​​Hi, I will be your next fullstack software engineer. I have worked with businesses across a few industries, serving 2,000+ users, and my contribution to these projects generates early-stage recurring revenue. I specialize in building high-performance mobile and web applications using React Native, Next.js, and modern backend systems Nodejs. From idea to launch, I handle the full development lifecycle architecture, development, deployment, and scaling, delivering fast, reliable, production-ready systems. On some projects I worked as the CTO and lead developer, I will also help you plan the product and make good technical decisions, not just write the code. I care deeply about performance, accessibility, scalability, simplicity, and clean code.

I spend time learning through reading and courses, constantly improving my skills and staying up to date with new technologies. Outside of work, I enjoy playing the piano and bass guitar, and I naturally enjoy researching and understanding how things work. Thank you for taking the time to read my profile, I look forward to the opportunity to work with you.
