Projects

my name is Arbaz Khan

I’m a Senior Software Developer with 4+ years of hands-on experience designing and building backend services using AWS Serverless architecture and Node.js. My primary focus has been on developing microservices and RESTful APIs for data processing pipelines (ETL frameworks) that are efficient, scalable, and resilient. I’ve worked extensively with AWS Lambda, API Gateway, DynamoDB, RDS, S3, SQS, and SNS to build distributed systems in the cloud. I believe in writing clean, maintainable code, following best practices, and staying curious about new technologies. I also enjoy mentoring junior devs and collaborating on solutions that solve real-world problems.
