Comparing State Machine and Dataflow Pipeline Architectures for Solo Devs
Why Architecture Choices Matter for Solo DevelopersAs a solo developer, every architectural decision carries outsized weight. You have no team to share debugging duties, no code review to catch design flaws early, and no dedicated ops person to untangle deployment snags. Choosing between state machines and dataflow pipelines isn't just an academic exercise—it directly impacts how quickly you can ship, how easily you can fix bugs, and whether your codebase remains manageable as features accumulate. This guide aims to cut through the hype and give you a practical framework for deciding which pattern fits your next project.Many solo devs start with a simple script that grows organically. Over time, that script becomes a tangle of conditionals, flags, and callbacks. At some point, you realize the logic is hard to follow, brittle to change, and nearly impossible to test. That's when you start looking for structure. State machines and dataflow pipelines
