I build high-performance web, mobile, e-commerce, and fintech products from idea to production.
KazakhstanWhat I'm looking for
I've built web and mobile products for MagnumTech, Kask Realty, TechNova, and Cloude-Tech, using TypeScript, React, React Native, Node.js, and Next.js. My work has improved bundle size by 35%, Core Web Vitals by 40%, client network latency by 50%, and order-processing time by 20%.
I take features from idea to production, including a solo-built real estate CRM and Bank Parser, a SaaS that converts US bank statements into QuickBooks-ready Excel and CSV files. I work well in remote, asynchronous teams and am available for full-time or contract roles worldwide.
