At ROITech, I own the architecture of a multi-tenant SaaS platform, from its PostgreSQL schema and Fastify APIs to its deployment pipeline. I built production vector search and a project-scoped AI assistant with RAG, tool calling, streaming, and persistent conversation memory.
Across ROITech and freelance projects, I’ve delivered enterprise and consumer platforms using Next.js, React, and Node.js. I’ve also designed CI/CD pipelines, improved PostgreSQL query performance by 65%, and built SAP-connected applications, including a warehouse scanning platform.
