Krishna S

I'm a senior software engineer focused on building reliable, user-friendly web applications and internal platforms at enterprise scale. My strength lies in bridging frontend UI/UX thinking with practical backend system design — creating interfaces that are simple for users and systems that are solid underneath.

I work primarily with Angular, Node.js, PostgreSQL, and AWS, and I enjoy solving problems around performance, scalability, maintainability, and complex workflows. I'm comfortable owning features end-to-end — from UI design to API development and cloud deployments — while collaborating closely with designers, product teams, and stakeholders.

Outside of software engineering, I explore street photography and personal creative projects which continue to shape my visual design sense and attention to detail.
