About
Hi, I’m Rehan Qasim, a full-stack software engineer based in Karachi, Pakistan. I thrive on taking products from zero to production and owning them through to measurable outcomes. I’ve led the development of multi-tenant SaaS platforms, replaced expensive external vendors with in-house solutions, and steered flagship redesigns that simplified navigation and set new internal standards.
I enjoy collaborating across web, iOS, and Android teams, with strengths in architecture design, AI-powered features, and cross-functional execution. My work spans React, Node.js, Python, Ruby, and cloud-native stacks on AWS and Supabase, always aiming to ship reliable software that delivers real value.
