Saad Irfan

As an expert Software Engineer with over 4+ years of practical experience, I specialize in building scalable, high-performance platforms with a strong focus on developer experience and system design. Currently, I'm a Founding Software Engineer at Langbase, where I led the launch of Chai.new, an AI agent platform that scaled to 10K+ users and over 100K agents within two months. I’ve built core systems including agent lifecycle management, code versioning, LLM thread infra, multi-tenant orgs with RBAC, and API key management at scale—helping support over 500M monthly agent runs. Previously at Kyte, I worked across web and mobile to improve performance, conversion, and reliability through features like recent searches, abandoned cart flows, and cross-platform design system components. Before that, I built developer tools and content-driven apps at Rapid (formerly RapidAPI), boosting developer engagement and traffic by 300%. I'm proficient in tools and frameworks such as React, Next.js, Node.js, Express, Hono, React Native, TypeScript, Supabase, PostgreSQL, MongoDB, Firestore, and Cloudflare Workers. I also work with Tailwind CSS, Styled Components, Tamagui, React Query, Tinybird, Storybook, Figma, Segment, Braze, Strapi CMS, and Vercel. I apply patterns like RPC, RLS, and JWT-based RBAC to build secure, efficient, and scalable systems. I’m driven by clean code, performance, and building tools that empower users and developers alike.
