About me
I'm a front-end developer with over seven years of experience, working across the full software development lifecycle - from planning and architecture to deployment and maintenance.
My main focus is Angular and cross-platform mobile development. I also work with DevOps and CI/CD to improve build and release processes, and have experience coordinating work within Agile teams and mentoring developers.
As a co-founder of GGSP, I design, develop, and maintain mobile applications published on Google Play and the App Store, working closely with clients.
Outside of work, I enjoy airsoft, board games, cinema, homebrewing, and hiking in the mountains, and I'm a huge F1 fan.
