Turnkey Digital Solutions
Your outsourced AI department
The work between the tools
The catalog lives in one place, customer questions arrive elsewhere, and someone still has to carry information between them. Choosing the tools and coordinating the work takes time.
One working system
You describe the business task. I design the path, connect the tools, build what is missing and take responsibility for the complete result.
The shared core
Seven directions use the same five layers. A new capability can build on the data and connections already in place.
01 Data
Documents, catalogs and operational records
02 Agents
Models and agents working with that information
03 Connections
CRM, store, email and business systems
04 Control
Approval, checks, logs and reports
05 Interfaces
Website, messaging, phone and apps
Seven directions
01 Sales Systems
Your customer gets an answer and places an order without waiting for a sales rep.
02 Outsourced Online Store
Storefront, catalog, orders and content, with one person responsible for the whole operation.
03 Company Knowledge and Internal Agents
Your team gets an answer with its source, and routine work moves forward.
04 Business Process Automation
The system handles emails, documents, orders and shipments. People make the decisions.
05 Brand Voice and Content Production
Your company or expertise has a recognizable voice, with content going out on schedule.
06 Interactive Apps
Your subject, method or product becomes an app people can use every day.
07 AI Personas
A character with a personality of its own, living in your product and growing with it.
Systems that grow together
Illustrative combinations. The concept defines the scope for your company.
Store + sales + content
Product information reaches the storefront, the assistant and the publishing routine.
Knowledge + process automation
Company information supports answers and agreed actions in operational systems.
Apps + AI personas
An interactive product gives a character a role, a place to act and scenarios to test.
How the work moves forward
Describe the task
Send me a message or an audio recording in your own words. Tell me what needs to happen, who will use the result and what gets in the way today. I clarify the details and put together the brief; source files can come later.
Receive my proposal
Within 48 hours of the brief, I send an initial concept. I choose the technology stack and explain how the system will work, what is included, the delivery stages, timing and cost.
Agree on the scope
You review the proposal and ask questions or request changes. We confirm the result, scope, price and acceptance criteria in writing, so you know what you are paying for.
Start the first stage
Once we agree, you pay for the first stage and provide the access and materials it needs. I confirm the start date and the plan. Each following stage is paid before it begins.
Build in stages
I connect the data, tools and interfaces, build what is missing and show you progress through previews and a short weekly report. We agree on the cost and timing of any new requests before adding them.
Test real scenarios
We check the complete path, including exceptions and the points where a person must decide. Acceptance is tied to the agreed scenarios.
Launch and hand over
I put the system into operation and hand over the code, accounts, access and instructions. You own the result.
Keep it working
With the agreed support in place, I monitor the system, resolve issues and develop it as the business changes. You see what the system has done in the monthly report.
Try the demo company
Seven fictional scenarios show how the parts connect. Open a demo, try its controls and follow the result.

Implemented work
NF ELIT website assistant
NF ELIT has an implemented website assistant for explaining its materials and services. When a request needs the team, the visitor follows the contact link and submits it directly.
NF ELIT internal assistant
An internal consultant connected to NF ELIT’s materials and real databases was created and implemented.
NF Prime
NF Prime automatically builds load plans around equipment constraints, payment terms and the pickup and delivery sequence. Version 11.0 uses one AI extractor; the remaining pipeline is code.
Children’s furniture on Amazon
The complete Amazon sales setup was delivered for a private client selling children’s furniture made from eco-friendly birch plywood.
Also: AI Academy, Modern Python, English ↔ Português and Truck Driver English. Personal projects with public demos and code.
Working terms
Payment by stage
Scope and cost are agreed before the build.
Acceptance by scenario
We test the complete path, including exceptions.
You own the result
Code, accounts, data, access and instructions are handed over.
Ongoing support
An agreed support scope and a monthly report of the work.
