Fullstack Developer & Infrastructure Engineer
Hi, I'm Deni Hidayat.
I build web and mobile applications — from the first line of code to a secure, stable production server.
About
One whole job
I'm a developer who enjoys solving problems end to end. Writing the backend and frontend, designing the database, then making sure everything is deployed cleanly, securely, and stays up when traffic arrives — to me that's one whole job, not three separate ones.
I'm used to working calmly under pressure: handling production incidents, meeting tight deadlines, and making clear technical decisions when time is short. What I keep constant is honest communication and dependable results.
If you're looking for someone you can trust with an application from code to server, there's a good chance we'll work well together.
Skills
Three things I do
Fullstack development, servers & infrastructure, and application security — the combination of all three is what lets me carry an application from an empty repository to running in production.

How I work
How I work
Four things you can expect from me, on any project.
-
Clear communication
Good news or bad, you hear it from me early — not at the last minute.
-
Calm under pressure
I meet production incidents and tight deadlines with measured steps, not panic.
-
Ownership, end to end
Done means running in production — secure, monitored, and documented.
-
Secure by default
I think about security at design time, not after something breaks.
