Expertise

Areas where I excel and have deep knowledge

01/

DevOps

I'm passionate about DevOps and platform engineering. I have strong experience with Azure DevOps and Pulumi for designing and deploying complex infrastructure on Azure, including managed databases such as MongoDB and SQL Server, automated backups, and secure network architectures following best practices. I also have strong experience with Terraform and GitOps using Argo CD, Kubernetes, and Docker containers. For observability and monitoring I work with Prometheus, Grafana, and Azure Application Insights. In my free time I stay up to date with the latest developments in Kubernetes, containerization, and developer platforms.

02/

Cloud technologies

Architect and run workloads primarily on Microsoft Azure while staying current with AWS and Google Cloud features to maintain a broad understanding of available options. I design secure network topologies (VNet, peering), identity and access (Entra ID, role assignments, and federated identity for secure access between third-party services and Azure), and landing zones with guardrails and compliance. I select and operate Azure managed services (Azure SQL/Managed Databases, Cache for Redis, Service Bus/Event Grid, Blob Storage) and serverless runtimes (Azure Functions) or managed Kubernetes (AKS). Governance and cost control (tagging/labels, budgets, rightsizing, lifecycle rules, Azure Policy) are part of the baseline so platforms scale without surprises. I also spend time learning less-familiar cloud resources out of curiosity and share useful findings with colleagues.

03/

Backend development

APIs and services in .NET/ASP.NET Core with clean, observable code and a long-term design vision that anticipates potential issues. I build REST services, CLIs, background workers, and event-driven systems using messaging (Azure Service Bus/RabbitMQ) and resilient patterns (retries, circuit breaking with Polly). I focus on performance where it matters, using proper caching strategies and profiling to meet system requirements. Storage choices include relational (PostgreSQL/SQL Server via EF Core) and caches (Redis). Security is addressed with OAuth2/OIDC, input validation, and rate limiting. I've worked on high-traffic, autoscaling systems and a variety of projects with diverse requirements. I primarily work with C# and .NET, and also enjoy Go for its simplicity and DevOps ecosystem. I occasionally use TypeScript/JavaScript and Python for AI workloads such as creating MCP servers or orchestrating AI agents. Testing spans unit/integration/contract tests, often with Testcontainers for realistic environments and CI integration.
