From 1s & 0s to Vibe Hardening.
I'm Yassir, a software developer and builder. I started coding in 2018, and in 2021 I founded WebMastry, a development agency delivering production software for founders worldwide.
I've been working with non-technical founders since 2021. I've seen the full development cycle—from idea to design to MVP. I've watched founders get blocked by not being able to write their own code, needing us for every small change, intimidated by the very codebase they paid tens of thousands to build.
Today, this changes. AI tools like Claude and Cursor grant founders unprecedented visibility. They can see, edit, and even create new code and features. All they need is a little hand-holding to do it right—and that's where I come in.
AI is changing everything.
But speed without structure is a trap.
Today, I see a gap. Founders are building faster than ever with AI, but they're missing the "hardened" engineering foundation needed to truly scale. I'm here to fix that.
Vibe Coding is Real
AI tools let you build MVPs in days. The velocity is intoxicating—and dangerous if you don't know what you're shipping.
The Gap Emerges
Non-technical founders can build, but they can't diagnose production failures, security holes, or scaling bottlenecks.
Hardening is the Answer
I bridge the gap—turning AI-generated prototypes into production-ready systems that won't crumble under real users.
My Journey
The Beginning
Started coding journey with data analysis using R and Python.
Web Development Era
Dove into web development. Built first few client projects, learning the ropes of full-stack development.
WebMastry Founded
Got serious. Founded WebMastry and started delivering production software for startups across US, Australia, New Zealand, Germany, and beyond.
Scaling Projects
Delivered dozens of projects: full-fledged products, MVPs, small implementations. Served thousands of users. Projects ranging from $5k to $100k+.
Vibe Coding Era
Discovered AI coding tools and started helping "vibe coders". Now running one-on-one coaching program guiding founders through their AI-assisted builds.
