I'm a senior frontend engineer with 7+ years of experience in building webapps, 5 years in crypto. The most recent project was a perpetual DEX - this is the work I'm most proud of (https://t.me/yo6762e/3 - video in a public Telegram channel).
I can either migrate legacy codes or build 0-to-1 SaaS products/fintech platforms.
I'm exploring opportunities to work in non-crypto space. What I can bring:
- Hands-on execution: Deep expertise in React, TypeScript, and modern frontend tooling.
- Scalable Engineering: I focus on robust, clean architecture. I drive maintainable codes that scale.
- Product-Minded Autonomy: I build features from technical design to deployment. I obsess over UI polish, intuitive UX, and the end-to-end UX.
- Async & Remote Efficiency: I rely on clear, asynchronous communication to keep projects moving without endless live meetings.
I'm looking for a job that needs a strong frontend engineer: either a senior frontend role, or fullstack nodejsproduct engineer role. $3-5k/month. Remote only.
