Lately, I've been spending most of my time building backend systems that are designed to be reliable, scalable, and easy to maintain.
Some of the areas I've been working on include:
β Designing REST APIs with NestJS and Node.js
β Optimizing PostgreSQL queries and database performance
β Implementing asynchronous processing using Redis and job queues
β Building secure authentication and role-based access control (RBAC)
β Integrating third-party services such as payment gateways, email providers, and video conferencing APIs
β Containerizing applications with Docker and improving deployment workflows
β Exploring AI-powered backend features and automation to solve real business problems
One thing I've learned is that backend engineering isn't just about writing APIs. It's about designing systems that remain reliable under load, are easy to debug, and can evolve as products grow.
There's always something new to learn, and that's what keeps this field exciting.
What backend technology or concept have you been exploring recently?
KathStore is an exciting E-Commerce website which reflects my technical skills. The Tech Stack I used in this project is ReactJs and Three.js (Frontend), ASP.NET Core (Backend), MySQL (Database), JWT for Authentication and Security.
I'd calculate the order total on the server from product IDs and quantities, since prices in an open cart can go out of date. Does checkout recheck both price and stock before creating the order?
