Architecture & Development 
Design and implement a serverless, microservices-based architecture on AWS. Build secure and scalable backend services and APIs using Node.js and TypeScript. Integrate multiple data sources such as PostgreSQL, DynamoDB, ElasticSearch, S3, and various unstructured data sources via GraphQL and REST APIs. Contribute to all phases of the development lifecycle – from design through deployment and monitoring.

Collaboration & Agile Work
Work closely with cross-functional teams (frontend, product, QA, UX) in grooming, planning, code reviews, pair programming, and knowledge-sharing sessions. Translate business requirements into technical specifications and help prioritize and manage the backlog. Participate in daily standups and actively contribute to achieving your team’s sprint goals. 

Cloud & DevOps (AWS Focus)
Work extensively with AWS services including Lambda, ECS, RDS, API Gateway, IAM, S3, and more. Support CI/CD pipelines and infrastructure provisioning with tools like Terraform and Bitbucket Pipelines (or GitHub Actions). Maintain system availability and performance using monitoring, metrics, and alerting tools. Troubleshoot and resolve incidents across environments and services, owning your work end-to-end.

Ownership & Continuous Learning
Take ownership of your systems and code – if something breaks, you’re there to help fix it. Proactively identify opportunities for technical improvement and scalability. Stay current with industry trends, tools, and technologies – especially in cloud-native development and AWS. Share learnings and foster a culture of engineering excellence within the team.
