What I'm looking for

I’m open to Senior .NET, Staff Engineer, and AI-integrated systems roles that are 100% remote worldwide, as well as international relocation.

At Dexian, I architect and deliver microservices and background workers powering Home Depot’s inventory, order processing, and supply chain workflows. I’ve also diagnosed systemic failures across distributed services and helped restore stability to critical pipelines.

With ProcessIA, my B2B SaaS, I’m building an AI platform that processes legal documents through OCR pipelines, LLM analysis, and structured reports. I bring enterprise .NET engineering together with AI systems, including RAG pipelines and production API integrations.
