Engineering Director. Highly technical, and empathetic approach to org leadership. Deep experience in Performance, Parallelism/Concurrency, iOS, Android. Passionate about AI & ML developments, e.g. hardware accelerators, MLIR-based compilers, and generative model architectures.Started writing software for iPhone 1.0 in the last months of development. Later, honored as #15/100 “Most Creative in Business” by Fast Company. Driven by cultures that value attention-to-detail, interdisciplinary trust, and ambition to research/innovate or scale/optimize.Technical interests focus on bottom-up understanding; developed strong understanding of hardware through EE/CS and self study. Appreciate the achievements and complexity across lithography, microarchitecture, memory hierarchy tradeoffs, interconnects/serdes, and system architecture. Excited by compiler frameworks like MLIR, to enable portability and speed on increasingly special-purpose silicon.Value the concept, ‘Mechanical Sympathy’: by understanding the hardware mechanisms that execute it, software can be incredibly fast and efficient. Today, very few engineers appreciate these fundamentals. This approach has many benefits, like power/energy savings and supporting long-tail devices, and can make the newest UX feel polished on slow devices with old batteries.Yet, developer velocity is accelerated by increasingly high-level abstractions. I’m confident that software can be architected to greatly minimize abstraction cost, and embody remarkable optimizations top-of-stack developers needn’t care about.Authored and led the Texture framework. Over time it, it’s powered large parts of top apps, like Facebook, Instagram, Pinterest, YouTube, Google Search/Assistant, and more. (https://texturegroup.org/)As a director, I prioritize learning individuals’ intrinsic interests, and help them focus on their passion. I enjoy the challenge of understanding technical domains across a large space of work, and apply that knowledge to steer strategy and ensure fairness in reviews. Collaborative across disciplines, I partner closely with Recruiting, Product, Design, Program Mgmt, HR, BizDev, and Partner Engineering.Outside work I seek knowledge in home ML clusters, AI/ML research, neuroscience, biochemistry, and retro computer/console repair.Specialties: Managing eng orgs of 50-100+; Hiring, inspiring & retaining teams of high-seniority experts; Stable API design; Performance optimization; Product Design & UX; Advanced mobile development; Leading Open Source communities; Design Languages; Component Libraries.
