Jeffrey Bernadas
Software Engineer
I build enterprise-grade and responsive digital solutions for the web and mobile.
About
My main focus these days is building scalable, responsive and intuitive web and mobile applications.
Although I am currently employed, I am actively seeking for new opportunities to grow, learn, and contribute my expertise.
In my free time, I play Dota 2—mostly Meepo, because it helps me with my state management nightmares.
