AI Full-Stack Engineer β€’ Large-Scale Systems Architect β€’ Cloud & Distributed Systems


🧠 About Me

I architect and build large-scale distributed systems from scratch. The kind that move millions of transactions, serve thousands of locations, and run reliably under real-world load. My work spans the full stack, with deep roots in:

  • πŸ— Systems Architecture β€” distributed systems, event-driven pipelines, multi-tenant platforms
  • ☁ Cloud-Native Engineering β€” AWS Lambda, SAM, DynamoDB, serverless-first design
  • πŸ’³ Payments & Fintech Infrastructure β€” multi-processor orchestration, network tokenization, multi-tender flows
  • πŸ”— API Platforms β€” GraphQL federation, REST, schema-driven design
  • πŸ“ˆ Quant & ML Systems β€” algorithmic trading, financial data pipelines, strategy research

I've been the founding full-stack engineer who took a company from zero to Series A, and the consulting architect brought in to redesign systems at scale for Fortune-class retailers and enterprise platforms.
