Custom software and automation for tipsters and betting channels

Bots that watch the odds for you, automatic alerts on your Telegram channel, historical data and apps for your subscribers. You focus on the channel, the software does the repetitive work.

Problems I solve

If one of these sounds like you, I can help.

  • The problem: “I spend hours staring at odds so I don’t miss a move.”

    What I do: A bot checks the odds every 2 minutes and messages you on Telegram only when something changes.

  • The problem: “By the time I notice a market is open, the good price is gone.”

    What I do: An alert tells you the very moment a new price is published.

  • The problem: “I’d like to try a strategy, but I have no real data to test it on.”

    What I do: An archive with hundreds of thousands of matches and odds that updates itself every day.

  • The problem: “My subscribers have no clear way to see my results.”

    What I do: An app that records betting slips and works out returns, wins and stats on its own.

  • The problem: “I post everything by hand and the channel stops when I’m away.”

    What I do: I automate posts, deals and affiliate links: the channel keeps working while you sleep.

What I’ve built

Four real projects. Clients stay anonymous and the data in the examples is made up.

Odds monitor with Telegram alerts

TennisTelegram24/7
The problem
A group of tipsters spent hours watching odds to catch new markets and price changes on tennis singles, doubles and special markets.
What I built
Bots that check the odds of the main Italian bookmakers about every 2 minutes. When a match opens or a price moves, they post a clear message to the client’s channel right away.
The result
Nobody has to watch the odds all day any more: subscribers get the alert automatically, day and night.

Alerts when new markets open

FootballOutrights
The problem
On football stats markets (shots, fouls and the like) and on outrights, the best prices don’t last: by the time you notice, they’ve already moved.
What I built
A system that spots the moment a price is published for the first time and sends a single alert, already sorted by category. No duplicates, no noise.
The result
The client gets to new prices first instead of chasing them.

  1. 10:02:14

    The bookmaker publishes the price: Total shots Over 24.5 at 1.95

  2. 10:02:31

    The alert lands on your channel, just once

    you were already there

  3. 10:41:00

    The price has already dropped to 1.72

Historical data archive

FootballTennisData
The problem
Without real data you can’t check a strategy or prove your track record.
What I built
An automatic collector that saves matches, odds and closing odds every day, and fills in missing days by itself. It is protected against anti-bot blocks, so it doesn’t stop.
The result
Over 533,000 football matches and 9,100 tennis matches ready to analyse, always up to date.

Curvalo, the app that keeps score of your slips

Mobile appAIEnglish and Italian
The problem
People who follow a tipster want proven results, not scattered screenshots.
What I built
A mobile app: you take a photo of a paper betting slip and AI reads the matches, odds and stake. Then the app checks the outcome by itself and updates returns, win rate, streaks and per-sport stats.
The result
A clear track record that’s easy to share, with slip images ready for social media, push notifications and a Pro subscription.

  • A bot posts Amazon deals to a channel every 10 minutes, around the clock.
  • An automatic backup runs every night and is kept for 14 days.
  • An automatic check restarts any bot that gets stuck.
  • After a failure I rebuilt a whole server from scratch and brought everything back online.

What do you need?

Pick one or more services: I’ll write the message, you just send it.

Your message

Hi Stefano! I saw your page. I’d like to talk about a project for my channel. Here’s my idea:

Send on TelegramSend by email

Telegram opens with the message already written: you can change it before sending.

How I work

Four steps, no surprises.

  1. Listen

    You tell me what you need in your own words. No tech talk.

  2. Quick demo

    Within a few days you see a first working version and know right away if it’s the right path.

  3. Build

    I finish the project, put it online and show you how to use it.

  4. Support

    I stay around: I check that everything works and improve it when needed.

Got an idea for your channel?

Write to me even just to ask whether it can be done. You’ll hear back from me, not a bot.
