Selected Work
A selection of business applications and tools I've built using modern .NET technologies
Universam — loyalty program for a regional retail chain
A loyalty app for a regional 7-store grocery chain: points, checkout redemption, weekly deals and personal offers.
RMT Suite — distribution analytics and merchandising platform
An in-house sales analytics and merchandising platform for a mineral water producer, replacing a ~$10,000/year SaaS subscription.
Kyros — internal document approval system
An internal document approval system for a company running offline, with no domain controller and no per-user subscription.
KRPK Bakery App — mobile ordering for a bakery's retail partners
A mobile B2B ordering app for a bakery's retail partners: daily orders, one-tap reorder, returns and deals.
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.
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.
KRPK Fleet — route, driver and fleet scheduling
Route, driver and fleet scheduling for a bakery, moving replacement know-how out of people's heads and into the system.
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.
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.
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.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.
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.
