Yazky
Saputra
yzlabs is my personal lab — where I learn, break things, and build them better. A space for experiments, side projects, and honest documentation of the process.
About
I treat coding like a playground, not just a profession.
I'm Yazky — a developer who builds things at the intersection of curiosity and code. yzlabs is my corner of the internet where experiments happen without permission slips: from full-stack apps to random prototypes that keep me up at night.
I build in public, share what I learn, and believe the best way to grow is to ship often and fail honestly. Most of what I know comes from breaking things and then figuring out why they broke.
When I'm not coding, I'm probably making content about coding — because teaching is the fastest way to understand something deeply.
What I Do
A few things I spend my time on
Full-Stack Development
End-to-end web applications. From database schema to pixel-perfect UI — I build things that work for real people, not just demos that look good in a portfolio.
Product Prototyping
Rapid prototyping to validate ideas fast. I turn rough concepts into working prototypes before the first meeting ends — because talking about an idea and clicking through it are completely different things.
Experimentation
yzlabs is my sandbox. I explore new tools, frameworks, and patterns — not because a client asked for it, but because I want to understand how things work under the hood. Most experiments don't see the light of day. Some become projects.
Content & Community
I document my process on social media. Building in public isn't just a strategy — it's how I stay accountable, connect with people who build too, and remind myself that progress doesn't need to be perfect to be worth sharing.
Projects
Things I've shipped
A selection from the lab
Cronicle
A minimal time-tracking app built for developers who hate time-tracking. Keyboard-first, zero friction, no BS.
Vaultbox
An open-source password manager with a local-first approach. No cloud dependency, no trust issues. Your keys, your machine.
Devlog
A CLI tool that generates clean changelogs from git commits. Because nobody wants to write them manually, and automation fixes everything.
Pulse
Real-time collaboration engine prototype. WebSocket-based, built to understand what makes tools like Figma feel instant.
