What I'm looking for

I am looking for a role that challenges me technically and allows for team leadership, with a focus on innovative solutions and continuous improvement.

I'm a Senior Software Developer with over a decade of experience in architecting and optimizing high-availability systems. My expertise lies in microservices and event-driven design, where I've successfully led teams to deliver impactful products. In my previous roles, I have managed to reduce infrastructure costs by up to 40%, all while maintaining a strong focus on code quality and agile best practices.

Throughout my career, I have worked with various technologies, including Clojure, Ruby, Elixir, and Node.js. I take pride in my ability to improve data pipelines and build robust API endpoints. My leadership experience includes guiding teams through significant migrations and optimizations, such as breaking down monolithic applications into efficient microservices. I am passionate about mentoring junior developers and fostering a culture of knowledge sharing within my teams.
