Full Stack Developer

Saayam For All Sept 2024 - Present
Building the cloud foundation and AI workflows that power Saayam's MVP.
  • Designed and deployed request-handling microservices on AWS Lambda and Spring Boot. Each service cold-starts under 400 ms in load-test runs.
  • Implemented a FastAPI plus Airflow reporting pipeline with GPT-4 summarizer, that snapshots operational data every hour for product stakeholders.
  • Integrated Amazon Cognito RBAC so new volunteers authenticate with Google or email in less than thirty seconds.
  • Documented the event-driven architecture with diagrams and ADRs which now guide all new contributors.
