I will build a custom telegram bot with payments and subscriptions
Val Solomko
About this gig
Looking for a reliable, high-performance Telegram bot that won't crash when traffic spikes or double-charge your users?
I am a senior backend engineer (20+ years experience) building production-ready Telegram bots in Go (Golang) and Python. From paid membership gates to Telegram Mini Apps and CRM
integrations, I deliver clean, test-covered code.
What I deliver:
- Paid Subscription & Membership Bots: Single-use invite links, payment processing (Stripe, PayPal, Crypto, Telegram Stars), and automated kick timers on expiry.
- Idempotent Payment Webhooks: Advisory locks and signature verification so duplicate webhook retries never create double records.
- High-Speed Go & Python Engines: Minimal RAM footprint, sub-second response times, and concurrent state machines.
- Database & CRM Sync: PostgreSQL, SQLite, Redis, Google Sheets, HubSpot, or custom REST APIs.
- Turnkey Deployment: Docker, docker-compose, and systemd setup on your VPS or cloud.
Proven case: SubGate membership engine (10 concurrent identical webhooks -> 1 payment row, zero race conditions).
Message me with your flow before ordering so we can pick the right package!

FAQ
Where will the bot be hosted?
I can deploy the bot directly to your Linux VPS (via Docker or systemd) or cloud platforms like Railway, Render, or AWS. A standard $4-$5/mo VPS is more than enough for high traffic.
Will I receive the full source code?
Yes. Every package includes 100% ownership of the clean, documented source code, database migrations, Dockerfile, and setup README.
Can you integrate credit card or crypto payments?
Yes. I integrate Stripe, PayPal, Telegram Stars, CryptoBot, NOWPayments, and local gateways with full cryptographic webhook verification.
How do paid subscription bots prevent link sharing?
The bot generates unique, single-use Telegram invite links tied to each paying user ID and automatically removes expired users via scheduled sweeps.
