What I'm looking for

I seek senior engineering roles where I can lead end-to-end product delivery, work with AI and cloud-native stacks, mentor teams, and build scalable, high-performance user experiences.

I am a Senior Full-Stack Engineer with 9+ years building scalable web and mobile applications, specializing in React, Next.js, React Native, Node.js, Python (Django, FastAPI) and cloud-native architectures on AWS and GCP. I focus on high-quality, maintainable solutions — from API design and database modeling (PostgreSQL, MongoDB, MySQL) to performant frontends and AI integrations.

I have led end-to-end projects including AI-powered chatbots, token analytics dashboards, and language-learning features, optimizing performance with SSR, caching strategies, and observability tooling. I collaborate cross-functionally, mentor engineers, drive technical decisions, and deliver products that blend data, AI, and real-time systems for production scale.
