Benny Powers Web Developer

Jerusalem, Israel [email protected] 054-482-5726 🇮🇱 🇨🇦

A passionate, creative, and curious programmer, I specialize in Progressive Web Apps using open web standards like custom elements, shadow DOM, and service worker.

I care about F/OSS and engineering standards, preferring comprehensive solutions over band-aid hacks that add technical debt. An autodidact, my current interests include functional JavaScript, and algebraic data types.

I excel when I have a sense of ownership over my work, and when my teammates share my enthusiasm. I'm a strong written communicator, English is my native tongue. I'm also proficient in Hebrew.

Regular contributions to the OSS community are part of my m.o.; I open issues and contribute pull requests, and have released a collection of my own F/OSS web components.

You can find me in chatrooms asking questions and helping others, I enjoy being a part of a community of learners.

The company that hires me is looking for a motivated, tenacious individual; someone whose goal is to learn, grow, and produce excellent software. They value creative expression, community contribution, two-way dialogue between management and development, and view part of their job as generating job satisfaction for their team.
