What I'm looking for

I am looking for a role that fosters innovation, collaboration, and continuous learning in AI and machine learning.

As an AI Architect with 8 years of experience, I have pioneered enterprise-grade LLM platforms that enhance educational assessments and personalized tutoring. My expertise lies in dynamic model routing, secure RAG systems, and resilient agentic workflows, which have been instrumental in optimizing cost and latency for over 30,000 students globally.

At Cognii, I led the development of a multi-LLM inference engine that maintained a 99.9% uptime during peak demand, while also scaling multilingual content moderation to over 30 languages. My commitment to innovation is reflected in my ability to integrate advanced technologies like n8n for automated workflows, significantly improving incident response times and operational efficiency.
