I help businesses automate repetitive work and turn manual processes into systems.

Recently, I built a complete order automation system for a food business that includes:
- A single-page website (Google Apps Script)
- Google Sheets as a CRM database
- Automatic Telegram alerts for new orders

I also develop:
- Custom backen
d systems using Flask
- API integrations between apps
- Automated reporting using Google Sheets
- Chatbots (Telegram )
- Lead capture automation using ManyChat, Make (Integromat), n8n and/or Zappier

If your business is doing things manually (orders, leads, reports), I can automate it and save you hours every week.

I’m currently looking for small projects to build my client base and can offer fast turnaround and flexible pricing.
