Key Responsibilities

Front end

  • Implement modern React interfaces using hooks, SSR or SSG, and progressive enhancement
  • Build accessible and performant UI with Tailwind CSS and clear component patterns
  • Maintain type safe view models and shared UI utilities

Back end

  • Create API first services using REST, GraphQL, or tRPC with OpenAPI documentation
  • Deploy serverless functions on Cloudflare Workers and AWS Lambda
  • Integrate storage with S3 or R2 and implement authentication and authorization with AWS Cognito

AI features

  • Implement retrieval augmented generation using vector indexing over documents, screenshots, videos, and metadata

  • Implement monitoring, tracing, and logging. Establish SLIs, SLOs, and error budgets. Track performance budgets and enable automated alerts, controlled rollbacks, and post incident reviews within CI or CD workflows.
