300krecords migrated
ERP & B2B platform for an auto-parts distributor
- Problem
- The whole business lived in Excel: orders, stock, invoices and finance were scattered across hundreds of sheets.
- Solution
- Designed and built an ERP from scratch: orders, warehouse & shipping, invoicing, BWA and cash-flow analytics, 17 access zones. Integrated TecCom, Buchhaltungsbutler, Shipcloud and Outlook, added AI invoice recognition with Claude API and a B2B shop with per-client pricing.
- Result
- Every order in one system, live dashboards and hours of manual work saved every day.
120orders a day
ERP, CRM, e-shop, mobile app & smart parcel lockers
- Problem
- Orders got mixed up and sometimes stolen at the warehouse, and a dedicated employee was needed just to hand them out.
- Solution
- Migrated a legacy JS/PHP system to NestJS microservices and a React monorepo with its own UI kit. Built a ~70-cell parcel locker integrated with the ERP and online store, PIN and in-app pickup, Face ID.
- Result
- Thefts dropped to zero, the hand-out role is no longer needed, and the team focuses on what matters.
100+restaurants
Ordering & procurement for restaurant chains
- Problem
- Restaurants ordered supplies by phone and chat — no single view of what was ordered, delivered or owed.
- Solution
- Joined as a backend engineer, then led the product full-stack: ordering, procurement, supplier flows and reporting.
- Result
- A single platform that keeps 100+ restaurants stocked every day.

Production management for workshops
- Problem
- Workshop owners couldn't see where an order was stuck, who was overloaded or what materials were left.
- Solution
- As CTO: architecture and launch. Orders split into stages, each worker sees only their tasks, materials are written off automatically, roles and statuses configurable per workshop.
- Result
- Real-time order status for the owner, staff and the end client — plus reports on load, delays and revenue.
FIFOcost engine
Multi-tenant financial accounting platform
- Problem
- Small businesses needed real cost accounting without hiring an accountant for every question.
- Solution
- Sales, purchases and accounting modules, FIFO cost calculation, Wildberries marketplace integration, a Telegram bot and AI-powered features.
- Result
- Companies see their real margins and stock in one place, in real time.
APIforwarder integrations
Sea-freight logistics platform
- Problem
- Finding a cheap sea-freight offer and checking the real cost against quotes was manual and slow.
- Solution
- A platform to compare and book offers, track shipments through forwarder APIs and compare actual costs with quotes.
- Result
- Faster booking, transparent costs and data-driven logistics decisions.
