Custom web tools and AI automation for small businesses.

Modern software and practical AI — without the enterprise price tag or complexity. Built by a senior engineer who has shipped at scale.

// what I do

Custom tools, internal apps, and sites built to actually work — and built to be maintained, not just shipped and abandoned.

Chatbots, document processing, lead handling, and workflow automation that saves you real hours every week.

Bring an aging site or a manual, error-prone process up to date — without a rebuild-the-world budget.

// why Coldstart

Senior engineering experience from large-scale products — including years at Microsoft — brought down to the scale and budget of a small business.

You work directly with the person building your software. No account managers, no handoffs, no bloat.
