Hello, I'm Mubbasher Ahmed Qureshi, but you can call me Mubbi.
Principal Application Engineer & Technical Leader with 12+ years of building scalable web applications, leading engineering teams, and driving technical innovation as an ex-CTO & Co-Founder.
About me
Technical Excellence
With over 12 years in software development, I've architected and delivered enterprise-grade applications serving millions of users. From crafting pixel-perfect frontends with React and Angular to building robust backend systems with Laravel, Node.js, and PostgreSQL—I bring full-stack mastery to every project. My code philosophy centers on scalability, maintainability, and performance optimization.
Leadership & Vision
As a former CTO and Co-Founder of an EdTech startup, I've worn many hats—from defining technology roadmaps and building engineering teams from scratch to presenting technical strategies to investors. I believe great leadership means empowering developers to grow, fostering innovation, and translating complex technical concepts into actionable business insights.
Problem Solver & Mentor
I thrive on tackling challenging technical problems—whether it's optimizing database queries for 10x performance gains, designing microservices architectures for high availability, or implementing CI/CD pipelines that accelerate delivery. As a mentor, I've guided dozens of engineers in their professional growth, conducting code reviews, pair programming sessions, and technical workshops.
Continuous Learner
The tech landscape evolves rapidly, and I stay ahead by continuously exploring emerging technologies, cloud-native solutions, and industry best practices. Based in Karachi, I've collaborated with global teams and clients across diverse industries—from FinTech to EdTech to E-commerce—bringing a wealth of cross-domain experience to every engagement.
