Senior🎓
Top SchoolGustavo Maciel is a Senior Principal Software Engineer based in Sydney with 13 years of experience building games and large-scale software, currently leading engineering efforts at Atlassian while still developing games through Melting Logic. Self-taught in game programming from childhood, he blends deep mathematical tooling and creative design to ship visually striking games and robust platform features. At the open-source level he has enhanced libGDX’s math and geometry capabilities—adding ray-AABB intersections and derivative support for splines and Bezier curves—demonstrating a knack for low-level, performance-sensitive systems. His career spans hands-on roles from backend engineering to principal architecture, delivering across mobile, desktop and web platforms. Colleagues describe him as a challenge-seeker who pairs technical rigor with an appetite for novel mechanics and graphics innovations.
