About Tushar Singh

I am a Full Stack Engineer specializing in scalable distributed systems and microservices-based architectures using.NET, Angular, and modern cloud-native practices. I focus on designing high-performance backend systems, event-driven architectures, and resilient APIs that power enterprise-grade applications. My experience spans end-to-end product development, from translating business requirements into scalable technical designs to building reliable backend services and intuitive frontend applications. Distributed Systems & Microservices Designed and developed microservices architectures using.NET Core, enabling modular and independently deployable services. Implemented Saga Pattern orchestration for managing distributed transactions across services. Built event-driven systems using Apache Kafka to enable asynchronous communication and high-throughput processing. Implemented resilience strategies using Polly (retry, circuit breaker, timeout) to improve system stability. Backend Engineering Developed high-performance RESTful APIs with ASP.NET Core, implementing API versioning, authentication, and documentation using Swagger / OpenAPI. Implemented secure authentication using JSON Web Tokens (JWT). Applied SOLID principles and design patterns (Repository, Factory, Strategy, Singleton) to build modular and maintainable systems. Leveraged advanced C# features including LINQ, async/await, delegates, generics, and extension methods. Frontend Development Built responsive applications using Angular, TypeScript, HTML, and CSS, improving UI performance and user experience. Data & Persistence Worked extensively with Microsoft SQL Server, optimizing queries and indexing to reduce database load by 40–50% and improve API response time by ~30%. Experienced with RDBMS and NoSQL data models and used Entity Framework for efficient data access. Engineering Practices Collaborated in Agile/Scrum environments to deliver scalable, production-grade systems.
