Embracing the Unscalable: A Three-Month Framework for Rapid Learning in Tech Development

In the world of tech startups, it’s common to hear the advice from Paul Graham: “Do things that don’t scale.” Yet, the challenge remains: how do you apply this concept in practical coding scenarios? After eight months of developing my AI podcast platform, I’ve crafted a straightforward approach to this dilemma: every unscalable solution I implement gets a lifespan of just three months. At the end of this period, it either demonstrates its worth and is refined into a robust system, or it is phased out.

As engineers, we often focus on building scalable solutions from the outset: employing design patterns, microservices, and distributed systems that are capable of handling millions of users. However, this approach can be more appropriate for established companies than for startups, where investing in scalable infrastructure can lead to significant delays and unnecessary complexity.

The Three-Month Rule: A Practical Approach

My three-month rule encourages me to prioritize straightforward and functional code that’s ready for deployment, allowing me to better understand user requirements. Here are some of my current infrastructure hacks and the rationale behind them:

1. Consolidated Operations on a Single VM

Currently, my entire stack—database, web server, background jobs, and caching—runs on a single virtual machine costing $40 per month. This setup lacks redundancy and relies on manual backups to my local system.

Why This Method Is Effective: Within a mere two months, I’ve gained genuine insights into my actual resource requirements. My platform’s peak usage is just 4GB of RAM, negating the need for a complex Kubernetes architecture that I initially considered. When issues arise (as they’ve done twice thus far), I gather valuable data about what truly fails, which often surprises me.

2. Utilization of Hardcoded Configuration

My codebase features hardcoded constants for configurations rather than utilizing config files or environment variables:

python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"

The Benefit: Although this might seem primitive, it simplifies the process of searching and tracking changes. Modifications require only a brief redeployment, saving me countless hours of engineering effort for configurations that I have only adjusted three times in three months.

3. Employing SQLite in Production
