We eliminate the manual work that's slowing your business down.
ProxyPattern helps growing organizations connect disconnected systems, automate repetitive workflows, and apply AI where it actually improves operations. We find the bottlenecks, design the solution, and build it—without adding unnecessary complexity.

Where Does Your Team Lose Time Every Week?
Founders and operators don't call us for generic developer hours. They call us when manual data entry, broken tool integrations, or operational friction slow down business growth.
“Our team is copying information between systems.”
We connect your CRM, email, spreadsheets, scheduling systems, and internal applications so information moves automatically—without human intervention or transcription errors.
“Staff spends hours on repetitive administrative work.”
We map your recurring administrative tasks, remove the manual steps, and build streamlined digital intake and automated notification pipelines.
“Our business has outgrown its manual processes.”
When spreadsheets and paper forms break down, adding more staff creates overhead. We redesign the workflow architecture so your capacity scales without extra payroll.
“We have AI ideas but don't know what's worth automating.”
We apply our “Determinism before AI” framework: we identify where standard algorithms make more sense—and where AI genuinely adds high-ROI value.
“Follow-ups are getting lost and bookings stall under load.”
Unstructured messaging queues and manual client follow-ups lead to lost revenue. We construct automated scheduling and notification pipelines that never miss a lead.
“Our core software app is slow, fragile, or expensive to run.”
For software companies and tech teams, we fix PostgreSQL row lock contention, refactor legacy monoliths, and optimize cloud infrastructure under peak traffic.
Under the hood, we solve these with system integration, custom APIs, automated queues, AI orchestration, database engineering, and clean software architecture.
Growing Organizations with Complex Operations
We don't limit our work to one narrow vertical. We help organizations whose operational complexity has outgrown manual handling.
Service & Care Organizations
Healthcare clinics, nutritionists, social service agencies, and care providers needing automated patient intake, scheduling, reminders, and client follow-up.
Professional & Financial Services
Lending operations, legal firms, accounting practices, and financial entities seeking to eliminate spreadsheet tracking, document processing, and billing overhead.
Software & Technology Companies
SaaS scale-ups, founders, and VPEs needing senior database tuning (PostgreSQL, Rails, Redis), AI evaluations in CI/CD, and monolith refactoring.
Paper & WhatsApp → Automated Intake & Meal Booking Workflow
Unstructured WhatsApp messages and paper intake forms were causing lost follow-ups and booking bottlenecks for Chef Nutritionist Jennifer Núñez.
We digitized client health evaluations, built multi-step intake questionnaires, and created automated WhatsApp & email workflows that eliminated manual friction.
Unstructured WhatsApp chats, paper health evaluations, lost client follow-ups, and manual scheduling bottlenecks.
Digital health evaluation portal, multi-step automated intake, synchronized booking workflows, and instant client notifications.
Spreadsheet Chaos → Automated Credit Ledger & WhatsApp Collections
Replaced fragile loan spreadsheets with an immutable accounting engine, French amortization schedules, and idempotent WhatsApp payment collection queues.
High Latency AI → 45% Billing Drop & 60% Faster Responses
Decoupled a high-traffic AI support pipeline with semantic Redis caching and async workers to cut model spending while boosting user speed.
“Good consultancies sell labor. Great consultancies sell judgment.”
Hourly billing rewards slow work. We charge for impact and senior judgment instead. You aren't paying for developer hours—you are paying for an experienced architect to analyze your operation, remove unnecessary complexity, and build what actually works.
Pay for concrete operational outcomes and senior engineering judgment—not elapsed hours.
How We Solve Problems
We design simple, reliable software systems that eliminate operational friction without ballooning cost.
We remove complexity first.
Every manual step, extra dependency, or bloated app is maintenance debt. The most reliable solution is the simplest one. We prune dead workflows and simplify operations.
Determinism before AI.
LLMs are probabilistic. Before adding an AI model, we check if SQL, regex, APIs, or a state machine solves the bottleneck deterministically.
We default to boring, proven tools.
PostgreSQL, Rails, Redis, and Next.js handle 99% of organizational workloads cleanly when configured properly—without microservice sprawl.

Founder & Principal Engineer“Over a decade walking into complex operations, identifying bottlenecks, and building clean automated systems.”
I founded ProxyPattern so organizations can work directly with a senior engineer—no account managers, no junior developers learning on your dime. Just clear, direct operational solutions.
Core Engineering Principles
We build software designed to compound in value over time.
Complexity is debt with interest.
Every manual step, extra dependency, or unintegrated tool is an operational liability. We design to remove moving parts.
Determinism before AI.
LLMs are probabilistic. Before adding an AI model, we check if SQL, regex, or a state machine solves the bottleneck deterministically.
Master stable tools.
We build on mature stacks—Rails, Next.js, PostgreSQL, Redis. We push native capabilities to their limits before adding unnecessary software.
