Twenty-five years building the systems that power the internet.

Big ideas need machinery underneath them. I have spent a quarter of a century building that machinery — the platforms, data engines and automation running quietly under other people’s businesses. If you arrived here from a proposal, this is the long version: I wrote it, and I am the one who does the work.

Fig. 01 — Consulting, build, products. One operator across all three.
01 · Three ways in

Advice, a build, or something already built.

Same operator, same systems. The difference is whether you need a decision, a platform made for you, or one you can run today.

01 · Consulting

Advice from someone who has to live with it.

Vendor review, build-or-buy, systems architecture. A scoped engagement that ends in a written decision you can act on, from someone who builds and runs the same class of system.

FormatScoped to a decision
OutputWritten verdict
Who answersMe, personally

02 · PushButton Build

Your idea, built into a platform you own.

I design, build and launch the platform. Fixed-price quote before any money moves, progress visible in a client portal, and the source handed over at the end.

ProgressClient portal and build log
OwnershipSource is yours

03 · Products

Systems already built, ready to run.

Platforms you can take hosted or licensed, self-serve digital products, and CRM4Sale, a mature business-ops CRM sold with its source. No scoping call in the way.

SetupSame day to guided

02 · From a proposal?

What stays the same, whichever door you take.

Most bids come from an agency with a sales layer in front of the people who build. Here there is no layer. The person who read your brief writes the scope, does the work, and answers when something breaks.

04 · Range

Twenty-five years of shipping, across the whole stack.

The systems below are running today under real businesses. Most of them I sell with the source, so what you buy is actually yours.

CRM & business ops

Multi-tenant CRMs with pipelines, billing and client portals. Two lineages: PHP on MySQL, and Next.js on Postgres.

Data & enrichment

Business discovery, enrichment waterfalls, dedupe and governance backends feeding a family of products.

Outreach & telephony

Cold email at scale with deliverability built in, plus calling engines on Twilio.

AI content & social

Article, image and social pipelines on Claude and OpenAI, publishing on a schedule to real pages.

Vertical SaaS

Industry-specific platforms for trades, automotive and consumer legal, each with its own intake and reporting.

Storefronts & payments

Stripe checkout, Connect onboarding, subscriptions and payment links, wired to real fulfilment.

Provisioning & infrastructure

Vercel, Neon Postgres, Cloudflare DNS. Per-client deploys and white-label forks from one source tree.

Marketing sites

Landing pages and sites like this one, built on a single design system so they ship in days.
