  • TypeScript serverless AWS Lambdas
  • Fastify services
  • NestJS applications supporting ASC 740 corporate tax provision calculations
• Use AI coding assistants effectively (write precise prompts, critically review AI-generated code, and apply outputs within a large multi-repo codebase).
• Write and maintain automated tests: unit, integration, E2E, and performance.
• Collaborate with architects/product teams to evolve async job patterns (imports, report generation), calculation service APIs, data layer abstractions, and observability.
• Develop, deploy, and maintain infrastructure using Terraform and AWS SAM (AWS services including Lambda, ECS, API Gateway, RDS/PostgreSQL, DynamoDB, S3, CloudFront, Secrets Manager, Route 53, WAF).
