About me
From polished interfaces to production architecture.
I work across the stack to build, modernize, and integrate products with complex operational requirements.
I’m a Full-Stack JavaScript Developer with 3.5 years of experience building production applications across marketplaces, booking platforms, AI products, content systems, lead-generation tools, and secure examination software. My work spans responsive React and Next.js interfaces, Node.js APIs, authentication, relational data modelling, real-time communication, payment and logistics integrations, and Electron desktop applications. I focus on understanding the complete workflow behind a product and turning it into software that is clear for users and maintainable for engineering teams.
