The Principles We Engineer By
We believe that software should become easier to change as it grows—not harder. Here is the operational philosophy behind every system we design and line of code we write.
Complexity is debt with interest.
Every line of code, dependency, or server configuration is a liability. We design to remove moving parts. Simple code is cheaper to write, easier to debug, and faster to scale.
When a codebase grows, developers often add abstractions to handle speculative future requirements. We do the opposite. We prune unnecessary abstractions, clean up dependency charts, and favor straightforward code over clever, heavily-metaprogrammed logic.
// Over-engineered abstraction to handle hypothetical databases
class DatabaseProxyFactory {
constructor(provider) { this.provider = provider; }
async execute(query) { return this.provider.query(query); }
}
// Simple, direct approach: just query the database connection
const result = await db.query("SELECT * FROM users WHERE id = $1", [id]);Determinism before AI.
Large Language Models are probabilistic engines. Before adding an AI model to your stack, ask if a database query, state machine, or simple regex can solve it. Keep your system deterministic where possible.
AI is a powerful tool, but it is expensive, slow, and non-deterministic. We follow a strict 'problem solving ladder.' If a task can be resolved with standard algorithms, SQL queries, or regular expressions, we implement those first. We only spend tokens when human-like reasoning is genuinely required.
// Probabilistic classification (expensive, slow, inconsistent)
const category = await llm.classify(ticketText);
// Deterministic alternative (95% speed increase, 0 cost, 100% consistent)
const category = ticketText.match(/billing|invoice|payment/i) ? 'billing' : 'support';Prefer boring technology.
We build systems using stable, mature stacks (Rails, Next.js, PostgreSQL, Redis). We focus on maximizing their native capabilities rather than constantly introducing new libraries.
Stable technologies are predictable, well-documented, and performant. Instead of adding a dedicated vector database, we utilize Postgres pgvector. Instead of setting up a complex microservice fleet, we maximize the capacity of a modular monolith. Boredom in infrastructure leads to excitement in product delivery.
# Adding pgvector to a PostgreSQL migration (no new infrastructure needed)
class AddVectorExtensionToDatabase < ActiveRecord::Migration[7.1]
def change
enable_extension "vector"
end
endSimplicity scales.
Scaling isn't about rewriting your app in Rust; it's about database indexing, caching strategies, efficient queue processing, and removing N+1 queries.
Startups often assume that scaling issues are caused by their programming language or framework. In 95% of database audits, the performance issues are solved by setting up the correct indexes, partitioning chronological tables, and removing N+1 queries. Monoliths scale incredibly well when built properly.
# N+1 Query: loads users and triggers database queries for each profile
users = User.limit(10)
users.each { |u| puts u.profile.bio } # 11 database queries!
# Optimized: loads all profiles in a single query
users = User.includes(:profile).limit(10)
users.each { |u| puts u.profile.bio } # 2 database queries!Architecture is leverage.
Good system design compounds. When your database schema matches your business domain, feature velocity stays fast. When it doesn't, engineering speed grinds to a halt.
A clean architecture pays dividends every time a developer opens a editor. When code has clear boundaries and dependencies are unidirectional, refactoring is trivial and risk of regressions is minimized. We focus on building clean core domains first.
// Tangled coupling: database operations inside frontend layouts
function UserProfile({ userId }) {
const user = db.query("SELECT * FROM users..."); // Direct database call in UI!
}
// Clean architecture: decoupled layers
async function getUserProfile(userId) {
return db.query("SELECT * FROM users..."); // Persistance layer
}
function UserProfile({ user }) {
return <div>{user.name}</div>; // Pure UI layout
