How we pick a tech stack at Matainja

We get asked this question a lot. A founder shows up with an idea and asks: "should we build this in React Native or Flutter? Node or Go? Should we use Next.js or just stick with Laravel?"

Most agencies answer based on what they happen to know best. That's a bad way to answer.

Here's the framework we actually use.

Start from the constraints, not the cool factor

Every project has three hard constraints: time, budget, and the team that will inherit it. Pick whichever stack respects all three.

A founder with $30K and 8 weeks to ship an MVP doesn't need Kubernetes. They need PHP and a $5 VPS. A Fortune 500 with five teams collaborating on a platform absolutely does need that infrastructure investment.

The stack should match the stakes.

The "boring tech" rule

Choose boring technology. The mental energy you save not learning new tools, you spend solving actual problems.

We default to mature, stable, well-documented tools. Postgres over the latest NoSQL of the week. Node over Bun in production. Next.js over the framework that launched last Tuesday.

Boring tech ships. Exciting tech debugs.

When new tech actually wins

That said, here are the cases where reaching for newer tooling is the right call:

• The problem genuinely doesn't have a mature solution — e.g., real-time multiplayer is meaningfully easier with newer WebRTC frameworks.
• The team already knows it well — if your engineers wrote production Rust before, by all means use Rust.
• The product's USP depends on it — sub-100ms response time isn't optional? Go or Rust earns its place over Node.

A worked example

A client came to us last year wanting to build a Trello-style kanban board. Their first ask: "let's use the newest reactive framework." Our recommendation: React + Node + Postgres.

Why? Because every engineer on Earth can debug it. Because their team would inherit it. Because the kanban problem is solved — we didn't need exotic tools.

Six months later, they hired three engineers. Onboarding took a day each. That's the dividend.

TL;DR

1. Constraints first, technology second.
2. Default to boring.
3. Earn the right to use new tools — don't grab them because they trend.

That's it. There's no secret. Just discipline.
