👋🏾 Hi, I’m Hayatu
I design and build frontend systems, not just products. My focus is on creating reliable user-facing experiences and the internal platforms that support them — systems that scale, improve developer experience, and help teams move faster with confidence.

Recent work
- ● At X-HR Labs, I worked on frontend systems and internal platforms for an AI-native HR product, focusing on shared tooling, scalable UI infrastructure, and developer experience.
- ● At Tamara, I contributed to large-scale fintech systems used by 10+ million customers, working on high-traffic user flows, internal tools, and partner platforms with a strong focus on reliability and performance.
Other products I’ve helped build
Tools
- ● JavaScript, TypeScript, Node.js
- ● Vue.js, React, Next.js, Nuxt
- ● GraphQL, REST APIs, real-time systems
- ● AI tools such as Cursor, Anti-gravity, and Claude — used directly in the build loop for writing and refactoring code, exploring implementations, debugging, and accelerating delivery.
Writing
Misc
- ● I love video games though I have less time for it these days. The one I'm currently playing is FIFA on PS5.
- ● I like to read sometimes, mostly psychology and history. But I read practically everything.
- ● I was a graphic designer for about 2 years and then a product designer for a year before transitioning fully into software engineering.
