Systems we built and run in production — not slide decks.

Small businesses lose leads and admin time to calls nobody's free to answer — hiring reception staff for the call volume doesn't pencil out.

A production ElevenLabs conversational voice agent handling real inbound and outbound calls, wired into Google Calendar and Gmail for scheduling and follow-up, Notion for task memory and per-caller personalization, and native DTMF touch-tone support so it can navigate IVR menus on its own. The same architecture runs Arseniy's own admin work internally — booking, email triage, weekly self-review — before being deployed to clients.

Expats and foreign property owners in the Algarve need home repairs fast, in their own language, without hunting for a contractor — and every minute of delay after they submit a request loses trust.

Built aira-ai.net/airahome from zero to production in days: a 4-language landing page (EN/DE/FR/PT) with tiered urgency-based pricing, a lead form and WhatsApp entry point wired straight into n8n. One webhook pushes every lead to Telegram and immediately triggers an outbound ElevenLabs voice callback in the customer's own language confirming the request. A second webhook powers the on-page chat widget. No manual dispatching in the loop.

Handyman leads surface in Facebook groups and Telegram expat groups, in four languages, faster than anyone can manually watch — and scraping Facebook directly with automation risks getting the account banned.

Two independent, ban-safe intake sources feed one pipeline: a Telethon-based Telegram userbot reading expat group chats from a real logged-in account (no scraping, no automation flags), and a push-based Facebook relay through n8n. Both land on a single intake listener that keyword-filters across EN/DE/FR/RU, dedupes by content hash in SQLite, and fuzzy-matches near-duplicate leads from different sources into one card before pushing it to Telegram. A read-only stats dashboard tracks demand across two independent business verticals from the same data.

One WhatsApp number needed to do two different jobs — cold-outreach hotels for B2B sales, and handle inbound customer repair intake — each in the customer's own language, without maintaining two separate bots.

A single n8n workflow behind a Baileys WhatsApp connection dynamically builds a different system prompt per context: a structured intake persona that asks for the problem, address and urgency, quotes tiered pricing, and emits a hidden structured lead tag for downstream automation — or a B2B outreach persona per hotel and city. Same agent, same deployment, branching logic decides the job.

Changing an n8n workflow or a VPS config normally means sitting at a laptop with SSH open — not practical mid-commute or away from a desk.

A Telegram message to the ops bot gets parsed by Claude into an intended command, then routed either to a laptop tunnel if it's online, or queued directly on the VPS through a local command server — results report back over Telegram either way. A companion "Code Bridge" workflow lets a running agent session pause on a genuine decision point, write a waiting task into Notion, ping Telegram, and resume once answered — instead of hanging silently on a blocking question. A mandatory backup-before-change step is built into the workflow rules themselves.

Facebook has no public API for reading group content — and that's exactly where local repair and window-installation leads live, in closed expat groups.

Built two independent systems running in parallel. An anonymous HTTP scraper reverse-engineers the logged-out mobile site's undocumented, non-deterministic behavior — the same request sometimes returns a hydrated page with posts and author IDs, sometimes an empty JS shell, with no dependency on IP or timing — and retries with a clean session rather than giving up on the cycle. In parallel, a device-level automation loop (MacroDroid on a real Android phone) emulates a human scrolling the group list and reading text off the screen, sidestepping the API restriction entirely. Both feed the same deduplicated, classified intake pipeline used for every other lead source.
