ABOUT GIANNI MASSI
I build systems that directly impact revenue and customer experience.At Massive, I\'ve built from scratch and owned critical infrastructure: billing systems handling usage-based subscriptions, data pipelines powering business intelligence, and backend services processing billions of requests monthly. A recent optimization I led eliminated 500 million database queries per month.What sets me apart is product instinct. I don\'t just write code—I understand why we\'re building it. I\'ve driven architectural decisions by analyzing customer impact, justified investments with ROI thinking, and proactively organized cross-functional alignment when I spotted gaps between technical work and business priorities.My technical foundation: Go, Terraform, PostgreSQL, AWS (Lambda, CloudWatch), and Stripe integrations. But I\'m most energized by the intersection of engineering and product—understanding what customers need, how the business works, and building the right thing, not just building things right.Previously, I led the backend and agent team at Dectar, where I coordinated between stakeholders and developers to align development priorities with business goals.Outside work: climbing, traveling Europe, and van life.
