LAMOSE — an e-commerce brand run by an AI workforce

live

My drinkware brand runs day-to-day without me. Sixteen AI helpers watch sales, inventory, pricing, and ads, then send me a morning briefing — and ask permission before touching anything that matters. I spend minutes a day on what used to take all of it.

AI Ads Manager — replacing a $3–5K/mo agency with $32/mo of software

live

Ad agencies wanted $3–5K a month to manage my Google Ads. I built software that does the same daily tuning for about $32 a month — and it now runs the advertising for four businesses, managing ~$9,150/month in ad spend.

Autonomous SEO agent — $11/year in AI costs

live

A tireless marketing assistant that makes two of my websites a little better every single week — fixes problems, sharpens page titles, writes three blog posts — and emails me what it did. Its AI bill: about $11 a year.

R.Song Studios — ops dashboard for a 3-location fitness studio

live

Calgary's largest pole & aerial fitness studio was running three locations on spreadsheets and exports. Now one dashboard shows the owner exactly where revenue moved, which classes keep members coming back, and runs payroll — trusted with real paycheques every month.

shca.ca — community association platform with real money flows

live

A volunteer community board needed what big organizations have — online memberships, hall bookings with deposits, and expense approvals that require three signatures — without office staff or an enterprise budget. The whole platform runs for about $20 a month.

PharmacyPlus — AI operations for a retail pharmacy

live

I own a Calgary pharmacy with about six employees. Its schedules, timesheets, payroll and sales reports prepare themselves — with strict rules that keep AI far away from patient information and anything medical. Proof this works even in a regulated industry.

yycchinesefood — ordering platform for independent Chinese restaurants

wip

Delivery apps take 20–30% of every order from Calgary's independent Chinese restaurants. I'm building them a shared way to take orders directly — starting with ten founding restaurants. In progress, documented in the log as it happens.

Calgary Mandarin School — registration, payments, and peace of mind

live

A community language school was handling registration on paper and chasing payments by hand. Now families register and pay online in one sitting, the calendar updates itself from a spreadsheet the staff already use, and it all runs on infrastructure that costs almost nothing.
