About

I’m a Principal Engineer who turns ideas into real, useful products. I’m good at setting a clear vision and guiding teams to build things that work. I specialize in demystifying complex systems and writing clean code. I've built scalable distributed systems, intelligent, secure and multitenant control planes and various business domains related to travel, e-commerce and developer tools. I'm an active open-source contributor and advocate for collaborative, democratic software development. Currently, I'm building agentic applications powered by large language models. I'm excited about how autonomous workflows can transform how we build and use intelligent systems. Explore more about my work at: https://ayansen.github.io/
