AI Agents in Python
A three-part progression from simple decision agents to LLM-powered agents and clarifying loops that ask before acting.
Systems. Code. Markets. Time.
Software, trading infrastructure, AI experiments, and unusual research.
Built and documented here.
Four pillars
Browse the site by interest, not just chronology.
The blog still matters, but the structure now starts with the main threads underneath it: projects, technology, trading, and time.
Work
Projects
Libraries, tools, browser extensions, trading infrastructure, and experiments that turned into real systems.
From goeph and backtesting tools to older frameworks like Nirman and Livebase.
ExploreCode
Technology
AI agents, Go systems, JavaScript, architecture, debugging, and the practical side of building software.
Current writing leans heavily into AI workflows, software design, and developer tooling.
ExploreMarkets
Trading
Backtesting, strategy evaluation, trading psychology, and the systems thinking needed to survive real markets.
A mix of code-first research, practical trading process, and uncomfortable lessons.
ExploreResearch
Time
Time cycles, quantitative astrology, celestial data, and the research thread tying outcomes, astronomy, and pattern-seeking together.
Where celestial data meets quantitative methods and pattern research.
ExploreSelected work
A few projects that show how I think and build.
Trading infrastructure Active 2025
Custom 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 born from porting a real Skyfield-based workflow instead of treating astronomy code as a toy exercise.
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.
