Hi, I'm Martin.
I build, scale and make things faster.

About Martin Spier

Performance Engineer @ Netflix. Advisor @ monashees+. Entrepreneur. Adventurer.

I’m an engineer, more specifically, a performance engineer @ Netflix, the world's leading entertainment service and largest single source of internet traffic in North America. I try to fill my days trying to make Netflix as fast, efficient and resilient as possible, from your iPhone client to the operating system powering all our backend services.

I've developed multiple open source tools like Vector and FlameScope, created plugins like d3-flame-graph and d3-heatmap2, and contributed inumerous other projects.

Internally at Netflix, I've created Icarus, Netflix's real-user performance monitoring solution that runs on every single Netflix device on the planet. Developed Mogul, a bottleneck analysis tool that inspects internal and external dependency demand for services and help us identify bottlenecks and tuning opportunities. Developed Slalom, a high-level demand analysis tool that helps visualize demand flow on large scale systems. Worked on metric trending that helps us identify long-term performance regressions. Developed the in-house cloud performance testing framework, analysis tool and fully automated analysis engine for performance tests.

I'm also a Venture Advisor at monashees+, one of the largest venture capital firms in Brazil, where I try to understand the tech level of prospective startups and help the invested ones to grow! Besides the portfolio startups, I advise multiple companies, of all sizes and shapes, on a varied set of challenges.

I Speak At Events

Over the last few years, I've given inumerous presentations, to groups as small as six and as large as 6,000. Most of my talks are technical and related to the work I've been doing at Netflix. I'm also known to seldomly speak on topics related to innovation, technology, engineering leadership, culture, product development, and the Silicon Valley mindset.

Besides public presentations, I also talk with companies and individual teams, locally in the Bay Area and remotely, about a varied set of subjects.

I tailor each session to the audience and strive to create the outcome you want to create!

I Adventure Around the World

I love to travel, adventure, not tourism. Getting to know new places, new cultures and new people are the most fulfilling things one can experience in life. I’ll jump into a plane or back of a truck at the smallest opportunity. Overlanding, backpacking and adventure traveling are the best ways of getting to know new places, not in 5-star hotels and guided tours!

According to TripAdvisor, I visited north of 40 countries, hundreds of places, and that's less than 20% of of the world!
