Developed and maintained RESTful APIs and microservices using Node.js and NestJS

Implemented secure user authentication and role-based authorization using JWT and OAuth2 standards

Collaborated in designing asynchronous and event-driven architectures using Kafka and Redis Pub/Sub

Optimized APIs by minimizing payloads, applying encoding/compression strategies, and reducing database load through caching

Assisted in setting up CI/CD pipelines (GitLab CI) and implemented automated testing with Jest

Utilized AWS services (EC2, S3, IAM) for deployment, secure file storage, and role-based resource access

Participated in Agile meetings and cross-functional communication with DevOps, frontend, and QA teams

Used logging and debugging tools (e.g., Winston logger, Node.js debugger) to identify and resolve production issues efficiently

Worked on the Gas Exchange Platform project, specifically on the IGX-LDC Contract module

Designed and developed backend microservices for contract creation, validation, approval, and execution using NestJS and ExpressJS

Built robust APIs to manage contract workflow with role-based access, dynamic approval hierarchies, and real-time status tracking of gas trades

Leveraged Redis caching to store frequently accessed configuration data, significantly improving response latency

Implemented asynchronous communication between services using Kafka, ensuring real-time updates for trade notifications and status changes

Integrated authentication and authorization mechanisms using JWT for LDC and IGX stakeholders

Used PostgreSQL with Sequelize ORM to define complex schema relationships and stored procedures for managing transactional integrity of trade operations
