About me
With over 9 years of professional experience as a Unity 3D Game Developer, I bring a wealth of expertise to the table. Having designed and developed over 50 games for various software houses, along with crafting 2 games during my university years and an additional 6 games through my own gaming company, I have honed my skills to deliver top-notch gaming experiences. My passion for gaming began at the age of 3, immersing myself in classics like Atari, Sega, and PlayStation 1. What started as a childhood fascination has blossomed into a lifelong dedication to the craft.

This freelancer really knows what needs to be done. I gave some rough data of my game's GDD so it can be balanced. As promised, in 10 days the balancing data is delivered. I need some revisions and it was delivered quickly and perfectly. Thank you for the nice experience.
