Embracing the 3-Month Rule: A Pragmatic Approach to Non-Scalable Coding
In the tech world, few pieces of advice resonate as deeply as Paul Graham╬ô├ç├ûs call to “do things that don’t scale.” However, while the sentiment is widely acknowledged, the methods of applying this philosophy, especially in coding, are less frequently discussed. Over the past eight months, while developing my AI podcast platform, I have crafted a personal framework that I like to call the “3-Month Rule.” This approach allows each unscalable solution a three-month trial period; after that, it either proves its value and receives the attention it deserves, or it is discarded.
The Dilemma of Startup Engineering
As engineers, we often fall into the trap of creating solutions designed for scalability right from the outset. With concepts like design patterns, microservices, and distributed systems, itΓÇÖs easy to get caught up in creating intricate architectures fit for massive user bases. However, this mindset can lead to wasted resources and excessive complexity, particularly in a startup environment where the focus should be on establishing a foundational understanding of user needs.
My 3-month approach compels me to produce straightforward, albeit “imperfect,” code that can be deployed swiftly. By doing so, I gain invaluable insights into what users genuinely require, rather than what I assume they need.
My Current Infrastructure Experiments: Simple Yet Effective
1. Consolidated Operations on a Single VM
I currently run everythingΓÇöfrom the database to the web serverΓÇöon a single $40/month virtual machine. While this setup lacks redundancy and relies on manual backups, it has provided me with real data about my resource needs more quickly than any capacity planning document could. IΓÇÖve discovered that my platform requires only about 4GB of RAM at peak times, revealing that a complex Kubernetes configuration would have been more hassle than benefit.
2. Hardcoded Configurations
My configuration settings are hardcoded directly into my codebase. For example:
python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
This approach might seem primitive, but it allows quick access to values and ensures that changes are easily tracked through version control. By minimizing the complexity of managing configurations, I save a significant amount of engineering time while still effectively implementing necessary updates.
3. Utilizing SQLite

Thank you for sharing your thoughtful approach╬ô├ç├╢it’s a compelling reminder that sometimes simplicity and speed trump elaborate architectures, especially in the early stages of a project. The 3-Month Rule resonates strongly because it champions rapid validation and learning, which are often overshadowed by the pursuit of scalability from day one.
Your use of a single VM, hardcoded configurations, and SQLite exemplifies a “start simple and learn” methodology that many successful startups have employed to iterate quickly without getting bogged down by over-engineering. This approach not only accelerates development but also provides clear, real-world data to inform future decisions about scaling and infrastructure.
One insight IΓÇÖd add is the importance of consciously assessing when itΓÇÖs time to evolve beyond these initial solutions. Your framework naturally encourages periodic reflectionΓÇöat three monthsΓÇöto evaluate whether the current setup still meets your goals or if a transition to more scalable solutions is warranted. This deliberate timing helps prevent the trap of perpetual under-investment in the right infrastructure, while still maintaining agility.
Overall, this pragmatic approach offers a valuable blueprint for startups and solo developers balancing speed, learning, and resource constraints. Looking forward to seeing how your framework adapts as your platform grows!
This post elegantly captures the essence of pragmatic engineering╬ô├ç├╢prioritizing speed, learning, and iteration over premature scalability. The “3-Month Rule” reminds me of the lean startup philosophy, where validated learning through rapid experimentation takes precedence over elaborate infrastructure from day one.
Your approach of deploying simple, unscalable solutions╬ô├ç├╢like consolidating operations on a single VM and hardcoding configurations╬ô├ç├╢aligns well with the idea of building a “minimum viable” product, enabling real user feedback and data-driven decisions. It╬ô├ç├ûs reminiscent of the “divide and conquer” principle in software engineering: start small, learn fast, and only optimize as you understand actual needs.
This methodology also emphasizes the importance of mindset: engineering is as much about problem-solving as it is about managing complexity. By intentionally choosing not to over-engineer upfront, you create space for genuine insights and avoid sunk costs.
Would be interesting to see how this approach scales as the product maturesΓÇöperhaps integrating automation gradually as needs evolveΓÇöyet maintaining the core philosophy of valuing practical experimentation over theoretical perfection. Thanks for sharing this inspiring perspective!
