About this gig

Off-the-shelf invoicing software charges you every month and still doesn't fit how you work. I build a simple invoicing web app around your business: your services, your line items, your branding. You own it, with no per-user fees.


What you get: a private web app where you create and send invoices, track who has paid and who owes you, and keep a record of every job. I've done this for a real client: a moving and junk removal company in Nova Scotia uses the invoicing tool I built every day to email invoices, receipts and Google review requests.


How it works: we start with a short message thread about your process: what you invoice, how you price and what goes on each invoice. I build it, you test it with real jobs, and I fix anything that doesn't feel right. You get the finished app, the source code and a short walkthrough.


Tech: React and Tailwind CSS with a Supabase database, hosted on Netlify. Works on phone and desktop. I'll show you what it costs to run, often free on starter plans or a few dollars a month.


I build with AI coding tools and review and test everything myself.

I build custom web apps, automations and hiring systems for small businesses. I work in HR as an HRIS administrator, and before that I coordinated over 200 hires across an 8-store retail district. I build invoicing, booking and guest-page tools (React, Supabase), Microsoft 365 automations with Power Automate, SharePoint and Forms, n8n workflows, and hiring kits with job descriptions and scored interview guides. My own products: Keegix for rental hosts and Staffkin for small employers. I build with AI coding tools and test everything myself.
