Give your users a Telegram bot with predictable commands and useful responses. I build it in Node.js or Python, using one agreed technology and a clearly defined command list.

BASE SERVICE – 112,43 $US
Up to 3 simple agreed commands in one agreed language. Each command performs one simple action. No external API, database or payments in the base scope.

DELIVERY
Command handling, useful errors, new source code, setup instructions and agreed functional checks. Live Telegram checks require an authorized test bot, with access arranged securely. 4 calendar days and 1 revision(s) for the base scope.

OPTIONAL ADDITIONS
2 additional simple commands: +112,43 $US, +2 day(s). 2 additional commands, taking the order to 5 commands.
1 documented API, up to 2 endpoints: +168,64 $US, +3 day(s). Connect purchased commands to one authorized documented API with up to 2 endpoints. No extra commands.
1 simple database table: +168,64 $US, +3 day(s). Persist one simple agreed data model, such as a user preference. No complex permissions or data migration.
German and English responses: +€50, +1 day(s). German and English text responses for the purchased commands and a language preference.
1 additional revision: +€30, +1 day(s). One adjustment within the agreed scope.

Scope options are additive and may be selected once each. Their stated days are added to the base delivery time. Please agree on the final scope before ordering.

EXPRESS DELIVERY
For an additional €50, the base delivery time is reduced from 4 to 2 days. Delivery days for selected scope options still apply. Express delivery does not add features.

NOT INCLUDED
Hosting, production deployment, payments, mass messaging, paid API fees and ongoing operation.

BEFORE ORDERING
Send the required input, output and acceptance criteria using sanitized examples. For integrations, provide public API documentation and describe your authorized test environment. Secure access can be arranged when needed.

I am self-employed since January 2015, based in Germany and available for remote projects. Communication in English or German.

FAQ
What do I receive?
The source code created for your order, setup instructions and results of the agreed functional checks. Existing private projects and previous client code are confidential.

What does a revision cover?
An adjustment within the agreed requirements. New features, changed requirements and additional integrations need a separately agreed scope.

Are hosting and subscriptions included?
Hosting, paid API subscriptions, production deployment and ongoing maintenance are not included. Local setup instructions are included.

Can we communicate in German?
Yes. Project communication is available in German or English. Ja, wir können das Projekt vollständig auf Deutsch besprechen.

PORTFOLIO DEMO
The example is my own AI-assisted local browser simulation using fictional data. The optional Telegram adapter in that demo was not tested with a real bot token.
