Work

What we have built

Two kinds of work sit side by side at Binary Consulting: a product we own and operate, and integration programmes we deliver for enterprise clients. Each one makes the other better.

ATLAS — reservation and back-office platform

A multi-tenant B2B platform for tour operators and intermediary agencies in Serbia. Reservations, payments, fiscalisation, e-invoicing, transport modules and reporting in a single system, sold as a subscription and operated on our own infrastructure.

Multi-tenant architecture with a dedicated identity service issuing JWTs across modules
Serbian fiscalisation implemented to the letter of the law, including advance/final invoice chains and the margin scheme
SEF e-invoicing (UBL) with PDF attachment generated from the same data model
Reporting via PDF, Excel and server-side reports; bank statement import across Serbian bank formats
Progressive migration from server-side Blazor to standalone Blazor WebAssembly with PWA update flow
Operated in production: automated deployments, versioned SQL Server migrations, monitoring

BizTalk to Azure integration modernisation

Ongoing integration consulting for an enterprise client migrating a BizTalk estate to Azure. Flat-file and XML flows moved to Logic Apps Standard, with Service Bus Premium as the publish/subscribe backbone between core business systems.

Assessment of the existing BizTalk artefacts and a staged retirement plan
Logic Apps Standard architecture — flat-file schemas and XSLT without an Integration Account
Publish/subscribe integration between operations and HR systems over Service Bus Premium
Business justification documentation prepared for internal approval

Client names are shared on request, with their permission.
