Telegram bots and API integrations for Google services, Stripe, Binance, WooCommerce, and Instagram, with reliable sync and operational observability.

Products delivered

Implemented notification bots, AI assistants, and workflows connected to Google Sheets/Drive/Analytics and external product APIs.

Result: integrated ecosystems with lower manual coordination overhead.

DevOps, CI/CD, and scalable architecture

Production-ready deployment pipelines with Docker, GitHub Actions, Vercel/Fly.io, Nginx, SSL, PM2, and Terraform for stable delivery and growth.

Products delivered

Designed SSR/hybrid and microservice architectures, API-oriented backends, and monorepo structures for long-term product scaling.

Result: predictable releases, higher uptime, and easier team collaboration.
