About Me

Portrait of Mayank Singla

Hi there! I'm Mayank — a Software Developer who likes shipping things that scale.

I hold a B.E. in Computer Engineering from Thapar Institute of Engineering & Technology, with a foundation in Web Development, Data Structures & Algorithms, Database Management, Computer Networks, Network Security, Secure Coding, Cyber Forensics, and Ethical Hacking.

Today I work across the full stack — designing scalable backend architecture, building CRM and payment integrations, and leading delivery — while keeping a hacker's eye for how systems can break.
