Hello, I'm
Kushagra.
Java Backend Engineer · Software Engineer · System Design Enthusiast
I build backend services with Java and Spring Boot, work with relational databases and cloud infrastructure, and enjoy understanding how software systems behave under real-world constraints.

03 / How I think about software
Beyond frameworks.
Into behavior.
I enjoy going beyond frameworks and understanding what happens underneath them.
Reliability
What happens when something fails?
Scalability
What changes when traffic increases?
Performance
Where does latency come from?
Maintainability
How should APIs and services evolve?
Security
How can the system be abused?
Observability
How do we know what is happening inside?
04 / Technical ecosystem
Tools are useful.
Understanding is better.

07 / Security-minded engineering
Build.
Then harden.
My Cyber Security & Digital Forensics background informs how I think about backend systems: understand the attack surface, validate assumptions, and make secure behavior part of the design.
