At Arobid, I engineer hybrid search and indexing for Deep Search, RFQ Buyer Matching, and product and supplier discovery across 5M+ RFQs and 2M+ products. I combine vector search, BM25 retrieval, structured filters, and reranking.

I also built structured query parsing that raised RFQ translation accuracy from 78% to 100% on a 350-sample evaluation dataset. My work includes AI onboarding workflows that automate company onboarding for 5,000+ businesses.

At HiliosAI, I engineered an omnichannel conversational AI interface and a multi-turn agent with escalation rules and human support transfer. I also built landing pages and lead workflows that achieved a 100 Lighthouse SEO score.

Earlier, I developed Vue and TypeScript features for OTBZone’s e-commerce platform and modular micro-frontend apps at LTV Software Co. I’ve also led frontend development for OASIS, reducing its bundle size by about 687 KB through route-level code splitting and lazy loading.
