My CV
I am an engineering leader with a proven track record of managing cross-functional teams of engineers and a second-layer of engineering managers. At the age of 23, I co-founded a software development company, where building a strong team of engineers and designers and managing clients has given me strong business and product acumen. I’ve been developing for iOS (both Swift and Objective-C) for 12 years, for backend with Ruby on Rails for 6 years and Kotlin for 2 years. I’m familiar with various frontend and backend stacks. I’ve released close to 10 apps and websites, designing and coding the entire stack by myself.
My last stint was at Delivery Hero, world’s leading food delivery company, where I managed an organization of 2 teams with 20+ employees.
Collaboration?
Do you need help with your mobile app or your website? Or do you need a teammate with tech and product leadership experience? Or are you a fellow software engineer in need of some help?
You can hire me as a contractor, full-time employee or an advisor or mentor.
