Selected Work
A selection of business applications and tools I've built using modern .NET technologies
B2B portal for distributors
A closed B2B portal for a mineral water producer: distributors place their own orders, chain orders arrive from EDI automatically, and 300 hours a year of manual re-typing into the ERP disappeared.
Retail equipment tracking system
From Excel spreadsheets to a map, QR codes and the full life history of every fridge: where a unit stands, who moved it, what has been spent on repairs.
Bakery ordering portal
Daily orders from retail outlets moved from phone calls to online — together with returns accounting. The number of orders a plant can take in a day no longer depends on how many operators are on the phones.
bakery.krpk.net — bakery plant showcase site
A public showcase for a B2B bakery plant: a product catalogue you can share with a link, top items, news, a partner application form and an admin panel the company runs itself.
Pallet Mark — pallet labelling on the production floor
A WPF application that replaced handwritten sheets tucked inside a pallet with a barcode label. Who, when and on which line — a complaint is traced in minutes instead of never.
krivoozerska.ua — corporate website of a mineral water producer
Not a business card but a working channel: distributor enquiries, a coverage map, certificates, vacancies and a bilingual version indexed separately.
English Global Express API
A robust and scalable ASP.NET Core Web API backend for the English Global Express platform. Provides endpoints for authentication (JWT + Identity), user roles (Admin, Teacher, Student), homework management, file uploads, and group/classroom management. Built with flexibility to integrate a React/Next.js frontend.
