- Ensure code quality through unit, integration, and performance testing using Jest.

- Collaborate with architects and product teams to translate business needs into technical designs.

- Participate in code reviews, CI/CD pipelines, and sprint planning sessions.

- Optimize performance, caching, and monitoring for reliability and scalability.

- Implement inter-service communication using Kafka / RabbitMQ / gRPC

- Ensure high availability, scalability, and fault tolerance of services

- Handle authentication and authorization using JWT, OAuth2, RBAC

- Design microservices-based architecture with proper service boundaries

- Apply best practices for API versioning, caching, rate limiting, and logging

- Ensure data consistency and transaction handling across distributed systems

- Participate in technical design discussions and architecture reviews

- Design and optimize databases using MySQL, MongoDB

- Write efficient queries and manage ORM/ODM tools such as Sequelize, Mongoose

- Implement migrations, indexing, and performance tuning

- Experience with Socket.IO / WebSockets

- Exposure to Domain-Driven Design (DDD)

- Knowledge of aviation domains
