What I can help with
I help companies build production AI systems with agents, open models, and modern AI infrastructure, from proof-of-concept to deployment.
| Service | Good for | What I can help with |
|---|---|---|
| AI Agents & Workflow AutomationBuild AI agents that understand requests, use tools, work with company data, and execute real workflows. | Good forCustomer support, research, document processing, operations, lead qualification, internal tools, and business process automation. | I can help with
|
| Private & Open Model AIRun AI models on your own infrastructure when privacy, control, or cost matters. | Good forEvaluate and deploy open models such as Qwen, Gemma, and other small or large language models on local GPUs or cloud infrastructure. | Services include
|
| AI Backend EngineeringTurn an AI prototype into a production-ready system. | Good forThe backend infrastructure needed to reliably operate AI applications at scale. | This can include
|
| Fine-Tuning & Small ModelsNot every problem needs a large language model. | Good forFor classification, routing, moderation, intent detection, extraction, and similar high-volume tasks, smaller specialized models are often faster and significantly cheaper. | I can help with
|
| AI Proof of ConceptHave an AI use case but not sure what architecture or model to use? | Good forA focused POC on your real workflow and data to determine what actually works before you invest in a larger implementation. Validate the approach with working software and measurable results. | A typical POC evaluates
|
| AI Engineering DiscoveryFor teams still figuring out where AI fits. | Good forA focused technical discovery engagement. You leave with a clear technical direction instead of a generic AI strategy deck. | We work through

Let's build.
Building an AI product, exploring open models, or automating a workflow? I can take it from idea to working system.
What is a Fractional CAIO?
A Fractional CAIO (Chief AI Officer) is a senior AI leader you engage part-time: agenda, guardrails, and build decisions without a full-time C-level seat. Mine comes with AI engineering attached, so the strategy and the code come from the same person.
Who this is for
Teams that know AI matters, have something to build, and are not ready for a full-time hire.
Founders and exec teams
You want a senior AI voice in leadership meetings, and someone who can build what gets decided.
Past experiments, no agenda yet
You have tried copilots, vendors, or a pilot. You lack a clear agenda and someone to hold the line on it.
Not ready for a full-time CAIO
You want more than a workshop, without creating a new C-level seat yet.
How to engage
A scoped build, ongoing leadership, or a lighter advisory start.
AI Engineering project
I scope and build an AI agent, local model deployment, or AI workflow for your business.
- Defined deliverables and timeline
- Working software early, regular demos
- Production at the end, not a prototype
- Can continue as a retainer
Fractional CAIO retainer
A senior engineer-exec in the loop with your leadership team on the AI agenda.
- Weekly, biweekly, or monthly cadence
- Decisions, guardrails, and build direction
- In the room with execs and builders
- Hands-on when it is time to ship
AI Adviser
A sounding board when you mainly need reviews and pressure-testing.
- Review strategy, vendors, build vs. buy
- Pressure-test a plan before you commit budget
- Office hours or a fixed number of calls
Customized. Not a package.
We design the engagement around how your team actually works.
Cadence & calls
Weekly, biweekly, or monthly, plus how reachable I am in between.
Scope
A single build, advisory, or a retainer that mixes both.
Depth
Leadership only, or in the room with the team on architecture and pilots.
Duration
A 30-day trial, a quarterly retainer, or a project with a finish line.

Engineer-led. Not slide-deck-led.
Melvin Vivas · AI Engineer and Adviser
25 years across banking, fintech, and enterprise, including senior roles at Standard Chartered Bank and Ohmyhome (Nasdaq). I still build, so in a leadership meeting I can tell a real system from a demo, and stay close enough that it ships.
AI Engineering and Fractional CAIO FAQs
AI agents, local models, and AI workflows. Agents with memory, tools, and skills that do real work; open models deployed on your own hardware so data stays in-house; and LLM pipelines and automations wired into the tools your team already runs. Shipped work includes the Codex Astra/Luna Orchestrator, Coworker, AI Backends, and Local Evals.
