Experience
Ninjio — Remote (Los Angeles, CA)
2026 – Present
Full Stack Engineer
- Lead engineer on Ninjio Sensei AI, a generative-AI platform that turns a prompt or uploaded document into a fully narrated, interactive security course — delivered 95 tickets across a new 14K-line Django app (20 service modules, 36 migrations) and a 5K-line React/TypeScript authoring wizard, shipped to production in both US and EU regions.
- Architected the generation pipeline end to end: document text extraction, opt-in web-search enrichment, and slide synthesis on OpenAI with an Anthropic Claude fallback, composing decks from 19 layout templates with assessments grounded in the taught content.
- Integrated ElevenLabs text-to-speech for per-character narration with word-level caption synchronization, per-character voice tuning, randomized narrator pools, and in-app upload, recording, and trimming of custom audio.
- Shipped multi-format delivery — self-contained SCORM packages for external LMS platforms, standalone HTML, and MP4 video export rendered through headless Chromium on a dedicated Celery queue.
- Built Remix (localize a published module into any of 8 languages, edit in place, or fork to a new draft) plus per-customer branding, usage-token metering, and feature flags resolved through the tenant hierarchy under strict multi-tenant data isolation.
- Backed the platform with 985 automated tests and owned release engineering: production ECS deployments, CI guards on the migration graph, and root-cause diagnosis of cross-region deployment failures.
