Summary
👤
Senior🎓
Top SchoolBrandon Leafman is a hands-on staff software engineer and GTM-focused leader with 10 years of experience building full-stack TypeScript products and production-grade multi-agent AI systems. He was an early hire at Fluint where he designed Olli, a LangGraph-orchestrated sales AI that materially drove revenue and ACV growth by surfacing enterprise-grade context across Slack, voice, and CRM integrations. Previously he led technical teams at Built and iFIT to accelerate delivery, cut costs, and ship ML-driven personalization and marketplace features that unlocked major contracts and KPI improvements. Brandon combines product intuition from pre-seed startups to large orgs with sales and ops experience (MongoDB, Google Cloud, and a $750K painting business he scaled in college), which helps him prioritize work that delivers outsized business impact. He’s currently focused on agentic architecture, context engineering, and making AI feel like a teammate rather than a tool. Colleagues describe him as a pragmatic architect who still prefers to write production code and prototype with real data to validate product direction.
