Architecting the invisible
backbone of great apps

I'm a .NET developer with 5+ years of experience architecting and delivering production systems from scratch. From database design and backend APIs to cloud infrastructure, CI/CD pipelines, and deployment — I own the full lifecycle.

My core stack is C#, .NET, Azure & AWS — clean architecture, CQRS, ETL pipelines, Stripe integrations, and high-load databases like SingleStore and Elasticsearch. Currently leading a B2B platform processing 731M+ contacts.

Delivered 10+ projects for clients from Switzerland, USA, and Australia — choosing the right technologies, patterns, and infrastructure for each one.
