I focus on architecting performant APIs, leading feature development for fintech and sustainability platforms, and delivering data-driven solutions for global clients through cross-functional collaboration. In my recent roles at Altruistiq, Tkxel, and Block SW, I've shipped backend-first initiatives, from data ingestion workflows and emission-factor customization to high-throughput fintech backends and AI-powered tools. I thrive on turning complex requirements into reliable, scalable software and enjoy mentoring teammates to achieve measurable impact.…I'm Muhammad Zain Ul Abideen, a Senior Software Engineer with over 5 years of experience building scalable backend systems using Node.js, TypeScript, and AWS.
