§Systems Integration & Digital Transformation Agency

Cut the between your tools. Keep the tools.

We build the integration layer that turns the tools you already own into the system your team runs on, from websites to full internal platforms.

What we build

Six capabilities, one system. Most engagements combine several.

Web Development

Websites built as business systems: lead capture, analytics, and integrations wired in from day one.

E-commerce Systems

Online stores built to scale past off-the-shelf platforms.

Business Automation

Custom workflows that remove the manual steps between the tools you already use.

AI & Intelligent Systems

AI that lives inside your business systems, not outside them.

Data & Analytics

One dashboard. One source of truth. No more spreadsheet exports the night before a board meeting.

System Integrations

Unify business tools into a single connected ecosystem.

What the work actually looks like

Most integration builds live in code like this — a FastAPI router normalizing a webhook from one system and pushing state into two others. Twelve lines here, an evening’s worth of thinking behind them.

Need leadership, not a build?

We also take on Fractional CTO engagements — standing technical advisor on architecture, tooling, hiring, and roadmap. Monthly retainer, 10–20 hours, month-to-month. Senior operator experience, not a junior consultant bench.

How we deliver

Every engagement starts with a paid $2,500 Diagnostic — two weeks of scoping work that ends in a written roadmap you keep. Build work follows only if the roadmap makes sense to both sides. Fixed-price milestones, no hourly billing, no open-ended retainers.

Every surface we ship is wired into the rest of your operation.

Start with a Diagnostic. Two weeks. A real roadmap. Yours to keep. We take on 2 new builds per quarter.
