• Building and structuring web applications with .Net
• Strong relational database design, complex querying, and performance tuning in SQL Server
• Design Patterns: A deep understanding of SOLID principles and a proven track record of writing Clean Code

• Collaborator: A team-first peer who thrives on open communication and cross-layer collaboration
• We value diversity and the unique experiences each individual brings. If you’re excited about this role but don’t meet every requirement, we still encourage you to apply
