Freelance Ruby on Rails Developer - Ikechukwu Orji
Freelance Ruby on Rails Developer5.0 (143 reviews)

I dwell in the midst of complex problems. I make my bed with solutions to problem. Have built solutions ranging from complex stocks management system with realtime stock data synchronisation to web applications that manage and analyse user data in their millions. In summary, I love seeing problems solved. I am also a debugger tool (kind of) and a teacher. I spot and easily detect bugs lurking in your code within minutes. I specialised in Javascript, but you would find me working with ruby, python, Go and even dart. Would love to help out with your project and help you find those solutions that have proven difficult, together we can bring walls down.

Freelance Ruby on Rails Developer - Jon Chui
Freelance Ruby on Rails Developer

I'm Jon and I love mentoring junior engineers! For 10+ years I lived & breathed 📱mobile.. worked on top 10 App Store apps (Google Maps, Gmail, Google search) as well as a bunch that didn't see the light of day. The pressure took it's toll finally & I followed the "burnout track" and took 6 month sabbatical (that would later turn into almost 3 years). My family & I left the bay with 8 suitcases of all our belongings, and i thought tech would only be in my rear view mirror... I exchanged the standup desks & nap pods of silicon valley to serve families in the slums of Philippines & Cambodia. To my utter surprise and delight though, these families were happier than I was. Something was missing? We came back to the mainland & I tried my hand at using tech for good, by working on the "strava for sobriety" app and it was amazing. I was finally helping ppl again! But as w/ many startups, funding fell through... I then went to help a big, well-funded startup who's goal was "tech for good", specifically in non-profit church space. I was so excited! And somehow, in the midst of "strat sums" and super fun budgets I lost my way... I actually kind of lost heart.
