Hello, I'm Degz Arbiz
AI Systems Developer for LLM apps and automation
I build production AI systems, LLM evaluation harnesses, prompt architecture, and business automation.
AI Systems Developer and automation architect. LLM-powered applications, the evaluation harnesses that keep them honest, and the workflow infrastructure that connects them to real business operations. 8+ years across digital systems, SaaS and automation.

Scoped engagements, senior execution, no hand-holding. Everything below is something I've shipped in production.
LLM applications & agent systems
Apps on Claude and other LLM APIs with structured I/O contracts, role-based instruction frameworks, and evaluation passes that hold behaviour steady under real load.

The layer underneath — backend logic, API and webhook integrations, job queues, and modular components wiring AI into CRMs and operational tooling.

Getting a team productive with AI coding agents — workflow design, prompt standards, and live training. I run this weekly for complete beginners.

Sales Coach AI — AI pipeline layer
Apr – Aug 2026
Real-time sales coaching over live calls: a TypeScript monorepo with a Fastify API,
Next.js client using live tab capture, and a BullMQ worker running Claude pipelines
against call audio, backed by Postgres, Redis and R2.
Built by a team of six; I own the AI layer — the coaching pipelines
and prompt architecture in packages/ai — and wrote the cue-evaluation
harness that gates output against a scripted quality bar instead of manual review.

BranDoor — AI brand identity studio
2026 · in developmentAn independent brand identity studio that turns a short business questionnaire into a strategy brief, distinct visual directions and editable vector marks. I built the Next.js product, its staged AI workflow, a library of thirteen sample identities and photographic case studies that show each brand in use. The interactive studio is currently a local prototype; these screenshots show the product and sample work without suggesting a public demo is live.
Scale With System CRM
OngoingBuilt and operate a white-labelled sales and marketing platform for the Philippine market — CRM and pipeline, appointment scheduling, funnel builder, course portal, unified inbox, and local payment integration. Two commercial tiers with live paying customers.

Earlier
Inside sales, technical support, and customer service across enterprise software and BPO — where the systems-and-process instinct came from. Full detail in the résumé.
05 / Stack
Tools I ship with, daily.
06 / Teaching
I teach this, live, every week.
A free live training taking complete beginners from an idea to a working, deployed AI application — turning a concept into requirements an AI can act on, building with AI coding agents, then running, testing and iterating. No programming background required.
07 / Clients
What they said.
They went well beyond the web and funnel work — taking on responsibilities closer to a project manager.
I can now take vacations without any worries.
The consultations were valuable enough that I offered to pay before the project even began.
08 / FAQ
What teams usually ask.
What exactly do you own on a project?
The AI layer end to end: prompt architecture, the pipelines that call the model, the integration points into your APIs and CRM, and the evaluation that proves output quality before it ships. On Sales Coach AI that's packages/ai plus the cue-evaluation harness.
I work well alongside an existing frontend and platform team — I don't need to own the whole stack to be useful.
How do you keep LLM output reliable?
Structured input/output contracts, role-based and constraint-driven instruction frameworks, and a scripted evaluation gate rather than eyeballing results. If output quality drops below the bar, the build fails instead of quietly shipping.
Do you work with non-technical teams?
Routinely. Most of my client work has been translating what a business owner wants into something a system can actually do. I also run a free weekly live training taking complete beginners from an idea to a deployed AI app, so explaining this clearly is a practised skill, not an afterthought.
Your background is automation and BPO, not a CS degree. Why hire you for AI?
Because the hard part of production AI is rarely the model. It's knowing which business process is worth automating, what the failure modes cost, and how to integrate with the messy tools a company already runs. Eight years of doing exactly that — CRM systems, funnels, support operations, SaaS onboarding — is why my AI work ships instead of demoing.
The engineering is real and inspectable: TypeScript monorepos, job queues, evaluation harnesses, containerised deploys.
What are you available for?
