Role Overview
We are seeking a strong Full Stack Developer with hands on experience in building scalable, secure, high performance applications using .NET, React.js or React Native, microservices, messaging platforms, containers, MQTT brokers, and gRPC. The ideal candidate will have experience developing applications that require low latency, high throughput, reliable message processing, and efficient service to service communication.
This role will be responsible for designing and developing full stack solutions across backend services, user interfaces, APIs, event driven workflows, and containerized deployments. The candidate should be comfortable working in distributed systems where performance, resilience, scalability, and maintainability are critical.
Key Responsibilities
- Full Stack Application Development
- Design, develop, and maintain full stack applications using .NET and React.js or React Native.
- Build responsive, maintainable, and user friendly frontend applications with clean component based architecture.
- Develop backend services, APIs, and business logic that support scalable and high volume application workloads.
- .NET API and Microservices Engineering
- Design and develop REST APIs, gRPC services, and microservices using .NET Core / ASP.NET Core.
- Implement service boundaries, API contracts, authentication, authorization, validation, error handling, and observability.
- Build distributed backend services with a focus on reliability, maintainability, and performance.
- Messaging and Event Driven Architecture
- Develop solutions using Kafka, MQ based messaging systems, and MQTT brokers.
