Hi thereπŸ‘‹ I'm Agrima Saxena

Software Engineering Β· Backend Systems Β· Applied AI Β· Cybersecurity

I build backend platforms, full-stack products, applied AI systems and security-focused software with an emphasis on measurable performance, reliability, auditability and production-minded engineering.


πŸ‘©β€πŸ’» About Me

Girl Coding Animation

I enjoy working on software where backend engineering, applied AI and security intersect with real product problems.

What interests me most is not simply getting something to work. I like to understand:

why it works, where it can fail, how it behaves under load and what would make it easier to trust.

That usually leads me toward problems involving APIs, distributed services, intelligent systems, security controls, data pipelines, testing and performance optimization.
