Architecting high-performance databases, optimizing queries, and building reliable backend integrations with C#.

I'm a SQL Server Specialist with over 8 years of hands-on experience in database administration, query optimization, and backend data solutions — primarily within complex retail ERP environments (Linx Sistemas).

My expertise is built on a solid technical foundation from advanced SQL Server training at Impacta (under Prof. Landry Duailibe) and deepened through real-world challenges: execution plan analysis, indexing strategies, and critical bottleneck resolution.

Currently expanding my stack by learning C# and .NET to build integrated backend tools that bridge database logic and application layer — combining T-SQL precision with clean, strongly-typed code.

• 🔭 Current Focus: Preparing for DP-300 (Azure Database Administrator) and DP-900 certifications.
• 🛠️ Building: A SQL Server monitoring tool with observability features for DBAs.
• 📚 Learning: C# fundamentals → OOP → LINQ → Dapper → Entity Framework.
• ⚡ Free time: Analyzing execution plans, studying indexing strategies, and building query practice repositories.

• sqlserver-estudos — Structured SQL Server practice repository covering T-SQL fundamentals, JOINs, CTEs, window functions, stored procedures, performance tuning, and real-world challenges based on Linx ERP scenarios.
• csharp-estudos — Progressive C# learning repository from fundamentals to SQL Server integration using ADO.NET, Dapper, and Entity Framework Core.
• SQL Server Monitoring SaaS (in progress) — High-performance tool to monitor database health, track query performance, surface missing indexes, and provide deep observability for DBAs.
