I’m a senior full-stack software engineer and AI-focused architect with 11+ years of experience building and launching complex AI-powered platforms and large-scale automation solutions. I specialize in full-stack development, RAG pipelines, multimodal AI workflows, and secure, compliant data handling—turning technical prototypes into reliable production systems. Across my roles, I’ve led architecture, release, and performance initiatives—improving Google Lighthouse scores from 78 to 92, scaling high-traffic web apps to 18,000+ daily active users, and improving operational success from 87% to 95% through robust backend design. I build secure systems end-to-end, integrate third-party APIs, and deliver practical AI features (like document processing with high field accuracy and smart listing assistants) that measurably reduce manual effort and support friction for real users.…I’m a senior full-stack software engineer and AI-focused architect with 11+ years of experience building and launching complex AI-powered platforms and large-scale automation solutions.
