What I'm looking for

I’m looking for a role where I can own system architecture and delivery end-to-end—building scalable mobile and backend solutions, integrating payments, and shipping AI-driven improvements. I’m open to remote work, travel, and relocation, with a reliability-first mindset.

I build end-to-end products with a focus on reliability, efficiency, and real-world business impact. I’m a Senior Full-Stack Engineer specializing in Flutter (iOS/Android) and scalable backend systems (PHP, Node.js), delivering high-load, real-time platforms used in production.

From MVP to scalable production, I design system architectures, optimize performance, and lead delivery across concurrent initiatives. I’ve shipped fintech integrations and automation, including customer support systems supporting 500+ operators and 10k+ daily interactions, and AI-driven applications in production like an AI-powered children’s story generator.
