I Build AI Systems That Replace Agency Work
28 years of engineering. Two e-commerce brands built and run since 2014. Now I build custom AI tools and automation that save businesses $75K+ per year — deployed and running in weeks, not months.
Based in Oakville, Ontario — serving the GTA and beyond
// What I Build
Every project follows one rule: you get a working system, not a strategy deck.
Custom AI Tools
Prompt generators, content systems, analytics dashboards — built for your specific business. Custom tools you own and control.
E-Commerce AI Systems
Product content at scale, inventory automation, multi-channel optimization. Tested on my own brands first — two e-commerce businesses running on AI I built.
Marketing Automation
Email sequences, social workflows, ad optimization. Replace repetitive manual work with systems that run while you sleep.
AI Readiness Assessment
Not sure where to start? I audit your operations, identify the highest-ROI automation opportunities, then build it.
Digital Launch & Growth
Going online for the first time? I coach product and service businesses through the full digital launch — e-commerce setup, local SEO, and LLM optimization — and build the AI layer from day one.
Product Research & Validation
Mechanical engineer turned e-commerce operator. I combine 11 years of product launches with engineering analysis and AI tools (Data Dive, Jungle Scout) to validate physical and market viability before a dollar goes to inventory.

Traditional Chocolate Shop to E-Commerce Roadmap
New owner, one week into a $537K/year business. Zero e-commerce experience. Working 84+ hours a week. Needed a complete digital transformation plan — fast.
What I built
- 18 deliverable areas — competitive analysis, pricing strategy, SEO, email, social, UGC, partnerships, financial tracking
- Custom Content Creator PRO v5.3 — web app for generating platform-specific AI prompts, handed over running
- Corporate gifting program with B2B sales materials — $80K–$300K identified opportunity
- Pricing optimization strategy — +$115K annual revenue from margin adjustments alone
- Interactive client dashboard deployed on GitHub Pages — live, browser-based, no downloads
Auto Repair Shop — Full SEO & AI-Visible Website, Overnight
A traditional automotive workshop with no web presence. Needed a professional site that would rank in local search, appear in Google AI Overviews, and answer the exact questions customers type into ChatGPT and Perplexity.
What I built
- 15-page Astro website — homepage, 8 service pages, pricing, FAQ, reviews, about, blog hub
- Full technical SEO — LocalBusiness + AutoRepair schema, FAQPage JSON-LD on every service page, XML sitemap, canonical URLs, hreflang
- LLM optimization — answer-first copy structure, structured pricing tables, 21 FAQ entries with JSON-LD so ChatGPT, Perplexity, and Google AI cite the site directly
- Full launch plan — go-live checklist, Google Business Profile setup, local citation strategy
- Built overnight by autonomous AI agent from a PRD with 18 user stories — zero manual coding
- Next: client photo shoot, blog section, and Google Business Profile activation
Two E-Commerce Brands Running on AI Tools I Built Myself
Two e-commerce brands. $2M+ in ad spend. Paying $75K-$125K annually for agencies, freelancers, and services. Needed to cut costs without cutting results.
What I built
- Custom AI content generation systems (100+ product descriptions, brand voice maintained)
- Marketing automation workflows replacing manual email, social, and ad management
- 2 iOS apps (SunUp by GearTOP, RunMate Pro) — built as a non-coder using AI tools
- Analytics dashboards aggregating data from Shopify, Amazon, Google, Meta
- Operational automation (inventory alerts, reorder triggers, journey orchestration)
// Things I've Built
Not demos. Real tools, apps, and systems deployed and running.
SunUp by GearTOP
Personalized UV safety app — burn time by skin type, 48-hour UV forecasts, family mode, AQI. Live in the App Store. Built as a non-coder.
RunMate Pro
GPS run tracking + shoe mileage management + injury prevention. Approved after 39 App Store rejections. Live since September 2025.
Content Creator PRO
Custom AI prompt generator for a $537K/year business. Replaced a content agency. Deployed on GitHub Pages and used daily.
// About Greg
Mechanical engineer. 14 years leading engineering teams at SMS-Siemag (prior PRO-ECO LTD). Then independent consulting. Then e-commerce — two brands built from scratch since 2014.
In 2024 I went all-in on AI. Built custom tools that replaced $75K+ in agency costs. Shipped two iOS apps as a non-coder. Now I build AI systems for businesses that want working solutions — not strategy decks.
// What Clients Say
Results from businesses that made the switch from agencies to AI systems.
Greg built an AI content system that replaced work we were paying $3,000/month for. The output quality is better and we don't wait days for turnaround anymore.
Client Name
Business Owner
We had no visibility into our daily numbers. Greg set up an automated reporting dashboard in a weekend. Now I see everything by 6am without anyone pulling a single spreadsheet.
Client Name
E-Commerce Operator
I expected a strategy document. I got a working system. That's the difference — Greg actually builds the thing, not just the plan.

What Most Businesses Get Wrong About AI (And What Actually Works)
The mistakes that cause AI projects to fail aren't technical. They're strategic. After building AI systems for my own e-commerce brands and working with GTA business owners, here's what I see going wrong — and what to do instead.
