Azure integration platform connecting the company's business systems (ERP, PIM, central data hub) with internal consumers and external partners. Decision point on Azure alongside the solution architect. Migrated on-premises enterprise services to a fully event-driven Azure architecture: ~30 Function Apps and hundreds of Logic Apps integrated via Service Bus, with independent per-service deployments. Built the two-way product data integration between the central data hub and the PIM: event-driven delta sync over Service Bus queues orchestrated by Logic Apps, plus a file-based full load, thousands of product updates a day and 50-60k on bulk updates. Built the EDI integration with an external B2B provider end-to-end: scheduled Logic Apps driving a Function App that exports orders, invoices, products and company data as CSV files of up to millions of rows, delivered over REST through API Management. Ran API Management as the single gateway for ~20 APIs: one Entra ID app registration per consuming system, JWT validated in inbound policies; OpenAPI specs on every Function App. Connected the platform to on-premises with Azure Hybrid Connections and the On-premises Data Gateway. Replaced manual deployments with Azure DevOps pipelines driven by ARM templates and per-environment parameter files. Daily use of AI development tools (Claude Code, GitHub Copilot, ChatGPT).

Sole backend owner of a cloud-native B2B product configurator and pricing engine used by international distributors to configure products and stream validated orders into the corporate ERP; owned the full lifecycle, from architecture and implementation to multi-environment deployment. Built and shipped a fully documented REST API from scratch on .NET Azure Functions with Entity Framework Core and Azure SQL, deployed automatically across Dev, Training and Production. Secured access for international sales regions with scoped, role-based JWT tokens: a custom Azure Functions middleware pipeline for token validation and global error handling, with Microsoft Entra ID and Microsoft Graph behind a two-layer RBAC (role at the gateway, ownership checked on every record). Automated the ERP fulfilment pipeline end-to-end: Service Bus queues for order upload and email dispatch, CSV exchange with the ERP over OneDrive and Azure Files, and a runtime dual data-source factory switching between SharePoint master data and the SQL draft copy.

Integration layer between the firm's internal business systems (leads, orders, clients) across departments, replacing a slow, error-prone manual data replication process. Eliminated the manual replication and the human errors that came with it by designing, together with the lead and the architects, an automated event-driven integration layer between every system that needed the data. Built the integrations on Logic Apps and Service Bus, with Function Apps only where transformation logic needed code, and dead-letter handling with reprocessing for every failed message; secrets in Key Vault, Redis caching, observability through Application Insights and Log Analytics. Co-built the Terraform codebase that provisioned nearly every Azure service behind the integration layer, reproducible across environments instead of assembled in the portal.
