Part 4: Technology Stack Selection

We live in a time of abundance. There are so many free, open-source, and battle-tested tools that can be used to build large-scale projects. But with great choice comes great responsibility.

When I’m working on a personal project, like a quick experiment or prototype, I usually default to the LAMP stack (Linux, Apache, MySQL, PHP). It’s familiar, it’s fast, and it lets me test an idea without overthinking the architecture. If I need to switch from MySQL to SQLite halfway through, or ditch Apache for Nginx, no one’s stopping me.

But when you’re building something like FamFlix, a Netflix-like platform for families to share private videos, the stakes are higher. You’re not just choosing tools for yourself. You’re choosing tools for a team. And that means prioritizing:

• Familiarity: Can everyone on the team work with this tool?
• Scalability: Will this tool handle 10,000 users? 100,000?
• Collaboration: Can we work in parallel without stepping on each other’s toes?

In this article, we’ll explore how to select a technology stack that balances these priorities. And why “just use what you know” isn’t always the best answer.

The Personal Project Mindset: Speed Over Stability

In personal projects, you’re free to:
- Use niche tools: Want to build your API in Rust? Go for it.
- Ignore scalability: If your server crashes, just restart it.
- Skip documentation: You’re the only one who needs to understand the code.

This freedom is liberating, but it comes at a cost. Without a plan, you might:
- Waste time learning a tool that doesn’t scale.
- Hit a technical wall and have to start over.
- Build something no one else can maintain.

For example, I built Shotsrv, my web screenshot tool, using LAMP. I didn’t think about scalability until I hit several hundred jobs running concurrently. Suddenly, my single Apache server was struggling, and I had to rewrite the entire backend to use Node.js and Redis.

The Team Project Reality: Collaboration Over Preference

In a team project, you don’t have the luxury of experimenting with niche tools. You need to:
1. Choose familiar tools: Minimize the learning curve for new team members.
2. Prioritize scalability: Ensure the stack can grow with your user base.
3. Plan for maintenance: Avoid tools that are hard to debug or hire for.

For FamFlix, this means:

• Frontend: React.js (even if I’m not a fan) because it’s widely used, well-documented, and easy to onboard new developers.
• Backend: Node.js with Express.js for APIs, because it’s lightweight, scalable, and integrates well with React.
• Database: PostgreSQL for structured data (e.g., user profiles, video metadata) and Redis for caching.
• Infrastructure: AWS (S3 for storage, Lambda for serverless functions, CloudFront for CDN) because it’s reliable and scalable.

This stack balances familiarity, scalability, and collaboration, while leaving room for future enhancements.

The Cautionary Tale of Microsoft Silverlight

Tool selection isn’t just a technical decision. It’s a business decision. And getting it wrong can have catastrophic consequences.

I once dealt with a company that bet everything on Microsoft Silverlight, a Flash competitor that never gained traction. The project manager had fallen in love with the technology and made it the de facto platform for all their applications. But here’s the problem: most users couldn’t even run Silverlight on their devices.

When the original development team left, the company struggled to find developers with Silverlight experience. They eventually paid a premium to rewrite everything in HTML and JavaScript. A costly lesson in the dangers of untested technologies.

For FamFlix, we’ll avoid shiny new tools in favor of battle-tested ones. As I always say: “I don’t mind working with old, broken tools—as long as I know how they’re broken.”

How to Measure Success in Tool Selection

How do we know when we’ve chosen the right tools? By measuring:

1. Team Onboarding Time:
   • Can new developers contribute within a week?
   • Are there enough tutorials, documentation, and community support?
2. Performance Benchmarks:
   • Does the stack meet our SLAs (e.g., <500ms API response time)?
   • Can it handle 10,000 concurrent users during load testing?
3. Maintenance Costs:
   • Are there enough developers with experience in this stack?
   • Are debugging and monitoring tools readily available?
4. Scalability:
   • Can the stack handle future growth (e.g., 100,000 users)?
   • Are there clear upgrade paths (e.g., from single-server to microservices)?

When the stack meets these criteria, we know we’ve made the right choice.

Why This Process Matters

At first glance, tool selection might feel like a technical detail. But it’s the foundation of your project. By choosing the right tools, we:

• Reduce onboarding time: New developers can hit the ground running.
• Ensure scalability: The stack grows with your user base.
• Minimize risk: Battle-tested tools are less likely to fail.

For example, if we’d chosen a niche frontend framework for FamFlix, we might’ve struggled to find developers. Or worse, hit a wall when the framework lost community support. Instead, we’re building on a stack that’s reliable, scalable, and easy to maintain.

In the meantime, ask yourself:
If I built FamFlix alone, what tools would I choose? And how would that hurt the team?
