Senior🎓
Top SchoolJoe Kalash is a Technical Lead with 11 years of experience building mobile and full-stack systems across fast-moving companies like Facebook, Palantir, Expedia Group and fintech Kroo Bank. He combines deep iOS expertise—contributing bug fixes, optimizations and Carthage support to the widely used OneSignal iOS SDK—with backend and product-facing work across large-scale platforms. A UCL master's graduate in Computer Science with a background in computer engineering, he’s equally comfortable architecting systems and shipping pragmatic fixes in legacy code. Colleagues describe his biggest achievement as surrounding himself with people smarter than him, reflecting a leadership style focused on recruiting and amplifying talent. He’s also an early adopter of clear, state-driven designs (Finite State Machine thinking) and prefers caffeine-fueled, hands-on problem solving.
