillar collects the engineering side of the site: AI agents, Go systems, JavaScript, browser tooling, static site infrastructure, and the older experiments that still say something useful about how I work.
Recurring pattern
I usually end up here when I want more control than an abstraction is willing to give me. That could mean a custom generator, a Go library validated against a Python reference, or an AI workflow that starts with requirements before any code is written.
Technology projects
Selected systems and tools.
Go UI framework Active 2026
godom
A Go framework for local apps where the Go process owns the DOM and the browser is just a screen. No Electron, no complex JS frontend, no API layer; go build gives you one binary that opens a tab.
Trading infrastructure Active 2025
Go Backtester
A custom backtesting engine built for strategies that stopped fitting neatly inside off-the-shelf Python frameworks.
Go library Active 2026
goeph
A Go ephemeris toolkit built on NASA JPL ephemeris data, born from porting a real Skyfield-based workflow. Now the bedrock for further tooling in this space.
Game dev series Archive 2007
Quake 3 Homing Missile Mod
A beginner-friendly series on compiling Quake 3 source and modifying missile behavior to create a homing rocket.
Browser extension Published 2013
Data Explorer for Force.com
A Chrome extension for running SOQL and SOSL queries directly against Salesforce with no intermediate server.
Static site generator Archive 2013
Nirman
A flexible Node.js static site generator I built when existing tools felt too rigid and too tied to someone else's content model.
One-off tool Experiment 2025
SEO Analysis Tool
A sitemap-driven SEO analysis workflow built almost entirely with AI agents, then corrected by hand where the agents drifted.

The thin bridge: keeping bridge.js dumb on purpose

A video player that decodes frames in Go

When to write plain JS in godom (and when not to)
godom doesn't ban JavaScript; it pushes it to the edges where it actually pays for itself. Three tiers, one rule, and the trap to avoid.

A 3D solar system in Go, drawn with Canvas 2D
I wrote a 3D engine in Go and let the browser draw 2D circles. No three.js, no WebGL, no JS math libraries. Just a list of 2D draw commands per frame.
