Positioning

A senior technical partner for systems that cannot afford vague ownership.

Michael Ragan brings staff-level execution to fintech, enterprise SaaS, and cloud infrastructure work: designing APIs, building frontends, operating distributed services, mentoring engineers, and moving teams from cautious release cycles to daily delivery.

Selected Work

Recent systems with direct business impact.

MEMX · Lead Software Engineer · 2025-Present

IPO auction administration platform

Architected and built the backend and most of the React frontend for a greenfield platform that books, controls, and monitors live auction data against existing order book and quoting APIs.

  • Delivered in 4 months while leading the broader application portfolio.
  • Designed WebSocket streaming for auction lists, order book updates, and auction metrics.
  • Implemented Okta-backed RBAC with JWT validation, caching, and standardized API errors.
Convera · Lead Full-Stack Engineer · 2024-2025

Payment modernization and compliance workflows

Led an 8-person pod extracting payment functionality from a monolith into microservices and shipping the MVP two weeks early without major production issues.

  • Built React and TypeScript dashboards for transaction, KYC, and sanctions workflows.
  • Designed Node.js and AWS Lambda APIs handling 50K+ requests per day.
  • Improved throughput 45% by tuning PostgreSQL queries and Python data scripts.
Oracle · Principal Software Engineer · 2017-2024

Cloud platforms, support automation, and enterprise identity

Led monolith-to-microservice efforts, operated Kubernetes workloads at scale, and built systems that reduced support burden while helping product teams deploy independently.

  • Maintained production OCI Kubernetes clusters serving 10M+ requests per day.
  • Built backend automation that cut common customer support tickets in half.
  • Mentored 15+ engineers through architecture, delivery, and code review practices.
