What I'm looking for

I'm seeking senior roles to architect scalable web and mobile products, lead and mentor teams, apply modern JS, Python, cloud and AI integrations, and improve CI/CD and testing in collaborative, growth-oriented companies.

I am a Senior Full Stack Engineer with over 10 years building modern, scalable web and mobile applications using React, Next.js, Vue/Nuxt, React Native, TypeScript, Node.js, and Python. I design full-stack architectures, microservices, and APIs, and I deploy reliable systems on AWS and GCP using Docker and Kubernetes.

At Notion and previous companies I led engineering efforts that supported millions of transactions per month, reduced deployment times from hours to minutes, and delivered features adopted by tens of thousands of users. I mentor developers, champion testing and CI/CD best practices, and integrate AI (OpenAI API, LangChain) to drive product innovation and exceptional UX.
