How technology supports your operations

Behind the customer experience, we connect support, business rules and data. The structure below shows how those parts work together.

Clientweb · mobile Edge / CDNCloudflare APIauth · rate limit Queuesworkers · jobs DataPostgres · Redis AI layerRAG · vector db Observabilitylogs · métricas · alertas · tracing
Edge firstContent and cache at the edge (Cloudflare) for low latency anywhere in the world.
Guarded APIAuthentication, rate limiting and validation before any business rule touches the data.
Async workQueues, workers and background jobs so the system doesn't stall under load.
Resilient dataPostgreSQL as source of truth, Redis for cache and speed under load.

about

Real engineering,
not improvisation.

Sartor Digital is a brand operated by AGS Consultoria e Participações Ltda., with technical delivery led by Giovanne Sartor and specialized partners engaged according to each project's needs.

I use AI as an accelerator, but what sustains a product is architecture, tests and observability. That's where my focus is — and it's what separates a system that can grow from one that breaks at the first spike.

Architecture primeiro

Documented decisions (ADRs), not improvisation at deploy time.

Production-ready by default

Tests, CI/CD and observability from the first commit.

Security & privacy by design

Sensitive data treated as sensitive — from the data model up.

No lock-in

The code is yours, the stack is open, any future team can evolve it.

From first contact to ongoing improvement

You follow decisions, deliveries and next steps. Each stage has an objective you can discuss and approve.

01

Understand the operation

Tell us the problem, the tools you use and what needs to improve. We identify where to start.

initial assessment
02

Define the first delivery

We agree priorities, scope, investment and timing. You know what is included before commissioning the work.

clear proposal
03

Build and follow progress

You receive phased deliveries and follow the system in a demonstration environment.

visible progress
04

Launch and evolve

We organize rollout, documentation and support. Further improvements follow an agreed plan.

continuity

What to expect from Sartor

Experience in customer service, credit and digital products, with Giovanne Sartor directly involved in delivery.

Direct contact

Speak with the person defining and implementing the solution, from assessment to support.

Clear scope

Agree the problem, first delivery, dependencies and acceptance criteria before work starts.

Project continuity

Source code, documentation and support options to maintain and develop the system.

security & compliance

Security is not an add-on

For fintech, healthtech and agtech, data is a responsibility. I treat it that way from the first line.

Robust authentication

OAuth and SSO where applicable, secure sessions and least-privilege principle.

Protected data

Encryption in transit and at rest; secrets kept out of code, in a config vault.

Privacy by design

Compliance considered in the data model — consent, minimization and retention.

Resilience

Rate limiting, queues and cache to handle traffic spikes without bringing the system down.

frequently asked

What people usually ask me

Send a message about your operation and the problem you want to solve. The first response identifies priorities and next steps. If we need an in-depth review of systems or data, we agree its scope before starting.

You receive the code developed for your project and the documentation agreed in the contract. Third-party services and components retain their own licenses and terms.

Delivery is led by me, with a network of partners for demand peaks. What reduces risk isn't team size — it's engineering: documented code, automated tests, infrastructure as code and a full handover. Nothing stays locked in one person's head.

Timing depends on scope, integrations and required access. Before work begins, we agree on a phased schedule with deliverables you can follow and review.

Yes. We work remotely across Brazil and internationally, with delivery demonstrations and online meetings in Portuguese, English or Spanish.

Security by default: robust authentication (OAuth/SSO where applicable), encrypted sensitive data, least-privilege principle and privacy compliance considered from the data model.

Initial assessment

Which task or system
is holding your operation back?

Tell us what happens today and what you want to improve. The first response helps identify priorities and the next step. If an in-depth assessment is needed, we agree its scope before proceeding.
