Telegram bot development and automation

Telegram is the #1 customer communication channel in many markets. We build bots that actually work: they collect leads, answer clients, accept payments, integrate with CRMs and analytics. From $2,000 (₽200K), MVP in 1-2 weeks.

Broadcast bots — segmented mass mailings with A/B tests, analytics
Admin bots — for internal teams: statistics, task management, CRUD ops

What's included in a standard bot

Dialog logic

Structured surveys with steps, validation, cancel and back actions. Not a linear script — a proper finite state machine.

Inline keyboards

Buttons instead of text commands. Button press handling, message editing, dynamic menus.

Media handling

Photos, documents, voice notes, video, geolocation — correct intake and storage with type validation.

Webhook or long polling

We choose based on infrastructure. Webhook for production environments, long polling for networks with regional restrictions.

Admin commands

/stats, /last, /find, /broadcast, /users — operational tools without touching the database.

Anti-spam

Rate limiting, honeypot fields, bot captcha, validation, suspicious account blocking.

CRM integration

Automated lead hand-off to Bitrix24, amoCRM, HubSpot, Salesforce, or a custom backend via REST/GraphQL.

Monitoring

Prometheus metrics, Telegram alerts on failures, health checks, clean restart via systemd.

Bot stack

Node.js 22 grammY / Telegraf aiogram (Python) better-sqlite3 PostgreSQL Redis (FSM) OpenAI / Claude / Gemini API YandexGPT Docker + systemd Telegram Bot API Mini Apps SDK Payments API
