In reference of Senior Full-Stack Software Engineer Position

I am writing to express my interest in the Senior Full-Stack Software Engineer role. With over 13 years of experience building scalable web systems, headless architectures, and advertising infrastructure, I bring a proven track record of delivering robust platforms for teams across the US, the UK, and Europe.

In recent roles at dobalo and Auctus Digital, I have led engineering efforts across campaign systems, CI/CD automation, headless architectures, and production optimization for high-scale platforms.

Beyond product roles, I have spent more than a decade engineering high-traffic community platforms including VSBattles, TheCatSite, and NikeTalk — managing migrations, performance tuning, security, and monetization at scale.
