Built a VS Code extension in TypeScript to detect vulnerabilities in serverless functions by parsing code with regex and Babel AST, applying custom rule sets to flag issues such as hardcoded secrets, insecure IAM permissions, and injection risks, while surfacing inline diagnostics, tooltips, and quick-fix suggestions through the VS Code API to guide developers toward secure coding practices

Built RESTful APIs for chore creation, assignment, and completion, securing endpoints with JWT auth (httpOnly cookies, refresh rotation, and blacklist for invalid tokens) and middleware-based role checks for parents vs. children; modeled users, households, and tasks with Mongoose schemas, validation, and indexes to enable scalable, reliable chore tracking
