The best tech stack is the one your team can ship with confidently. Everything else is secondary.
Don’t over-engineer early
Microservices sound great until you’re a team of three trying to debug distributed transactions. Start with a monolith; split when you have good reasons.
Pick boring technology
Battle-tested tools have large communities, good documentation, and known failure modes. Save the bleeding edge for genuine competitive advantages.
Optimise for developer velocity
In the early days, the ability to ship fast and change direction matters more than raw performance. Choose tools that let your team move quickly.
