15. Building blank — an autonomous trading advisor — plus Smoke City (e-commerce for bike parts) and cr-engine (an AI-first game engine in Rust). Solo, shipping code.
Software that pays for the next piece of software. Each one ships standalone, each one cross-pollinates the next, each one is built solo with AI-assisted development tools outside school.
Autonomous trading advisor · Windows · Mac · iOS · cloud
An autonomous trading agent that reads the market the way a senior PM does — news, social, options flow, charts — and executes trades with adaptive cadence. Practice mode runs a £100 sandbox per user; live mode executes real money trades on Trading 212. The advisor learns from every closed trade. Each user's instance trades independently. 100k+ lines of code. Built solo. Currently in beta.
useblank.aiE-commerce for motorcycle & scooter parts
A full e-commerce platform built for a real family-run bike shop. Customer storefront with category browsing, search, and Stripe checkout; admin panel with barcode-assisted inventory, order processing, invoice emailing, and Royal Mail shipping workflows. AI-powered bike finder for part compatibility. Built end-to-end — backend, frontend, ops tooling — so the shop actually runs on it.
smokecitysupplies.comAI-first game engine · Rust · wgpu
A game engine designed for the era where AI agents direct the scene. Workspace of nine Rust crates — renderer, terrain, scene graph, ECS, glTF importer, physics, asset pipeline — plus an MCP-over-stdio bridge so an LLM can drive the engine through a tool surface instead of a keyboard. Native wgpu graphics. Built solo.

A giveaway generator made for creators, with creators. Backend archived; design available as a reference.
pickusawinner.comWeb development studio · parent company
The umbrella every product launches under. One founder, one brand, one design language. The studio site is an audit trail — visitors see what ships, what's mid-build, what's in the pipeline. Structured as a holding company so investors can see the company trajectory, not just the latest code push.
certifiedrandom.onrender.comSelf-taught Python over four months to complete the Duke of Edinburgh Bronze Award's skills section. A free online course, a Windows machine, and an idea that I could automate boring stock research. Wrote my first scraper. Realised the bottleneck wasn't the language — it was that I didn't know what to ask it to do. This is where it all started.
Tools that turn "I don't know how" into a 20-minute conversation. The productivity gap between a teenager who uses these tools fluently and someone who doesn't is bigger than most professional gaps in any industry. I stopped worrying about writing every line by hand and started shipping specifications instead.
Started writing specifications and reviewing diffs instead of typing every line. blank's 100k+ lines aren't written faster — they're directed. Parallelised the work so a solo founder can supervise multiple AI agents working in concert. Solo means solo strategy, not solo typing.
blank goes public in July. Smoke City Supplies already serves a real bike shop. cr-engine is being built in Rust for the AI-directed games to come. Certified Random is the holding company that will outlive any one product. Looking for the right round — early, small, lean — to compress what would take three more years into one.

note · blank is 100k+ lines of code built in Python. Stack spans Python, Rust, TypeScript, React, Express, PySide6, Swift.
A determined teenager with AI-assisted development tools now ships at the output of a small product team in 2020. The bottleneck is no longer how fast you can type or how many engineers you can hire — it's whether you can hold a clear specification in your head and review what the machines produce. That skill is age-blind.
blank is the bet that this is also true for trading. An independent trader with blank as their advisor, reading the same news the buy-side reads with adaptive cadence, can compete on signal — not on speed, not on capital — for the first time. blank exists to give them the workbench.
Pick Us A Winner is the cash-flow business that funds it. Certified Random is the holding company so the right deal structure works at the parent level, not the product level.
