Welcome

I’m building a focused suite of AI tools for quantitative finance and ship operations.
Your sponsorship helps keep these projects open, local-first where possible, and continuously improving.

Projects you’ll be supporting

QuantCoder – Local-First Strategy Research CLI

QuantCoder is a CLI tool powered by local LLMs that turns quantitative research papers into executable trading strategies.
It uses an agentic workflow, an AlphaEvolve-like evolutionary algorithm, and a self-improvement loop tightly integrated with the QuantConnect LEAN engine.

Chat with Fundamentals – AI Equity Analysis Platform

Chat with Fundamentals is an AI-powered equity analysis platform built on top of EODHD API endpoints.
It lets traders and investors explore fundamentals, valuations, and key metrics through natural language, producing decision-ready equity insights.

WindMar – Weather Routing and Fuel Optimisation

WindMar is a weather visualisation and routing tool for the merchant marine.
Its goal is to help operators reduce fuel consumption and improve schedule reliability by planning routes using high-resolution wind and sea state information.

MarChat – AI Assistant for Shipboard Administration

MarChat is an AI-powered administrative assistant for ships.
It reduces the paperwork burden on officers by drafting reports, structuring logs, and handling routine documentation so crews can focus on safe operations.
