Who I Am

The engineer
behind the stack

Vedant Kale

I'm a Backend Engineer who enjoys building APIs, backend systems, and full-stack web applications with Node.js and Express.js.

I started programming through self-learning and naturally gravitated toward backend development. I enjoy designing clean architectures, solving complex problems, and figuring out how systems work behind the scenes.

Many of my projects are inspired by real-world challenges I've encountered firsthand, which is why I focus on building software that is practical, reliable, and genuinely useful. I believe good software should be simple to understand, easy to maintain, and built to solve real problems.

Debugging April 2026
Fixing Circular Dependency Issues in My Node.js + Express API Project

Discovered and fixed a circular dependency issue in my Node.js + Express API caused by barrel exports. A practical breakdown of the debugging process, root cause, and architectural changes that made the codebase more predictable and maintainable.
