About Chandan Singh
Lead Software Architect building cashier microservices. Scaling enterprise APIs & providing career guidance workshops.
Developing High-Volume Systems & Scaling Platforms
As a Lead Engineer at Techmojo Software Pvt. Ltd., I focus on scaling transactional microservices, cashier APIs, and secure payment integrations.
Outside of my primary systems engineering work, I run CSTutorial to provide rigorous tech mentorship. I teach candidates how to write production-grade code, dockerize microservices, and review database scaling logs.

Rigorous Technical Mechanics
"The difference between an average developer and an elite systems architect lies in their understanding of the underlying layers. Don't just import modules—know how they interact with network sockets, memory heaps, and index blocks."
I encourage candidates to write comprehensive tests, analyze profiling graphs, and explain their choices instead of relying on default templates.
