I pick the architecture that fits the problem, not the resume. Data: SQL Server (deep — query plans, indexing, memory-optimized tables, native sprocs), Azure SQL, PostgreSQL, EF Core, Dapper, LINQ.

Cybersecurity edge: self-taught since 2006; formalized through DevSecOps and 13+ certifications — Ghidra/reverse engineering, "Hack Yourself First", secure coding (insecure deserialization, XXE), Azure Security Engineer.
