What I'm looking for

I seek an engineering role where I can lead production-grade LLM and multimodal AI projects, prioritize compliance and observability, and deliver measurable business impact in a collaborative, product-driven team.

I am a Senior AI Full-Stack Engineer with 8+ years building scalable, secure systems across Healthcare and FinTech.

I specialize in LLM engineering, RAG systems, multimodal AI, and cloud-native full‑stack development, delivering production-grade AI integrations and AI agents that improve reliability and performance.

My work has driven measurable business outcomes: improved lead qualification by 40%, reduced service latency by 35%, processed $1.2M+ monthly via Stripe integrations, and delivered predictive models with up to 89% accuracy.

I prioritize compliance and observability in regulated environments, having built HIPAA-compliant EHR platforms, implemented audit logging and RBAC, and collaborated with product, legal, and clinical stakeholders to align AI features with governance needs.
