About

The person behind the code

My name is Isaac Hollow Horn Bear. I am Sicangu Lakota, originally from South Dakota, now living in Sacramento, CA. I enjoy the challenge of adapting to the ever-changing field of technology and finding unique, simple solutions — and I take pride in following through to make sure things actually get done.

“I have found a much deeper sense of self through my Lakota heritage and culture — I sincerely believe it’s what has led me to where I am today.”

That perspective shapes how I build: with patience, intention, and respect for the people on the other side of the screen. It’s also why my favorite project is Native StoryBooks — technology in service of cultural preservation.

  • Architected and built a five-application B2B SaaS platform — Scout, Focus, Lens, a self-service customer portal, and a centralized billing/provisioning control plane — delivering 215,000+ lines of production code and 1,000+ automated tests.

  • Built Lens, a natural-language-to-SQL reporting agent with live schema introspection, layered read-only SQL guards, saved reports, execution audits, and scheduled CSV delivery across SaaS and on-prem ERP data.
  • Engineered the AWS tenant lifecycle and Stripe billing system: payment-triggered EC2 provisioning, schemas/users/secrets, S3 backups, decommission/recommission, subscription entitlements, named seats, credits, and idempotent webhooks.
  • Led full-stack delivery with Laravel 13, PHP 8.5, React 19, TypeScript, Inertia, Tailwind, Pest, MariaDB, Typesense, Bash, and AWS.
