At KMC Solutions, I build AI chatbots and client-facing pharmaceutical SaaS features, including streamed WebSocket responses, conversation persistence, citation parsing, and a Knowledge Graph UI for complex data relationships. I also drove V1-to-V2 infrastructure migration work and built internal data-collection dashboards.

I've delivered responsive web systems across education, finance, e-commerce, and business operations as an independent contractor, and contributed React and Laravel API work at Supsoft Tech. I enjoy turning technical requirements into polished interfaces, reliable workflows, and deployable full-stack products.
