- Payment integration
Payment integration for your system
The customer pays and your system already knows. Nobody checks bank statements by hand.
What I integrate
Cards
Secure payments, no card data on your server.
Local methods
Pix and boleto in Brazil, confirmed automatically.
Subscriptions
Plans, renewals, cancellations and late payments.
Reconciliation
Every payment matched to the right order.
Stripe and other gateways
I've run Stripe and Asaas in production, with subscriptions, reconciliation and retries when a payment fails, plus crypto payments (ETH, USDT, USDC). I also integrate other gateways that have an API.
Card data stays with the gateway, never in your database.
How I work
We map the process first, then I write the code. That is why the price stays the same.
Free call
You tell me the problem. I tell you if I can solve it and roughly what it costs.
Process map
For bigger projects: BPMN diagrams of how it works today and how it will work. Fixed price, credited to the project.
Fixed price
Scope and price in writing. They don't change later.
Short deliveries
You see the system working at every step.
Everything in your name
You own the code and accounts. Maintenance only if you want it.
Who does the work
I'm Miguel Muñoz, a full-stack developer and AI specialist. I hold technical degrees in software development and in cybersecurity (UTN), and I'm studying AI Engineering. I build the whole system, from mapping the process to putting it live.
So security comes built in from day one: access only for those who need it, protected passwords and keys, your customers' data handled with care, and backups.
FAQ
Which gateway should I use?
It depends on your volume and how your customers pay. I compare fees for your case.
Will it work with my current system?
In most cases, yes. I check on the first call.
