From Product Manager to Founder-Builder: How AI “Vibe Coding” Helped Me Ship in 4 Months What Used to Take Much Longer
In the last 4 months, I went from Product Manager to founder-builder using AI “vibe coding.” I started with ChatGPT copy-paste coding, then moved to IDE workflows with Amazon Q, real stacks, and real cloud. This is how AI removed waiting—and helped me ship faster than ever.
Four months ago, I was operating in a familiar Product Manager reality: I could define a roadmap, write PRDs, align stakeholders, and design flows—but shipping still depended on developer bandwidth.
If you’re a PM or founder, you already know the hidden cost: waiting.
Then AI became practical. Not “cool demo” practical—ship-real-products practical. People started calling this new style vibe coding: building apps by describing what you want in natural language and iterating fast with AI.
This is my story of how that shift changed my workflow, my confidence, and my speed—both for my own ventures and inside my day job.\
1) A Quick Intro
I’m Mohammad Sazzad Hossain—a Product Manager and tech entrepreneur. I’ve spent years leading product delivery across SaaS and cloud-based solutions, focusing on turning complex business problems into simple, usable software.
But no matter how strong your product thinking is, there’s a bottleneck you can’t “strategy” your way out of:
The distance between idea and execution.\
2) Before Vibe Coding: The Typical PM Friction
Before I became a vibe coder, most product cycles looked like this:
- Dependency on engineering bandwidth even for small MVPs
- Communication gaps between product intent and implementation details
- Slow feedback loops (weeks to learn what users think)
- Go-to-market delays because everything stacks: build → fix → deploy → repeat
This isn’t about blaming developers—great engineers are the reason products exist. But the traditional flow has inertia. And when you’re trying to validate fast, inertia is expensive.\
3) How I Started: ChatGPT Copy-Paste Coding (and a First Win)
My first vibe-coding workflow was simple:
- Open ChatGPT
- Describe what I want (features, UI, behavior)
- Copy the code
- Paste into my IDE
- Test → break → fix → repeat
My first serious “I built this” moment was Prompt Buddy, a Chrome extension. That project did something important: it proved to me that I could go beyond mockups and actually ship working software.
Then I hit quota limits.
Instead of stopping, I upgraded my ChatGPT plan—and that decision mattered. It wasn’t about “buying AI.” It was about committing to a new execution speed.\
4) Becoming a Full Vibe Coder: IDE + Agents + Real Stacks + Real Cloud
The big transformation happened when I moved from “chat-window coding” to an AI-assisted development workflow inside my IDE, with real stacks and real infrastructure.
IDE workflow that changed the game
I started using Amazon Q Developer inside VS Code, especially the inline chat workflow: highlight code, give instructions, and get suggested changes as a diff—right inside the editor. That removed the constant context-switching between chat and code.
My builder stack (what I used depending on the project)
- Next.js for modern product websites and full-stack apps (App Router, server components, production-ready structure).
- Supabase when I needed auth + database + fast backend workflows, with Row Level Security (RLS) for data protection.
- Laravel when a structured backend was the right choice
- Vercel / Netlify when I wanted fast deployments and quick preview links (Vercel is especially smooth for Next.js).
Cloud as a speed advantage (AWS + Azure + DigitalOcean)
This is where vibe coding became “founder-grade” for me: I wasn’t just generating code—I was shipping production systems.
- AWS when I needed scalable building blocks and proper deployment pipelines (including AWS Amplify hosting workflows for Next.js).
- Azure when App Service fit the project—especially GitHub Actions deployments that turn pushes into releases.
- DigitalOcean when I wanted clean simplicity—App Platform can deploy directly from Git repos and auto-redeploy on changes.
At this point, I stopped feeling like a PM “trying to code.” I became a founder-builder with a repeatable loop:
Prompt → Build → Test → Deploy → Iterate\
5) What I Built in the Last 4 Months (By Category)
Here’s what I shipped—real products and real websites.

6) The Unexpected Result: I Helped My Company Move Faster Too
The biggest “wow” moment wasn’t just personal projects.
I applied the same vibe-coding workflow at my company—building prototypes, flows, and usable pieces faster than the traditional cycle. Not because AI made me “better than developers,” but because it removed the most expensive delay in product delivery:
waiting for the first working version.
When you can show something real quickly:
- alignment becomes easier
- misunderstandings drop
- risks appear early
- iteration becomes cheap
Management noticed—because outcomes showed up faster.\
Conclusion: The Founder Advantage Isn’t “Coding”—It’s Shipping
Vibe coding didn’t replace product thinking. It multiplied execution.
Today, I still do the core PM work: discovery, prioritization, UX thinking, stakeholder alignment. But now I can also build the MVP, validate quickly, ship improvements fast, and move the product forward without being blocked.
My sharp founder lessons
- Speed is a strategy. Faster loops mean faster truth.
- Working demos reduce miscommunication. Prototypes end debates.
- AI shifts the bottleneck. From “resources” to “clarity.”
- Shipping confidence compounds. Once you ship repeatedly, you stop fearing the next build.
If you’re a PM or founder reading this: you don’t need to “become a developer” to benefit from vibe coding.
