Teiva Harsanyi
I'm a software engineer specializing in distributed systems, scalability, reliability, and observability topics. I have extensive experience designing, implementing, and operating reliable systems. Meanwhile, I love meeting challenges, learning, and sharing.
My life philosophy centers around 改善 (Kaizen), meaning "change for the better". In a nutshell, it’s not important how fast you can be; what’s essential is to improve continuously. I strive to apply this philosophy to my personal and professional life, constantly seeking to learn and grow.
I have 13 years of experience, and I'm currently working at Google as a senior software engineer SRE focusing on the large-scale systems powering Google’s ML infrastructure. Previously, I worked at several companies. At Docker, I maintained systems like Docker registry, Hub, and search. At Beat, an Uber competitor, I was a staff engineer designing and operating critical services focused on reliability and observability. At Utility Warehouse, I led the transformation of the notification platform into scalable microservices, achieving a 90%+ latency reduction. At SkySoft-ATM, I worked in a safety-critical environment in the context of the Swiss air navigation service provider, where I designed, proposed, and implemented the company's central data repository used to store and compute flight events. At Axa and Airbus Helicopters, I also served as a tech lead and architect.
In 2022, I authored 100 Go Mistakes and How to Avoid Them, a well-received book (4.7/5 average rating on Amazon, Goodreads, and Manning) that has sold over 10,000 copies globally and been translated into five languages. Additionally, in 2024, I launched The Coder Cafe, a newsletter tailored for software engineers.
I'm also passionate about open-source (see my GitHub) and public speaking (my talks).
