I build tools that remove manual work from your workday.

I've spent the last decade buried in business data: spreadsheets, CRMs, reports. Now I build tools that automate it.

Latest build

From two days a monthto five minutes.

zérosaisie reads any SAQ invoice, applies the right accounting treatment, cross-checks the figures, and outputs data ready to paste straight into the books. Built for a Quebec wine agency.

Services

What I Do.

Strategy, execution, and custom software, depending on what the problem actually calls for.

Custom Web Apps & AI Tools.

Real tools, built for specific problems.

Over the past few years I've learned to build and ship production-ready web apps and AI tools — the kind smaller businesses need when off-the-shelf software almost fits but never quite does. AI agent platforms, invoice-automation tools, workflow automations, apps built around one specific problem from the ground up. The starting point is always the problem, never the technology.

Techstack I reach for: React, Next.js, Python, Supabase, n8n and the Claude API, deployed on Vercel.

AI Consulting & Training+

Digital Setup+

Digital Setup.

Getting a business properly online, done right from the start.

A solid strategy doesn't mean much if the basics aren't in place. I handle the groundwork — building websites, setting up social media channels, getting Google Business profiles live and properly optimised so both people and search engines can find them.

Fast, clean and built to hold up over time.

Website creation, social media setup, Google Business profile optimisation.

Marketing Advisory+

Marketing Advisory.

An honest outside perspective, whenever it's needed.

Sometimes the most useful thing isn't a big project, it's a straight conversation with someone who knows enough to give real advice. I work with founders, small teams and individuals who want clarity on their marketing, want to learn something specific, or just need a trusted person to think things through with.

I don't believe in hoarding knowledge. If I know something useful, I'll share it.

One-off sessions or ongoing, whatever makes sense.

Real tools, built for specific problems.

Techstack I reach for: React, Next.js, Python, Supabase, n8n and the Claude API, deployed on Vercel.
