Project history
Co-founded and led technology for an early-stage venture building a private-SaaS encryption key management platform. Designed and architected the platform deployed on Kubernetes with per-tenant isolation. Filed a patent application covering the platform's core key management approach. Participated in funding conversations with investors and led product-validation discussions with design partners.
Original hire at the predecessor company (H3); maintained architecture leadership through a major merger and integration. Architected and scaled a cloud-native, multi-account AWS platform into a HIPAA-compliant, event-driven environment serving thousands of users. Led end-to-end architecture across a 10-account AWS Control Tower landing zone, built a HIPAA-compliant three-layer data lake, designed internal platform building blocks, built enterprise GenAI library (AI-Core), delivered production GenAI services, architected real-time CGM healthcare integration for ~50,000 users, designed distributed batch processing core, built governed partner data export platform, led legacy monolith migrations, built infrastructure-as-code CDK framework reducing new-service delivery time by 60%+, and established AI-native engineering frameworks using Claude Code and Codex.
Led all technology strategy and R&D for the leading Arabic health content platform serving millions of users across the MENA region. Managed distributed teams across mobile (iOS, Android), backend (C#/.NET), web, and QA. Delivered a scalable AWS platform through a successful acquisition. Built and scaled a ~25-person distributed engineering organization, architected AWS cloud platform supporting mobile apps, designed a self-serve doctor-advertising platform for 25M+ monthly visitors, launched a MongoDB-powered pregnancy companion mobile app, led native iOS and Android development achieving 4.5+ star app-store ratings, and managed technical due diligence during the acquisition process.
