What I'm looking for

I seek senior engineering roles building scalable web platforms, emphasizing clean architecture, automated testing, CI/CD, and collaborative, growth-oriented teams.

I am a Senior Software Engineer with a decade of experience designing and implementing robust web applications across multiple industries, focused on clean code, system architecture, and optimizing development pipelines.

At Unite Us and ShopKeep by Lightspeed I built scalable full-stack systems using Python (Django) and Ruby on Rails, migrated monoliths to microservices, improved performance and test coverage, and implemented CI/CD and automated testing to reduce production bugs.

I collaborate effectively with distributed teams, drive maintainability through reusable components and modular architectures, and continuously seek to improve deployment efficiency, observability, and developer experience.
