Laravel · Livewire · React · Next.js
Workflow automation, integrations, tool-grounded AI agents, background jobs, and data pipelines: systems that quietly remove repetitive work and report to Telegram.
Node.js · Webhooks · Queues · APIs
From notification bots to full shops with payments: right inside Telegram, no app store, no install friction.
Bot API · Mini Apps · Payments · Webhooks
Backend services, APIs, auth, databases, storage: the reusable building blocks products are assembled from.
Postgres · Redis · Object Storage · Edge
Site-to-site VPN with WireGuard, CDN architecture, and caching layers: infrastructure that keeps products fast and reachable.
WireGuard · Cloudflare · Docker · Edge
A customer-support agent that shows its work: every answer grounded in tool results (order status, stock, policies), every step visible as a live trace, every run costed to the micro-dollar. Live on this site, also exposed as a public MCP server.
TypeScript · gpt-5-nano · Responses API · MCP · Zod
Recurring client workflows needed a reliable, observable runner: without the weight of a full orchestration platform.

Inbound webhooks need intake, retries, and routing before they ever touch product code.

Bot API · Mini Apps · Stars Payments · grammY
A coffee roastery (demo client “Röstwerk”) wants to sell where its customers already are: a Telegram shop: catalog in chat, Mini App storefront, Stars payments with one-tap refunds, a monthly coffee subscription, live order status, and inline sharing.
Placeholders: real projects land here as they ship.
Ask the shop's support agent a question. The right panel shows everything the model actually does: intent, tool calls, latency, token cost. Grounded answers instead of invented ones.
The model is the cheap part of a support agent. What makes one production-ready is grounding, validation at every boundary, and a fallback that never shows the visitor an error page.

Two peers, twenty lines of config each: how a WireGuard site-to-site tunnel routes a whole office subnet to a cloud VPS, the AllowedIPs semantics that make or break it, and the MTU number to fix before debugging anything else.

A Telegram shop bot is a storefront with two surfaces: keyboards in the chat and a Mini App web view, one backend behind both. What such a bot consists of, how Stars payments work, and where the app-store comparison breaks down.
