Work Experience

Squad Technologies Pvt. Ltd., Ahmedabad Dec 2023 - Present Software Developer (Backend / Asp .Net)

• Led migration of legacy backend components from .NET MVC to .NET Core, decoupling core business logic into reusable services consumed by both .NET Core APIs and the existing MVC application, improving long-term scalability and reducing tightly coupled dependencies.

• Built and enhanced .NET MVC / .NET Core backend services (C#, SQL Server) handling multi-stage financial data flows, implementing conditional fallback logic to ensure data integrity and consistent availability across dependent workflows.

• Designed and optimized SQL Server stored procedures and queries involving complex joins, conditional logic, and transactions; improved query response times by 30–40% through indexing, refactoring, and execution-plan analysis.

• Optimized backend reporting pipelines by pushing sorting and filtering logic to SQL Server, reducing in-memory pro- cessing and API payload sizes, and improving data retrieval efficiency under high-volume reporting scenarios.

• Developed RESTful APIs using ASP.NET Core Web API to securely expose backend data and integrate with React- based front ends, supporting multiple end-to-end financial workflows.

• Developed backend services to aggregate and expose payment and Direct Debit–related data, enforcing data integrity and secure access controls; implemented high-volume Export-to-Excel functionality supporting 100K+ records per export with reliable performance.

• Troubleshot and resolved production issues by debugging C# code paths and SQL performance bottlenecks, reducing recurring production incidents by ~30% through permanent fixes and optimizations. Education
