About me
I’m Dereje Seifu, a Healthcare AI Systems Architect and Software Architect based in Addis Ababa, Ethiopia (GMT+3). My specialization in Healthcare AI developed through lead technical roles on FDA-cleared AI ultrasound platforms (Healium), where system reliability, zero-downtime teleguidance streaming, and HIPAA compliance were strict safety requirements rather than optional features.
I bridge the gap between cutting-edge LLM multi-agent/RAG workflows and deterministic clinical reliability. Whether architecting multi-tenant database isolation, HIPAA compliance envelopes, or low-latency inference pipelines, I take full end-to-end engineering ownership.
Production-First Delivery
Focusing on live uptime. I write clean, strongly-typed code with strict separation of concerns, delivering production infrastructure you can trust from day one.
End-to-End Ownership
I completely manage the full tech stack including frontends, application logic, database migrations, and webhooks removing technical gaps before deployment.
Pragmatic Architecture
No over-engineering or vanity features. I map development directly to core software deliverables, providing written architectural definitions and working builds.
