I have 2 years+  professional experience working on paid projects. 
1 project ive worked on was my own: Blockouts, which could be found on googles app store for mobile
another is with T4T games working on their turn based RPG game ACRAS* (release: TBA)

Ive worked in group settings, making use of discord,trello and use github and git kraken (and others) for repositories/gui amongst the team.

After creating working prototypes of most game genre types (all  2D as GMS is primarily used for) with clean,commented and easy to read code; I feel confident that I could complete the coding requirements for whatever project you have in mind.  

 I look forward to working with you and/or your team!
