Senior System Architect and AI product builder specializing in multi-tenant RAG platforms.
What I'm looking for
I’m a Senior System Architect & AI Product Leader with 15+ years of experience engineering high-scale, multi-tenant SaaS and RAG-based AI platforms. I bridge complex distributed systems with business objectives, focusing on production-grade architectures.
My work emphasizes data isolation, low-latency performance, and cost-efficient scaling. At Tiered Communication Services, Inc., I architected Utilen, a high-performance multi-tenant AI SaaS, implementing a RAG-based knowledge system with Qdrant and AWS S3 to deliver workspace-level data isolation.
I also optimize real-time query processing across distributed systems, reducing retrieval latency for large-scale datasets while maintaining high availability. Beyond AI, I’ve built full-stack experiences for multi-platform products, spearheading social media and video streaming across Web, iOS, and Android.
Recently, I’ve added an educational and mentorship focus as an Adjunct Lecturer at Eastern University, teaching software engineering grounded in real-world system design and AI-driven applications. Previously, as Sr. Software Engineer & CTO at Eleven Media, I led technical roadmaps and backend overhauls to achieve 99.9% uptime and stronger reliability during peak loads.
