Okay so it's hard to make a guide for a game that has everything rerolling per run, but I have advise basically. For a start when you upgrade yourself try and spread your points equally into tactics, brutality, and survival. This will give you a massive health bar which comes in handy for those cheap moments and bosses that might take you out, make sure you have an item for each part of it. So red, purple and green basically.
I managed to beat this guy on my 2nd attempt against him and the 1st was a disaster my build was awful and I didn't last very long after I got his health half way. I strongly recommend a build that uses traps alot so you can just spam them and cheap shot him when you have safe chances. Try to get the DPS upgrade that works when you are near deployed items. I think I also used the 30% additional health and 2x ammo for weapons.
Fighting this guy is pretty standard dodge a fuckton and deploy traps like its 1999. Try and be near them when you hit him to up your DPS. Video below of doing this in less than 90 seconds, it wasn't as easy as it looked but with a good build this guy isn't so bad.
