Lachlan Coleman-Barrett
AI Systems Architect & Growth Engineer
Digital marketer and software developer with experience across SEO, paid advertising, marketing automation, CRM systems, and AI agent development. I build complete business infrastructure — connecting marketing, sales, CRM, and automation into unified growth systems with AI at the core.
Background in web development, SaaS tooling, and cloud infrastructure. Previously worked across e-commerce (Amazon FBA), digital marketing agencies, and SaaS automation. Currently based in Asia, building AI-powered growth systems for businesses.
The infrastructure below serves as my Personal Management System (PMS) — a live operating environment I built to manage my own business, automate workflows, and develop AI agents. The same architecture powers client-facing systems.
All systems are live and running in production. Live demos available on request.

Frequently Asked Questions
Common questions about working together, timelines, and what to expect.
Primarily local service businesses — handymen, plumbers, trades, clinics, and similar. I also work with SaaS founders and agencies who need AI-powered automation systems. If your business relies on leads, bookings, or repeat customers, we are a good fit.
Agencies sell you ad spend and reporting dashboards. I build systems that run without you — automated follow-ups, AI-powered lead reactivation, missed-call recovery, and review generation. The difference is you keep the systems after we work together. They compound, agencies do not.
We start with a 30-minute discovery call to understand your current setup and goals. From there I build a custom proposal with exactly what I would implement. Once approved, most systems are live within 2–3 weeks. You get a dedicated channel for communication throughout.
Zero. Everything is built, deployed, and managed for you. You get a simple dashboard to see what is happening, but the entire point is that these systems work in the background while you focus on your business. If you can check your phone, you can use what I build.
It depends on scope. A basic automation package starts around $2,000/month. Full-stack builds with custom dashboards, AI agents, and multi-channel automation are quoted per project. I do not do hourly — you pay for outcomes, not time.
GoHighLevel for CRM and automation, Next.js and Vercel for web apps, Supabase for databases, N8N for workflow automation, Claude AI for intelligent agents, and Cloudflare for security. Everything is production-grade infrastructure, not duct-taped plugins.
Absolutely. I can walk you through live demos of any system listed on this page — the dashboards, automation flows, AI agents, everything. Most clients are surprised that these are not mockups. Book a call and I will show you the real infrastructure running right now.
I run 24/7 uptime monitoring on all client systems with automated alerts. If something goes down, I usually know before you do. Active clients get same-day fixes. I also have disaster recovery documentation for every system I build — nothing is a black box.
Both. Some clients need a one-time system build — I hand it over with documentation and you run it. Most prefer ongoing management where I maintain, optimize, and expand the systems monthly. The best results come from iteration, not one-off installs.
Send me an email at lachlan@clearscale.co with a brief description of your business and what you are looking for. I will reply within 24 hours to set up a discovery call. No pitch deck, no sales pressure — just a conversation about whether this makes sense for you.
