I am Jeldi Kamal Kumar, a fullstack engineer with 10+ years of software experience across product engineering, fintech, and scientific systems. My work blends React and Next.js UI craft, Node.js and Python backend delivery, and a deep focus on AWS serverless architecture — Lambda, DynamoDB, AppSync, Cognito, S3, API Gateway, and AWS Amplify Gen 2 powered by CDK/SAM.

Profile
My background spans enterprise treasury platforms, fintech user journeys, scientific tooling, and internal automation systems. I value software that is maintainable, observable, and secure under real-world load.
Recent work has centered on React, Next.js, Node.js, Python, testing automation, and customization frameworks. On the cloud side I design serverless backends with AWS Lambda, DynamoDB, AppSync (GraphQL), Cognito auth flows, S3, and API Gateway — all wired together through AWS Amplify Gen 2 and Infrastructure as Code via CDK and SAM.
