Miguel Pires, an aspiring rocket engineer from Portugal, born in 1987 who moved to Russia early on in his life when his family emigrated.
When the apocalypse happened, he was a 30 year old Caucasian male working for Roscosmos on rocket developing. Started as a car mechanic with good knowledge on repairing them. Ended up in Chernarus a year after the outbreak after losing his family on a settlement established 200 miles away attacked by a massive infected horde not even a month before, walking all by himself with a map and compass on his hand, a backpack full of water bottles, a loaded soviet world war two Mosin rifle and a knife on his boots. When he got to Chernarus, he had no water, but enough meat for the next month - Roscosmos was considered a military branch of the army and everyone involved had good weapon and survival training.
Never being able to live near the sea before, he thought about what to do during his travel to Chernarus. Not knowing exactly what he would find when he gets there, he was already certain of something: there shouldn't be many more good car mechanics around - as officials and military had access to information during the spread, Pires was well aware of the seriousness of the situation and was still to find if he was immune to the disease, or simply pure luck of not being nearby of any source of contamination. With a small tourist map on his hands, he started pinpointing all points of interest on the location, like the biggest towns where most of the people would be making a living in, industrial areas on where he could find some remnants after the surge for scrap car and base parts, hunting sites and, most importantly to feel that he was contributing to whatever settlement would end up being built, the petrol stations where he would start to settle a shop in.
With past experience on repairing cars and building settlements, and after having one of these settlements overrun by a horde in which he detected afterward its vulnerabilities, Pires is looking forward to remake is life from scratch with the help of others, and by helping others. Not calling him by God, but by something, Pires was 50/50 between agnostic and atheist and the outbreak and humanity collapse just made him more confuse about whether someone is out there watching for us. There couldn't because he or she just allowed this to happen, but there must be because he is still alive when probably all of his over hundred of acquaintances that inhabited his last settlement are either dead or missing. Praying every day, much like a monologue of his inner thoughts, he didn't even ask for peace, because that would be just a dream - he asked instead, during all of his walk to Chernarus, that at least one person would still be alive.
