Internship

99X•Sri Lanka

Built features for an enterprise commercial compliance management platform using TypeScript, React, Angular, and AngularJS.
Translated client requirements into user stories, working directly with product owners to scope and prioritize features.
Replaced hardcoded and console-visible Lambda environment secrets with a runtime resolution pattern, closing a security gap where anyone with console access could view sensitive values.
Built Node.js services with AWS Lambda against MongoDB/DynamoDB and integrated AWS (ECS, S3, Cognito).
Optimized database migration scripts by batching writes, reducing peak CPU utilization from 100% to under 50%.
Automated API testing (Postman) and E2E testing (Cypress), reducing manual QA effort.
