The 3-Month Rule: A Practical Approach to Non-Scalable Solutions in Development

In the realm of entrepreneurship, particularly in tech startups, the mantra “Do things that don’t scale” is often echoed by luminaries like Paul Graham. However, translating this philosophy into practical coding strategies remains less frequently discussed. After spending eight months developing my AI podcast platform, I’ve crafted a straightforward framework that can be easily adopted: every unscalable hack is given a lifespan of three months. At the end of this period, it either validates its worth, leading to a robust implementation, or it gets phased out.

The startup Dilemma: Why Scalable Solutions Can Be Misleading

As developers, we are often conditioned to focus on scalable solutions right from the outset—envisioning intricate design patterns, microservices, and systems capable of accommodating millions of users. While such architectural beauty has its place, it’s typically associated with larger organizations. In the ecosystem of startups, chasing scalability can transform into an expensive form of procrastination, addressing future user issues that may never materialize. My three-month rule compels me to prioritize direct, albeit imperfect code that can be shipped quickly, providing valuable insights into real user requirements.

Innovative Infrastructure Hacks That Make Sense

Here are the unscalable tactics I’m employing and the intelligent rationale behind each one:

1. Unified Virtual Machine (VM) Strategy

I operate my database, web server, background jobs, and Redis on a single virtual machine costing $40 per month. While this may seem unwise for redundancy, it has revealed my actual resource needs more efficiently than any planned capacity document. I discovered that my resource consumption peaks at a mere 4GB of RAM. Instead of wrestling with a complex Kubernetes setup that would likely manage idle containers, I gain critical insights every time my system crashes—offering data about unexpected failures.

2. Hardcoded Configurations

My application is filled with hardcoded constants such as pricing tiers and user limits. While this approach may appear outdated, it grants me the ability to quickly search through my codebase for configuration values and maintain a clear historical record of changes. Reducing the engineering effort of creating a configuration service, which could take up to a week, to a mere 15 minutes of redeployment has proven far more effective for the few adjustments I’ve required.

3. Utilizing SQLite in a Multi-User Environment

I’ve opted to use SQLite for my multi
