CV

Hi there! 👋

I specialize in two directions that help businesses save time and money:


🔹 Excel & Google Sheets – automated dashboards, accounting systems, financial models, and professional reports.

🔹 Telegram Bots – tools for sales, accounting, customer support, giveaways, reminders, and internal automation.


My strong side is turning numbers and processes into clear, user-friendly solutions: dashboards, analytics, bots, and interfaces that are easy to use even for those who “fear spreadsheets” or complex software.


I help businesses to:


  • automate sales and accounting 📊

  • build financial models with forecasts 💰

  • create professional reports and analytics 📑

  • develop Telegram bots for process automation 🤖



✅ With me, you don’t just get a table or a bot – you get a ready-to-use product that really works.
