Hey, I'm Mark!

Mark Ambrocio

In 2018, I left the Active Duty Army as a Military Policeman to go full-time on my personal goals. Since then, I've pursued a degree in tech, volunteered at nonprofit organizations, freelanced, and worked on countless side projects and courses for fun. I also had the pleasure of being a founding product engineer at Wren Writing.

Founding Product Engineer

Feb 2025 – Present | Remote
  • • Built ARC delivery on production Ruby on Rails app, integrating AWS SES for custom author-sent emails and S3 for storage, with per-reader watermarking that traces any leaked copy, giving indie authors a controlled channel to share early book for reviews on book launch.
  • • Resolved client-side performance issues by isolating JS/CSS bundles across three domains, marketing, core app, and Wren Reading, so users load domain relevant assets instead of all three.
  • • Established AI-first workflows to ship features addressing underserved market needs faster.
  • • Rapidly ramped up in Go to build and deploy serverless AWS Lambdas with DynamoDB, adding features to the initial MVP that won grant funding at Southern Minnesota's startup accelerators in 2025.
