I feel the reason we don't know anything about her is that it will be a big reveal. The backstory of Madi and where/when she meet Clarke will be revealed in season 5.

My theory is that Clarke searched the area around Arkadia and Polis for life, and even areas we've never screen. After realizing no one survived the death wave and not being able to contact the bunker or the ring she believes everyone is dead. Clarke then decides to commit suicide, and goes to gather supplies to hang herselp. However while doing so she finds Madi and then she finds purpose to keep living.
