Senior Software Engineer (SE-3) Thales Group Aug 2024 – Present Backend Platform & Cloud Services Noida, India

• Designed and shipped RESTful APIs in ASP.NET Core using Controller–Service–Repository layered architecture with Dependency Injection, enabling clean separation of concerns across [N] production services.

• Implemented JWT-based authentication and role-based access control (RBAC) across protected endpoints, hardening the platform's security posture and standardizing identity for [N+] internal users.

• Integrated services with SQL Server via Entity Framework Core (code-first), optimizing data access with LINQ queries, transactions, and indexed lookups — reduced query latency.

• Applied SOLID principles and Clean Architecture patterns to refactor existing modules, improving testability and cutting onboarding time for new engineers on the codebase.

• Architected and deployed scalable, secure workloads on AWS (EC2, VPC, RDS, FSx, Active Directory) with Terraform-managed infrastructure, improving deployment repeatability and reducing environment drift across [N] environments.

• Built interactive dashboards in JavaScript for real-time monitoring and visualization of key operational metrics, enabling product and ops teams to self-serve insights.
