About me
Intro
I’m a Senior Full-Stack Engineer with 9+ years of experience building and maintaining production software, with a strong focus on modern web applications and product development. My core technical experience includes React, TypeScript, Next.js and Sanity CMS, alongside experience with React Native, native Android and Shopify. I’ve worked on products for international organizations as well as startup and independent products, contributing across the full development lifecycle — from understanding requirements and shaping features to implementation, testing and delivery. I’m product-focused and enjoy working closely with Product Managers and UX/UI designers to turn ideas into useful, well-designed features. I actively contribute to feature definition, propose improvements, and provide technical and product-oriented feedback on designs and proposed solutions. Alongside my engineering responsibilities, I have also served as a Scrum Master on two projects, while continuing to contribute as a developer. This has given me experience balancing technical delivery with team coordination, Agile processes and collaboration across different roles. I enjoy working on technically challenging products where good architecture, clean implementation and a strong user experience come together. Core areas: • Full-stack web development • React / TypeScript / Next.js • Product-focused engineering • React Native / Native Android • Sanity CMS • Shopify • Agile / Scrum • Technical problem solving & code review • Cross-functional collaboration I’m currently open to opportunities where I can contribute as a Senior Full-Stack or Frontend Engineer, particularly in product-focused teams where engineers are encouraged to contribute beyond implementation.
