Integrations
Any API. Your language. Your stack.
I integrate payment systems, AI models, maps, social platforms, and custom APIs into your existing product — using whatever language or framework you're already on.

Languages I deliver in
java.snippet
// Spring Boot — Stripe charge
@PostMapping("/charge")
public ResponseEntity<?> charge(@RequestBody ChargeReq req) {
Stripe.apiKey = env.get("STRIPE_SECRET");
PaymentIntent intent = PaymentIntent.create(Map.of(
"amount", req.amount(),
"currency", "usd",
"automatic_payment_methods", Map.of("enabled", true)
));
return ResponseEntity.ok(intent);
}How it works
Step 01
You share your stack
Send me your existing codebase or describe the framework and runtime you're on.
Step 02
I plan the architecture
Auth flow, rate limits, retries, error contracts — mapped before a line of code.
Step 03
Delivered, documented
Clean integration with tests, env config, and a README your team can hand off.
