Sihilel Himasara's Corner of the Internet.
Welcome to the place where I document my journey — the solutions, the struggles, and everything in between.
About Sihilel
“Never let an opportunity go away.”
Since childhood, I have always wanted to understand how things work under the hood. In 7th grade, I stumbled upon a YouTube programming tutorial — that was the exact moment I wrote my first lines of code. Since then, I’ve learned step by step, realizing early on that I learn best by experimenting and breaking things on my own rather than merely following tutorials.
I have been freelancing since 2020, starting with simple website design and progressively expanding into full-stack engineering, systems, and interactive graphics. In early 2025 following my A/Ls, I joined Softsora as a Software Engineering Intern. Following a successful one-year internship, I stepped up as an Associate Software Engineer.
