What I'm looking for

I'm looking to own secure, scalable SaaS or AI-enabled products, lead architecture and delivery, and solve complex operational problems with collaborative product and engineering teams.

At Oware Technologies, I build and operate O360, a multi-tenant supply-chain SaaS platform spanning warehouse, order, transportation, inventory, manufacturing, billing, and control-tower workflows. I lead secure tenant-aware APIs and enterprise integrations with Oracle Fusion ERP, QuickBooks Online, ERPNext, Stripe, Connexis, and Injaz.

I've delivered AI-enabled products including CREChat, a conversational analytics platform for commercial real estate, and Virtuous AI, GenAI infrastructure for LLM hosting, agent workflows, vector search, analytics, and API gateways. My work spans Python, FastAPI, LangChain, React, LLM integrations, natural-language querying, and secure enterprise data access.

I also led a six-engineer team at Devsinc and modernized SaaS systems at CrewBloom, improving API performance by 40% and maintaining 99.9% uptime. I enjoy owning architecture, production reliability, cloud infrastructure, and end-to-end delivery for complex operational products.
