À propos de Haroun
I help startups and companies design and build AI/LLM-powered applications: RAG pipelines, FastAPI microservices, and full-stack dashboards (React/Next.js + Tailwind).
With experience in a YC-backed startup (Nexus), public sector modernization (DB2 migration, APIs), and medical AI research (CNN, imaging), I combine hands-on engineering with product thinking.
My focus: ship fast prototypes, scale reliable pipelines, and bridge AI research with productio
