We solve the engineering problems that keep good products from scaling.
ProxyPattern is a boutique software architecture and AI engineering firm. We design simple systems, eliminate moving parts, and scale backend infrastructure for ambitious software teams.
"We believe software should become easier to change as it grows—not harder. We help ambitious teams build systems that scale in complexity as slowly as possible."

What We Fix
Founders don't hire us for generic development. They hire us when their infrastructure is buckling or velocity has stopped.
"Our product is slowing down under load."
Most database performance bottlenecks aren't PostgreSQL limitations—they are caused by long-running transactions holding locks, un-indexed tables, and N+1 queries. We audit lock times, clean up schemas, and implement chronological table partitioning to drop database load.
Explore Database Audits →"AI features are becoming slow and expensive."
Direct model calls introduce massive network latency and run up thousands in billing costs. We decouple your LLM pipeline, introduce semantic Redis caches to serve recurring requests instantly, and set up programmatic grading suites in CI to prevent regression.
Explore AI Orchestration →"Our developers can't ship code quickly anymore."
Velocity decreases because of speculative abstractions, bloated dependencies, and slow local test suites. We audit dependency trees, prune unused library files, mock external API targets to speed up test execution, and implement clear, asynchronous design specifications.
Explore Codebase Refactoring →How We Make Decisions
Good consultancies sell expertise. Great consultancies sell judgment. Here is our stance on building software.
We prefer removing complexity over managing it.
Every line of code, package, or server instance is liability and overhead. The most reliable code is the code you didn't have to write. We focus on deleting dead paths and streamlining flows.
We choose boring technology whenever possible.
Stable, mature databases and monolith frameworks (PostgreSQL, Rails, Redis) utilized to their full capability solve 99% of business challenges with a fraction of the maintenance cost of microservices.
Every dependency must justify its existence.
Pulling in a massive external package to bypass writing 15 lines of code is a bad trade. We audit dependencies to protect your application from security vulnerabilities and compilation drag.
Scaling a live Conversational AI pipeline.
A growing customer support platform was spending thousands of dollars on direct GPT-4 API calls. Sluggish response times (latency) were causing customer churn, and database lockups blocked operations.
Instead of rewriting the application, we decoupled the architecture. We implemented semantic Redis caching to serve repeated queries instantly, offloaded audit persistence to Sidekiq, and optimized the streaming connections.

Founder & Principal Engineer"Over a decade designing Rails systems, AI platforms, and high-scale web applications."
I founded ProxyPattern to provide high-execution, senior-level architectural and scaling partner services directly to ambitious software teams. No layers of account managers, no junior developers training on your budget. Just direct engineering results.
Core Engineering Principles
We have a recognizable engineering philosophy. We build software that compounds in value over time.
Complexity is debt with interest.
Every line of code, dependency, or server configuration is a liability. We design to remove moving parts.
Determinism before AI.
Large Language Models are probabilistic engines. Before adding an AI model, ask if a database query or regex can solve it.
Prefer boring technology.
We build systems using stable, mature stacks (Rails, Next.js, PostgreSQL, Redis). We focus on maximizing their native capabilities.
Our Compounding Journey
ProxyPattern isn't a static brochure. We are building a long-term engineering institution to research and ship deterministic software.
Consultancy
Senior software architecture and scaling audits.
Research & Playbooks
Asynchronous guidelines and prompt evaluation frameworks.
Open Source
Public packages and utilities to validate dependencies.
Architecture Audits
Productized codebase deep-dives and custom scanners.
Products
Developer productivity tools and deterministic platforms.
We teach what we build.
We share our engineering approaches, open-source libraries, and complexity guides. You can audit how we solve problems before scheduling a call.
The Playbook
Read our exact frameworks: how we programmatically evaluate AI systems, find PostgreSQL queries holding locks, and decide when NOT to use AI.
Open the PlaybookOpen Source
Audit our public codebases. We build public utilities like GemGuard to track lockfile packages and validate dependencies in CI.
