The technical co-founder you didn't have to give equity to.
Ten years building and leading engineering teams — from pre-seed startups finding product-market fit to the UK government's transformation programme. Here's the background, the track record, and how I ended up doing this.
Meet Mayur.
I spent a decade building and leading engineering teams — from pre-seed startups finding product-market fit to the UK government's transformation programme.
I'm a hands-on CTO. I write production Java, TypeScript, Python, Node and Solidity. I design cloud infrastructure, bake in security, and ship AI/ML features end-to-end. I've hired, fired, and mentored engineers, and sat in board rooms making the architecture legible to the founders and investors who have to sign for it.
Now I bring that senior engineering leadership to founders who need it — without the full-time cost or the two-month hiring loop — and to larger companies that need a specialist for a hard problem in software, data, or AI/ML. I don't just advise. I build.
London base, clients wherever they build.
I work from Paul Street in Shoreditch — minutes from Old Street roundabout — but the practice is remote-first, run over Slack, a shared repo and a standing call. London is less an address than a clock: my mornings reach Asia and the Gulf, my afternoons line up with the US East Coast and run into the West Coast morning. And I fly out for the moments that deserve a room — kickoffs, architecture workshops, board meetings, hiring loops, the first week with a new team.
A decade of shipping engineering leadership.

The questions to ask before you sign.
Twelve questions to put to an agency, a supplier or your own team before you commit money to a build — and, for each one, what a real answer sounds like next to an answer that is avoiding you. Written for the person who signs it off and can't personally check it.
You're subscribing to The Founder's Tech Brief — a fortnightly plain-English briefing for founders. The twelve questions open straight away. Unsubscribe any time. How your data is handled.
A build you can't evaluate, a demo that has to ship, or a certificate a contract is waiting on.
