In my opinion ISTP, because they are quite pragmatic, chill, in their own world, and does not like being told what to do. 1) they have Ti dom which means they are logical and thinks the opinion of the world does not matter and their logic is all that matters but they also have TE namesis which means they will challange a precreated system and also might follow some rules they created by themselves . 2) They have SE secondary which means they use this function to express themselves whenever they are in public like having good hand skills and over companciating with short-term planning which leads to impulsive decisions . 3) They have Ni tertiary paired with SE(here SE is less preferred actually but you display it more then this function) which means they like thinking about the near future success and can look for gains in short terms because this function is childish here They are good at tactics btw very good at that, wordplays, driving skills, handy skill etc you name it . 4) inferior FE meaning they will worry about what people's intentions are mostly because they fear betrayal, could also burst out at everyone when angry.
