Products
Four products I have taken all the way myself: idea, architecture, UX, operations, marketing and revenue. Each was built solo, and each runs in production with real, paying users.
SQLAI.ai
AI-powered SQL multitool
2022 – Sept 2026Profitable
An AI-powered SQL multitool for generating, explaining, optimising and validating SQL without losing control. It has grown from the first paying customer to over 150,000 users across 30+ database engines.
The applied AI spans RAG, embeddings, vector search and prompt design. I also own the commercial side: Stripe and Lemon Squeezy billing, subscription lifecycle, pricing, SEO and paid acquisition.

Chartmaker.io
AI charting tool
2024 – May 2026
A charting tool that accepts data in any shape, reformats it automatically and produces interactive charts from a plain-language description.
I built the normalisation layer that cleans up messy input, the chart generation on top of LLM APIs, and the rendering, customisation, image export and embedding. Hosting, deployment and billing are mine too.

WebsiteFeedback.ai
AI feedback on landing pages
2024 – May 2026
An AI reviewer for landing pages and marketing sites. It analyses a page for clarity, positioning and UX and returns structured, actionable feedback in seconds.
The product covers page ingestion and content extraction, the evaluation prompting pipeline, the structured output format and the reporting interface — plus subscriptions and billing.

ViewDiff.ai
AI-assisted diff viewer for writers
2025 – May 2026
A diff viewer for professional writers and editorial workflows. It shows original and AI-modified text side by side, so changes can be reviewed and accepted deliberately instead of trusting a black box.
I built the diffing engine, the generation flow, the review interface and the subscription tiers, and I operate the product in production.
