A marketer who

learned to build.

I spent years inside a recruitment agency watching good teams lose hours to systems that were meant to save them. So I taught myself to fix it.

How I got here

Why I built Stack Logic.

I'm Jack. I spent the best part of seven years in-house at a recruitment agency, in marketing, not on a desk. My job was leads and brand, but I kept getting pulled into the engine room: why the data was a mess, where candidates dropped out of the process, why the reporting never matched reality.

The tools were all there. The CRM, the job boards, the automation features nobody had set up. The agency was paying for efficiency it wasn't running on.

So during lockdown I taught myself to close the gap, Python first, then Zapier to bridge the systems that wouldn't talk to each other, then JavaScript when the off-the-shelf connectors couldn't do the job. By the end I was building more than I was marketing, and the builds saved more time than any campaign I ran. That's Stack Logic, full time now, for recruitment agencies and search firms.

What you get

You hire me, not a team.

I'm not an agency. There's no salesperson promising the world and no junior picking up the work once you've signed. You get me, start to finish. Because I design the process and build it myself, nothing falls down the gap between the person who understood the problem and the person writing the code. That's also why I work in custom code wherever I can. It's quicker, it's more reliable, and when something needs changing later there's one person who knows exactly how it was built. One recent build, for a London search firm, took interview write-ups off each senior consultant and gave them back about an afternoon a week.

The technical side

I read API documentation for fun.

Most marketers hate the technical side. I live in it. While your consultants focus on candidates and clients, I'm in the back end: fixing the automations that quietly drop candidates or stall a placement, cleaning up the years of CRM data nobody trusts any more, and building the integration myself when the native one doesn't exist or doesn't do enough.

What I'm trained in

Certified, and self-taught.

The recruitment platforms don't really do certifications, so the Bullhorn and Salesforce work has to show itself in what I build. The platforms around the edges, I'm formally trained in: HubSpot for marketing software, data integrations, reporting and Sales Hub, and monday.com and ClickUp for onboarding, apps and workflows. The rest I learned the way I learn everything, by building it until it worked.

Book a Diagnostic Call

The call is 30 minutes. You tell me what your setup looks like and where the time is going. I'll tell you honestly what's worth automating, what isn't, and roughly what it would cost. No pitch deck, no proposal you didn't ask for.

Trusted by recruitment agencies and search firms, and a few good teams in marketing and ops.

See where your team's time is going.

It starts with a short audit of your stack. I'll show you where consultant and back-office hours are leaking, and what it would take to get them back.
