Freelance D3.js Developer - Micheal Edekin
Freelance D3.js Developer

I started out as a Structural Engineer, graduating from UNIBEN, finishing among the top 5 in my class, before taking a path that led me deep into the world of AI/ML Engineering. That transition wasn't linear, it was built on exposure, experimentation, failure, and a lot of learning along the way. Through it all, one thing has never changed: I'm most alive when I'm at the intersection of technology and real world problems. Growing it, evolving it, building it, scaling it. That obsession has shown up in the work, from building the first-ever AI-powered RFP at TalkDEI, to finishing in the top 5 globally at Hamoye, to consistently scoring 98/100 on technical assessments. I've also had the privilege of mentoring and teaching over 5,000 individuals across various skillsets.

Freelance D3.js Developer - Paul Gasbarra
Freelance D3.js Developer

Hi there, I'm Paul. I live in New Jersey. I’ve been a developer for 9 years now. I came to software development because I love to create things. I love it when people use those things, and I love it when those things help people. I come from a creative writing background which is very different from software development but there is a lot of similarities between a well crafted piece of writing and a well crafted bit of code. Since I began coding, I’ve built digital museums, multi-device shopping experiences, commuter facing kiosks, and mall directories. I want to keep on building really cool and useful things, share my knowledge with others. I'm well versed in Javascript, Typescript, React, Redux and associated Front End technologies. I can't wait to help you out.
