Solo developer · Financial software

I build trading tools, and I prove whether they work.

Backend, frontend and deployment, on my own. Five projects below — one of them is here because I shut it down after the data said it had no edge.

TradeWiseDecide before you click buy

A mobile-first tool that helps a beginner judge one trade. It reads fundamentals, technicals and news sentiment, then makes you commit to a stop, a target and a position size before it shows its verdict — the discipline is the product, not the signal.

Paper trades only; it never touches a broker. Every trade is journalled and replayable against historical bars. I built the legal layer too — disclaimer, privacy policy, and a consent record where the database stamps the timestamp, because a browser-supplied one proves nothing.

Killed on the evidence May – Jun 2026

CL_BOTA trading bot, and the case against it

I built an automated crypto trading system, ran it live on paper, and then proved to myself it did not work. Two opposite paradigms — trend-following and mean-reversion — both failed across 365-day backtest sweeps.

Before closing it I tested the strongest remaining lever: a 120-cell strategy × regime × stop-loss matrix with an n ≥ 30 guard, so small-sample flukes could not pass as edge. Every qualifying cell was negative. I wrote the postmortem and stopped.

Niche DiscoveryAn evidence engine for product ideas

A pipeline that finds underserved e-commerce niches from real public signal rather than guesswork: Reddit, Stack Exchange, Wikipedia, US Bureau of Labor Statistics and YouTube, normalised into comparable entities, then scored and ranked with an explicit confidence measure.

Cost was a design constraint. The expensive AI path is opt-in, each run is metered and pre-flighted against a budget, and free mode is the default — an engine that quietly spends money on speculative research is a bad engine.

DZIRIAlgerian Darija, for my toddler

An offline-first app teaching spoken Algerian Darija to a small child — audio-first, one word at a time, no reading required. Built for my own kid, which makes it the only project here with a user who gives completely unfiltered feedback.

Every word is checked with a native speaker before it ships. The dialect is specific enough that guessing produces something confidently wrong, so the app does not guess.

StockIQThe version before TradeWise

My first attempt at stock-analysis tooling: a Python server with a browser front end doing screening and trade planning.

Work stopped on 17 May 2026. TradeWise's first commit is dated 18 May. I kept what was right and rebuilt the rest rather than patching an architecture I had outgrown. It is listed because replacing it was the correct call.
