# Khubaib Qaiser — Senior Software Engineer (Full Profile) I own full-stack products from architecture to production. With 11 years shipping scalable web systems (React, Node.js, AWS), my recent focus has been leading AI-integrated platforms. Recently at Shopsense AI, I led the end-to-end delivery of their first LLM-powered content-to-commerce platform. I architected the serverless infrastructure (AWS CDK, Lambda) and deployed across 10+ major publishers, scaling to 150K+ daily impressions at a 0.5% CTR (5x industry standard). Previously, I architected a company-wide design system at GudangAda adopted by 40+ engineers, and built real-time logistics dashboards at STOQO. I treat AI as an execution engine within an architecture-first workflow, enforcing rigorous boundaries and test-driven reviews.
