I will build a custom telegram bot with ai, database and API integration


About this gig
Need a Telegram bot that actually works in production, not a fragile script that breaks after a week?
I'm a Computer Science MSc graduate (TU Munich) working full-time as an AI engineer. I build bots the way real software is built: webhook architecture, proper error handling, database persistence, clean deployment.
RECENT PROJECTS
- An appointment bot linking a CRM to field agents: instant notifications, status updates via buttons, all synced to the database.
- - A voice-note bot that transcribes audio and generates AI summaries with action items.
WHAT I CAN BUILD
- Notification and alert bots (your database, shop, CRM, or any API)
- - Multi-step flows with inline keyboards
- - AI bots (ChatGPT/Claude, voice transcription, summarization)
- - Database-backed bots (users, orders, bookings, statistics)
WHAT YOU GET
- Full source code, you own everything
- - Setup documentation, no lock-in
- - Deployment support (your server, cloud, or serverless)
- - Secure webhook setup, no shortcuts
TECH STACK
Python (FastAPI) or TypeScript (Supabase Edge Functions), PostgreSQL, OpenAI/Claude/local models
German native speaker, fluent English.

FAQ
Do I need my own server?
Not necessarily. I can deploy to free or cheap serverless options (Supabase Edge Functions, Railway, or a VPS from about $5/month) and show you exactly what running costs to expect. No hidden lock-in.
Can the bot connect to my existing system?
Yes. If your shop, CRM, spreadsheet or database has an API, the bot can talk to it. Message me with the details and I will confirm feasibility before you order.
Will I own the code?
100 percent. Full source code plus setup documentation is included in every package, so you can host it, change it or hand it to another developer at any time.
Can you add AI features like ChatGPT?
Yes, that is my speciality: AI chat, voice transcription, text summarization, or connecting to your own locally hosted models when privacy or GDPR matters.
Do you offer maintenance after delivery?
Yes. For bots I have built I offer monthly maintenance retainers covering monitoring, fixes, dependency and API updates, plus a few hours of small improvements. Ask me for details.
