Senior full stack engineer who builds web and mobile products from initial architecture through delivery, with a background that includes technical leadership, software architecture, and serving as a CTO.
Architected external PII storage, an AWS SQS synchronization pipeline with dead-letter queueing, and multi-layered Cognito and AppSync access control so sensitive student data never lives in the primary database or leaks to unauthenticated therapy sessions.
Built two production LLM workflows on AWS Bedrock and Gemini: multi-page visual story generation with persistent character context, dynamic student questions, and real-time SSE streaming, plus schema-validated clinical progress reports linked to source sessions.
A static, recruiter-focused portfolio and résumé pipeline where a local-only Keystatic editor writes validated YAML and Markdown files that build into plain HTML and a matching résumé PDF.
