Top SchoolAndrew Dryga is a seasoned software leader and hands-on engineer with 14 years of professional experience building scalable back-end systems, cloud infrastructure, and developer-focused tooling across fintech, SaaS, and healthtech. He’s led engineering and product turnarounds as a CTO and founding engineer—doubling revenue quickly at scale, re-architecting control planes with Elixir/Phoenix, and implementing Terraform-backed GCP infrastructure for enterprise-ready platforms. A long-time Elixir contributor, Andrew has fixed bugs and improved core libraries (Elixir, Ecto) and contributed to Erlang/OTP, reflecting deep expertise in functional, concurrent systems. He combines infrastructure, security, and UX sensibilities—shipping resilient production services (Kubernetes, Terraform, PostgreSQL, RabbitMQ) while mentoring teams in remote-first, flat organizations. Based in Mountain View, he blends startup grit with entrepreneurial product experience (from early-stage social apps to national eHealth systems) and a knack for reducing operational cost through pragmatic engineering. Notably, he began writing software at 14 and even helped streamline open-source contributor workflows for projects like Firezone, showing a taste for improving both code and community.
