Alexander Kastil

Mastered Windows NT/2000/2003, SQL Server, Exchange Server, and Internet Information Server (IIS) foundational administration. Established deep expertise in Active Directory, database optimization, enterprise messaging infrastructure, and web server architecture. Early Microsoft certifications (MCSE, MCSA) provided credibility in comprehensive on-premises infrastructure architectures that powered enterprise operations for decades.

Evolved from SQL Server-centric backend systems to modern web application development. Led the migration from server-rendered applications to component-based architectures with ASP.NET, C#, MVC, and jQuery. Designed progressively enhanced, client-rich web applications before the modern framework era, building the bridge between traditional and contemporary web development.

Pioneered modern workplace solutions through Windows SharePoint Services, SharePoint Server, and early Office 365 adoption. Delivered enterprise-scale intranet architectures, workflow automation, and governance frameworks. Shaped digital collaboration across 15+ years and multiple platform generations—enabling organizations to integrate business processes with intelligent information management. Concluded this phase with early specialization in client-side and remote SharePoint solutions, bridging collaboration platforms with modern development practices.

Built deep expertise in HTML5 standards, Node.js, and modern frontend patterns. Adopted Angular from beta (v2) through production maturity, championing component-based design, reactive programming, and TypeScript discipline. Architected enterprise-scale SPAs, hybrid mobile solutions with Ionic, and Progressive Web Apps (PWAs). Established Node.js tooling, build optimization, and cross-platform mobile strategies that remain foundational to production front-end deployments.

Coming from a deep Microsoft 365 background, embraced an early switch to Azure as a natural evolution. When the COVID-19 pandemic emerged, was among the first and few certified Azure Developers and Azure DevOps Engineers, rapidly accumulating deep expertise across distributed global environments spanning Europe and the Middle East. Architected distributed systems on Azure Container Apps using Dapr for service-to-service communication, state management, and distributed application patterns, with .NET Aspire providing orchestration and observability across microservices. Implemented CI/CD automation and established infrastructure-as-code practices, enabling resilient, scalable applications in cloud-native environments.

Early exploration of Azure Cognitive Services evolved into AI specialization. Pioneer with Semantic Kernel for intelligent agent patterns. Early GitHub Copilot adopter advancing from agentic code assistance to in-depth agentic coding practices. 2024 formalized specialization in Agentic AI through Copilot Studio, Azure AI Studio (now Microsoft Foundry). Most recently integrating Microsoft Agents Framework into architectural patterns. Architecting next-generation intelligent systems that bridge AI-driven automation with cloud-native and distributed architectures, enabling organizations to scale expertise through multi-step agents and autonomous capabilities.
