AI sales agents, CRM and integrations for B2B
OLX advertising for an equipment store
Goal: launch sales on OLX and see what really works.
What was built: 147 listings in 41 cities; a custom statistics panel for every listing (views, phone reveals, chats); a weekly report to the client with conclusions.
Result: 6,300+ views, 228 saves to favourites, first orders. We found the bestseller — autoclaves (5× more views per listing) — and removed «dead» listings.
We work with OLX in every country where it operates: Ukraine, Poland, Romania, Bulgaria, Portugal, Kazakhstan, Uzbekistan. Sales CRM and outreach to manufacturers
Goal: give managers one place to work with manufacturers — from the first call to the deal.
What was built: a custom CRM (Next.js + PostgreSQL): drag-and-drop deal kanban, contacts, companies, manager tasks, access roles. Loaded a base of 521 manufacturers (incl. 107 from the export.gov.ua catalogue), migrated 98 requests. Touch scenarios: call or email → presentation → quote with numbers → everything logged in the CRM. Corevia Cloud: a server for AI agents
What was built: a website for renting servers for bots and AI agents: plans, ordering, client account, full root access. You can connect ChatGPT or Claude — and the AI will set up the server itself. Gemalli: market analytics for exporters
Goal: let a manufacturer see in a minute which countries are best to ship their product to.
What was built: an analytics module — enter a product, get importing countries, import volumes and HS customs codes. Based on 458,717 records of official customs statistics across 64 markets.
