If your AI vendor has never shown you a fallback plan,
you don't know what breaks first.

Most AI deployments look fine until the volume doubles or the vendor updates their model. By then, the failure modes are already baked in. The 30-minute audit is free. One workflow. One honest read on what actually holds.

What I’ve shipped.

// Selected work, real outcomes

A few results that say more than a pitch. Built, deployed, and measured.

// SEO engineering

Ranked a client #1 on Google

Built a custom SEO engine that took a client’s pages to the number one organic result on Google.

// Content automation

200+ articles / month, automated

Engineered the pipeline that automatically distributes more than 200 articles per month for a single company, hands-off.

// Crawl & indexing

50,000+ search bots / month

Boosted a site’s crawl to more than 50,000 Google and search-engine bot visits per month, the prerequisite for getting indexed and found.

// Outreach automation

AI SMS engine, 1,200 / hour

Built and deployed a production SMS outreach system with AI-generated messaging that sends 1,200 texts per hour, running on a $50/month plan.

// Browser automation

AI that operates real web apps

Built a phantom-style automation framework that lets an AI drive live browser sessions through genuine clicks and typing, human-like and session-persistent, so it runs unattended where brittle scripts get blocked.

// RAG & content infra

RAG that grounds ChatGPT and Claude

Built an advanced RAG system plus a machine-readable llms.txt layer, so ChatGPT and Claude fetch a site’s own knowledge and generate accurate, on-brand content instead of guessing.

// Private knowledge engine

A private, verified source of truth

Built a local-model RAG system that extracts a company’s data, distills it into procedures, and trains a self-hosted model on them, with a QA agent verifying every step. The result is one private, accurate source of truth that never leaves the company’s infrastructure.

// Cost engineering

70 to 80% lower AI bills, quality held

Built a multi-layer system that runs most work on local models on the company’s own hardware and routes only the hard calls to Claude, Codex, or the cheapest capable cloud model. The AI bill drops 70 to 80%, the data stays private, and quality stays maxed.

The vendor is not the risk. The assumption is.

// Free reports, no email-wall

Most teams evaluate AI vendors with three signals: demo quality, review aggregators, and a reference call. None of those surface the failure modes that appear in production. These four reports cover what a technical review actually requires. Each is 13 to 16 pages, primary-source. Pick the one that maps to your decision.

This is not an AI capability problem. It is a production readiness problem.

// The honest read

A no-code agency is fast and cost-effective, and genuinely good at workflow automation. They optimize for delivery speed, not for the error budgets and fallback paths that hold up under volume.

The vendor's own implementation team knows the platform and can configure it in days. Their incentive is adoption. The handover happens on their timeline, not yours.

Building internally works if the team has shipped production systems before. The gap is that AI failure modes don't surface like traditional software bugs. A silent hallucination doesn't trigger a 500 error. The published term for this class is specification aliasing: an underspecified prompt causes the model to fill missing information bands with hedging, hallucination, and structural incoherence. No exception raised, no stack trace. ↗ first-party research

The reason most AI deployments degrade under load is the same reason electrical installations fail: the team built for the expected case, not the failure case. Seven years of electrical engineering in Luanda before a line of Python. Buildings go dark when a fault path is missed. That discipline is what production AI requires: monitoring on every critical path, error budgets, fallback paths, drift detection, and runbooks the operator can read at 3 AM.

You own the code. Full handover, no platform lock-in, no proprietary dashboard you can't access without my login. If we part ways tomorrow, you keep operating.

Author's own production system: specification engineering reduced effective API cost from ~$1,500/month to ~$45/month (97% reduction). First-party result, single system, not peer-reviewed. CC BY 4.0. Mario Alexandre, March 2026.

“A 16-phase orchestrator with explicit JSON state, checkpoint recovery, and clean interfaces between phases. Knowing he had already put the pattern through 61 production runs gave us confidence.”

David Chen, CTO, developer-tools startup · Vancouver

“A 6-stage lead discovery and scoring pipeline that fit our intake process and produced 24 qualified leads we could action immediately. Every lead came with the same fields and a score.”

Sofia Morales, Agency Owner, content & demand-gen agency · Mexico City

“Ray with async I/O, retries, idempotent state. The design is explicitly sized for a 500K-item target with backpressure and checkpoints instead of silent drops.”

// Let's Build Something That Works

Find out before it matters.

A 30-minute audit starts with one workflow. I map what it assumes, flag the failure modes, and give an honest read on whether the vendor relationship, the build approach, or the monitoring posture needs to change. If I'm not the right fit, I'll say so.
