Glass Health - Founding Software Engineer (Backend)
====================================================

To Glass Health:

Top 5 challenges you're likely facing & how my experience helps serve doctors & raise patient care:

**1. Scaling ML inference for API growth**: https://uncloseai.com runs community inference at scale for text, voice, TTS, & coding models. Authored "uncloseai: Machine Learning Reference Guide to Inference Clients" covering 42 programming languages & streaming techniques (websockets, server-side events). This expertise ensures Glass can deliver fast, reliable AI responses when doctors need clinical decision support during patient consultations, reducing wait times & improving diagnostic accuracy.

**2. Keeping AI outputs safe & within thresholds**: At https://coursemojo.com, kept ML algorithms on rails for 60,000+ students in public middle schools (both student & teacher-facing AI assistant). Direct experience with vulnerable populations requiring safety guardrails translates to ensuring Glass never suggests harmful diagnoses or treatments. Just as teachers trusted our AI with their students, doctors need to trust Glass with their patients' lives.

**3. Backend reliability under surge demand**: Scaled https://remind.com infrastructure (60+ microservices, 30M users, AWS: ECS, EC2, RDS, DynamoDB, CloudFormation) during COVID-19 lockdowns when distance learning demand exploded. Ensured critical services stayed online. When healthcare crises hit or seasonal illness surges occur, Glass must remain available. Doctors can't wait for downtime when patients need care.

**4. Building production Python systems**: 15+ years Python (Flask, Pyramid, SQLAlchemy, uWSGI). Built complete SaaS platforms (https://makepostsell.com, https://remarkbox.com) from database design to production deployment. This full-stack backend expertise means I can architect Glass's systems to handle complex clinical queries, retrieve relevant medical literature citations, & return evidence-based recommendations that doctors can trust & act on immediately.

**5. Complex integrations & APIs**: Recently built sandboxed code execution across 38 languages for https://uncloseai.com. Designed CI/CD pipelines & real-time websockets for classroom monitoring. Glass's API needs to integrate seamlessly with EHRs, telehealth platforms, & clinical workflows. My integration experience ensures doctors can access Glass's intelligence exactly where they need it, embedded directly into their existing tools, improving care without disrupting their workflow.
