AI Systems
That Actually Work
In Production.
We build self-healing n8n automation pipelines and LangGraph AI agents for fast-growing global SMBs. Engineered with retry idempotency, dead-letter queues, and zero ongoing vendor lock-in.
Most "Automations" Are Just
Outsourced Technical Debt.
If your automated pipeline breaks when an API sneezes, you don't have an automation. You have an unmonitored liability.
The Escalating 'Zapier Tax'
Every new lead or webhook execution increases your monthly SaaS bill. You are paying a recurring penalty just for your business growing.
The 2:00 AM Silent Failure
An upstream API changed a field name from 'customer_id' to 'clientId'. The workflow died silently. You lost 40 inbound qualified leads before anyone noticed.
The Disappearing Freelancer
They wired 50 nodes together, got paid, and left. Now nobody on your engineering team dares to touch it because changing one variable breaks everything.
The Unreliable AI 'Toy'
Generic AI chatbots with no state persistence or schema enforcement that send broken replies to VIP clients and corrupt your Postgres records.
Engineered for Uptime.
Priced for Predictability.
No hourly bill shock. All projects delivered on fixed-scope milestone agreements with clean Git repositories and documented handover.
Zapier / Make → Self-Hosted n8n Migration
Stop paying $500–$2,000/mo in recurring automation task taxes. Own your pipeline forever with zero execution limits.
LangGraph Production AI Agents & RAG Pipelines
Deploy deterministic, multi-agent AI systems that handle complex lead qualification, customer intake, and document workflows without hallucination.
Fractional AI Operations & SLA Retainer
Dedicated engineering capacity to maintain, monitor, and continuously enhance your AI automations with guaranteed incident SLA.

Not Just Fancy Slideware.
We operate our own production clusters. Inspect our live n8n workflow architecture or explore our multi-agent runtime blueprints.
Enterprise Multi-Channel Router & Approval Matrix
Production-grade webhook router handling multi-tenant JSON payloads, Redis message debounce buffering, and automatic database failover.
Specialist in Python (FastAPI/LangGraph), TypeScript (Next.js/NestJS), and distributed workflow topologies.
Every workflow is engineered with automated health checks, Dead-Letter fallback queues, and complete architecture documentation.
Flexible scheduling for kickoff calls, daily sprint updates, and guaranteed 4-hour incident response SLA during active retainers.

| CAPABILITY / SPEC | TYPICAL FREELANCER | LEGACY AGENCY | ★ PETHALVOID |
|---|---|---|---|
| Architecture Reliability | Basic node connections. Fails silently on API schema changes. | Over-engineered 6-month enterprise roadmap. | ✓Idempotent, self-healing n8n & LangGraph pipelines with retry layers. |
| Data Ownership & Lock-in | Uses proprietary Zapier/Make accounts. You pay monthly SaaS tax. | Custom blackbox software keeping you locked into their retainer. | ✓100% self-hosted on your own cloud. Full Git repository & zero lock-in. |
| Error Handling & Fallbacks | None. When an error occurs, the workflow silently stops. | Ticket system with 48-hour response time. | ✓Dead-Letter Queue with auto-retry + instant Telegram/Slack alert. |
| Documentation & Handover | Leaves zero docs. Disappears after invoice is paid. | 100-page PDF manual that nobody reads. | ✓Interactive architecture diagrams, video walkthroughs & typed configs. |
| Pricing Model | Hourly billing with no clear finish line. | $10,000–$25,000 upfront setup fees. | ✓Transparent fixed-scope milestones ($800–$2,500) or predictable retainers. |
| Communication & Velocity | Unreliable updates and slow async turnaround. | 3 layers of account managers before reaching an engineer. | ✓Direct collaboration with lead systems architect. Clear async video walkthroughs. |
How We Take You From Chaos
To 99.9% Uptime in 14 Days.
A battle-tested 4-step engineering sprint designed to deliver maximum operational velocity with zero disruption to your daily business.
30-MIN BOTTLENECK AUDIT
We hop on a focused strategy call to map your current automation stack, identify recurring API failure points, and calculate your exact Zapier/task savings.
ARCHITECTURE BLUEPRINT
We produce the complete technical specification: schema definitions, webhook fallback logic, database topology, and a fixed-price milestone contract.
RAPID BUILD & STRESS-TESTING
We engineer the workflows in isolated staging environments. We simulate malformed payloads, rate limits, and network timeouts to ensure 100% idempotency.
ZERO-DOWNTIME HANDOVER
We cut over your production DNS/webhooks seamlessly, configure automated backups & Telegram/Slack monitoring, and transfer all Git repositories & credentials.
