Systems Integration & Automation

Systems integration that turns your stack into one system.

Data should move without people pushing it — with one source of truth, and one engineer accountable for the whole picture.

Everything works until something fails.

Integration moves data and automation moves work — but neither is worth much if nobody engineered what happens when a platform on the other end has a bad morning.

The failure path

Built for the bad day.

An integration is only as good as its worst day. The demo always works — the question is what happens at 2am when an API returns a 500, a record arrives malformed, or a platform changes its schema without telling anyone.

  • Retries with backoff, and a replay log for whatever didn't land
  • Alerts when a flow stops — not when someone downstream notices
  • Reconciliation you can run to prove both sides still agree

The honest no

What I won't wire up.

Not every manual step is worth automating, and not every stack needs middleware. Some of these cost more to maintain than the work they save.

  • An automation that saves ten minutes and breaks monthly
  • Middleware between two platforms that already integrate natively
  • A replatform when the real problem is one missing webhook
Data flow

Integrations

Point A to point B, reliably.

APIs, webhooks, and custom middleware that move records between your platforms in real time — with error handling, retries, and logging, so a silent failure never costs you a week of orders. Great Day Improvements runs on that pattern: WordPress VIP multisite and integration engineering for a national brand, through a merger and out the other side.

  • REST and GraphQL integrations across CRM, marketing, and ecommerce
  • Custom middleware when platforms don't natively connect
  • One source of truth — every record owned by exactly one system

Workflow

Automations

Work that happens without you.

Event-driven workflows that remove the manual steps in the middle — lead routing, order sync, reporting, follow-ups — triggered by what actually happens in the business rather than by someone remembering to do it on a Friday.

  • Event-driven workflows with error handling built in
  • AI-assisted steps where they hold up in production
  • Zapier where it's smart, custom code where it matters

Migrations

Off the platform you've outgrown.

When a platform stops fitting, the risk was never the new system — it's the move. Schema mapped first, old and new run in parallel, every record reconciled, and a rollback path that stays open until the numbers agree. Cutover happens when the data says it's safe, not when the calendar does.

  • Schema mapping before a single record moves
  • Old and new running in parallel, reconciled record by record
  • A rollback path that stays open until the numbers match

Whichever way you start.

Architect the whole system

Start from how the business actually runs: which platforms, which flows, which tool owns each record. You approve the blueprint before anything gets built.

Plug into what you have

Your stack mostly works; it has gaps. I extend it with APIs, webhooks, and middleware — no rip-and-replace to solve a two-week problem.

Start with one flow

Take the worst manual routine off the pile first. It pays for itself before the next one gets scoped.

Available on retainer or by project — same discipline either way.

How retainers work →How projects work →

From audit to handoff.

  1. Step 1

    Discovery

    Map the tools, the data flows, and the manual steps — and the constraints nothing can break.

  2. Step 2

    Architecture

    A blueprint of what connects where, what gets automated first, and why.

  3. Step 3

    Build

    Staged delivery with error handling and retries, tested on real data — not happy-path demos.

  4. Step 4

    Handoff

    Runbooks and docs so your team can run the system without waiting on me.

Live journey

A sample reorder journey, built and automated end to end.

This sample integration mirrors a reorder flow a business might use to turn a first-time buyer into a repeat customer. I built every step — from the purchase webhook and welcome email to click tracking, return visits, cart activity, and coupon redemption. Your flow will be different; I can connect and automate it across the platforms your business already uses.

  1. First orderwebhook
  2. Welcome emailResend
  3. Link clickedclick event
  4. Return visitUTM tag
  5. Add to cartcart event
  6. Second ordercoupon code

Problem: one-time customers. Solution: data-driven automation.

How pricing works.

Three ways to engage, and a fixed number agreed before any of them starts — no hourly meter, and no change order the first time a second platform turns up.

Audit

Fixed fee

The stack mapped as it actually runs: every platform, every data flow, every manual step in between — and which record each tool should own.

  • The manual steps documented, with what each one costs you
  • A prioritized list of what to connect or automate first
  • Yours to keep — whoever ends up doing the work

Project

Fixed price, milestone-based

A defined build with the scope and the number agreed before code. A single integration typically lands in 2–4 weeks; multi-system architecture or a full migration runs 8–12.

  • A blueprint you approve before anything gets built
  • Staged delivery with error handling, retries, and logging
  • Runbooks and docs at handoff

Retainer

Monthly

Standing engineering capacity for a stack that keeps moving — new platforms, new flows, and someone accountable when an API changes underneath you.

  • A predictable monthly block of work
  • Monitoring and fixes when a connection breaks
  • Cancel or pause between months

What moves the number

Bring the stack to a 30-minute call and you'll leave with a real range — not a proposal you have to chase.

  • How many platforms are in scope
  • Whether the APIs exist or middleware has to be built
  • Record volume, and how clean the data is
  • Whether anything has to migrate or run in parallel

Frequently Asked Questions

Can you plug into the systems I already have?

Yes — that's most engagements. I extend what you have through APIs, webhooks, and middleware rather than pushing a replatform. Rip-and-replace is the last resort, not the sales pitch.

How long does a systems integration project take?

A single integration typically lands in 2–4 weeks. Multi-system architecture or a full migration runs 8–12. Either way you get a blueprint with milestones before I write code, and staged delivery — never a big-bang launch.

What platforms can you integrate?

Anything with an API: Salesforce, HubSpot, Shopify, WordPress and WooCommerce, QuickBooks, marketing and email platforms, payment processors, and custom internal tools. Where no native connection exists, I build the middleware.

How do you migrate systems without losing data?

Schema mapping first, then the old and new systems run in parallel while every record is verified. Cutover happens only when the numbers reconcile — and there's a rollback path until they do.

What happens when an integration breaks?

It's designed to break safely. Failed calls retry with backoff, whatever doesn't land goes to a replay log rather than disappearing, and an alert reaches a human when a flow stops — instead of the failure surfacing a week later as missing orders. On retainer, that human is me.

Who maintains the system after launch?

Your call. Every build ships with runbooks and documentation so your team can operate it. Most clients keep me on retainer for monitoring, changes, and whatever the next platform in the stack turns out to be.

Tell me what's still manual.

30 minutes. Bring the spreadsheet, the copy-paste routine, or the platform you've outgrown — you'll leave with a straight read on how it gets connected.
