About this gig

Spending hours on repetitive tasks? I write clean, reliable Python that does the work for you.


What I can build:

  • Scripts to process Excel, CSV, PDF and image files
  • Automations that connect your tools through their APIs (email, Stripe, Google Sheets and more)
  • Scheduled jobs that run on their own and send you reports
  • Data collection from public APIs and websites, respecting their terms
  • Custom REST APIs and backends with FastAPI
  • Small internal web apps with login and a database

How I work:

Clear, commented code with tests, so it keeps working after delivery. Secrets and passwords stay in environment files, never inside the code. You get the full source code and simple instructions to run it.


Experience:

I build and run DeMark Studio (demarkstudio.ca), a business platform written in Python with FastAPI, including online payments, email automation and scheduled jobs. I also wrote the Python tools that audited 2,417 small-business websites in a real browser, and I publish 80+ open-source tools on GitHub.

I build fast, modern websites and online stores for small businesses, with the tools that actually bring customers: local SEO, Google Ads conversion tracking and Stripe payments. I run DeMark Studio (demarkstudio.ca), where I design and host sites for businesses across Canada. I also build AI automations that save owners time: sorting inquiries and leads, drafting replies and follow-ups, while the owner always makes the final decision. Clear communication, fixed prices, and on-time delivery.
