Summary
🤩
Rockstar🎓
Top SchoolDavid Felix is a Staff Software Engineer with 13 years of experience designing resilient, cloud-first and serverless architectures for startups and large enterprises. He has repeatedly led migrations and built production-grade APIs and event-driven systems using AWS (Lambda, API Gateway, DynamoDB, EventBridge), Terraform/CloudFormation, and modern stacks like TypeScript, Go, and React. As founder of NullServe he turned DevOps expertise into a product-facing GraphQL and serverless platform, handling everything from billing to video pipelines—an indicator of both technical depth and operational ownership. His background spans consumer-facing scale at Kroger and enterprise cloud architecture at Axcess and ServiceNow, with strengths in authentication, observability, and CI/CD. Based in Chicago, he combines hands-on implementation with architecture-level thinking and a genuine enthusiasm for open source and side projects. Non-obvious: he’s comfortable toggling between low-level infra (VPCs, IAM) and user-facing UX work, having shipped both backend streaming pipelines and React deployment tooling.
