ABOUT ME
MY STORY
I'm Hasintha Pasindu, passionate about building reliable systems and automating infrastructure. I focus on keeping services running smoothly, whether that's through CI/CD pipelines, monitoring, or cloud automation.
My journey started with Linux system administration and evolved into cloud infrastructure, deployment automation, and system monitoring. I believe in learning by doing—building projects to solve real problems and keeping production systems healthy.

PRINCIPLES I WORK BY
AUTOMATE EVERYTHING
If you do it twice, automate it. Eliminate manual toil and let humans focus on creative problem-solving.
MONITOR & OBSERVE
You can't fix what you can't see. Build observability into everything from day one.
INFRASTRUCTURE AS CODE
Treat infrastructure like software. Version control, code review, and test everything.
Reliable systems come from clear ownership, ruthless automation, fast feedback loops and empathetic collaboration. I focus on reducing toil, surfacing signal early and making shipping safer & faster.
