Embracing the 3-Month Rule: A Practical Approach to Development Without Scale
In the tech world, Paul Graham famously advised, “Do things that don’t scale.” However, the challenge often lies in translating this advice into practical coding strategies. After eight months of developing my AI podcast platform, I’ve devised a straightforward framework to navigate the unscalable: every workaround or hack is allotted a mere three months to demonstrate its worth.
As engineers, we are instinctively drawn towards creating scalable solutions right from the onset. We envision ideal architectures with intricate design patterns, microservices, and distributed systemsΓÇötools that are optimal for managing vast user bases. This instinct, however, can lead us astray, especially in a startup setting where scalability often becomes a costly form of procrastination. Instead, I advocate for writing simpler, more direct code that is functional and that genuinely illuminates user needs.
My Current Infrastructure Strategies: Pragmatic Choices that Drive Learning
1. Consolidated Resources on a Single VM
All of my essential services╬ô├ç├╢from the database and web server to background jobs and caching╬ô├ç├╢operate on a single $40/month virtual machine. Yes, there╬ô├ç├ûs no redundancy, and backups are done manually, but this setup has been enlightening. In just two months, I’ve gained better insights into my resource demands than through any sophisticated planning document. My platform, which I had initially categorized as “AI-heavy,” peaks at just 4GB of RAM. The complex Kubernetes infrastructure I once considered would have been managing unused containers.
When the system crashes (which has happened a couple of times), I receive immediate feedback on what truly failsΓÇönot what I assumed would break.
2. Unconventional Configuration Management
Instead of utilizing configuration files or environment variables, IΓÇÖve opted for hardcoded constants like:
python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
While it may seem impractical, this approach reveals its benefits: I can quickly search my codebase for configuration values, and all changes are documented in my Git history. Over three months, IΓÇÖve only modified these constants three times, making the time spent redeploying negligible compared to the hours that could have gone into creating a separate configuration service.
3. Using SQLite in Production
Believe it or not, I am utilizing SQLite for my multi-user web application. My

Thank you for sharing this insightful approach! I love how you’ve embraced the philosophy of “doing things that don╬ô├ç├ût scale” in such a pragmatic way╬ô├ç├╢especially with the 3-month rule as a tangible deadline. It reminds me that early-stage development often benefits from speed and flexibility over perfection, allowing us to learn what truly matters for users before over-engineering.
Your resource consolidation strategy on a single VM exemplifies the value of simple setups for rapid feedback, which is often overlooked in favor of complex architectures. Likewise, choosing hardcoded constants over configuration files may seem unorthodox, but it accelerates iteration and helps clarify what parameters are truly criticalΓÇöthen you can refactor once the product matures.
Regarding SQLite in production, while itΓÇÖs unconventional at scale, in early phases or small user bases, it can be a perfectly valid choiceΓÇösaving time and reducing complexity. ItΓÇÖs about knowing when to optimize or scale up, not rushing into it prematurely. Thanks for encouraging such a balanced, learning-oriented mindsetΓÇöfocusing on real feedback first, then gradually scaling as insights develop.
This post beautifully underscores the value of embracing simplicity and rapid experimentation in the early stages of development. The “3-Month Rule” serves as a pragmatic counterbalance to the often paralyzing pursuit of perfect scalability from day one╬ô├ç├╢a mindset that can hinder learning and agility, especially in startups.
Your approach reminds me of the concept of “working code over perfect architecture,” which encourages developers to prioritize delivering functional solutions that provide immediate insights. Using a single VM for all services, and employing hardcoded configuration constants, are practical strategies for rapid iteration and learning. These tactics echo the principles of the “No Big Upfront Design” philosophy, emphasizing that initial solutions should be flexible and iteratively refined based on real-world use.
Additionally, your choice of SQLite in production highlights an important lesson: for low to moderate scale applications, simpler data stores can be sufficient and reduce overhead. Many successful products start with such lean setups, proving that addressing immediate needs effectively often trumps prematurely optimizing for scale.
Overall, your framework exemplifies a balanced approachΓÇöprioritizing rapid feedback, learning, and adaptability over rigid, costly architectures. This mindset can be invaluable for startups and developers looking to innovate quickly without getting bogged down in unnecessary complexity.
