Can try outskirts of KL such as Petaling Jaya / Bangsar / Damansara. Decent tech talent here. Decent number of tech meetups. English-speaking people in general.

Honestly, KL/Klang Valley is such a gem, cost of living is super low for USD folks. Met many Americans who work on their startup/product here. Your runway extends by 4x thanks to currency exchange.

A huge number of co-working spaces around. Gyms too.
