I’m a Senior Full-Stack Developer with 6+ years of experience, having delivered 10+ production-ready web and mobile applications - from MVPs to scalable SaaS platforms. I’ve contributed to products used by thousands of users, while improving performance, stability, and overall system quality. My focus is not just writing code, but building solutions that deliver real business impact. I’ve worked across the full product lifecycle - from rapid MVP development to scaling and maintaining live systems. I’m comfortable taking ownership of features, improving existing architectures, and turning complex requirements into clean, maintainable solutions.
