Sup, Kirill here ⌑

I build things. Sometimes they work.

✍️ Occasionally writing about frontend on Medium

🤖 `AI` _{trying to use it before it uses me}	💳 `FinTech` _{payment flows that don't make users panic}	🧪 `Testing` _{really complicated relationship. working on it}	🧰 `CI/CD` _{teaching GitHub Actions to judge my code before people do}	🌍 `Intl` _{the browser speaks 200+ languages. I just take the credit}
📦 `NPM` _{if I solve something twice, it becomes a package. can't help it}	⚡ `Performance` _{trying to understand the bottlenecks before blaming React}	📋 `Forms` _{multi-step, robust, usable. what did you expect?}	🎨 `CSS` _{tokens, components, and the occasional argument with Figma}	🧑‍🏫 `Mentoring` _{explaining React until it finally explains itself}

Small frontend tools, UI primitives, and tiny attempts to make developer experience less annoying.
