Hi there, I'm Matt Sergei (do call me Matt, please) and can implement your gamification project -
let's discuss first. I do have a certification for Coursera Gamification course and do research gamification trends (also part of my PhD studies on hold) yet for implementation I would use free/paid software libraries (you probably have researched yet).
Otherwise I'm software developer and wemaster for 27 years, last 7 years scripting web charts/visualizations more extensively.
Regards and hope you're safe,
Matt
