Deep dives

Telegram Payment Gateway

read case →

One of the first ten Telegram Payment Gateway integrations in the world — a payment-orchestration platform went live as an early provider inside Telegram, shipped fast against a brand-new spec without cutting the corners that matter with real money.

  • PHP
  • Symfony
  • Redis
  • Telegram Bot Payments

Provider connector framework

read case →

A unified flow-action model that let a payment-orchestration platform onboard new acquirers and aggregators the same way every time — turning bespoke integrations into a repeatable contract.

  • PHP
  • Symfony
  • PostgreSQL
  • RoadRunner

3-D Secure 2.0 & SCA

read case →

Browser-based 3-D Secure 2.0 authentication wired through the payment gateway — PSD2 Strong Customer Authentication without breaking the checkout flow.

  • PHP
  • Symfony
  • 3-D Secure 2.0
  • PSD2 SCA

Payout engine

read case →

A payout flow that pushed money out across providers with the same reliability guarantees as taking it in — commit, confirm, reconcile, never double-pay.

  • PHP
  • Symfony
  • PostgreSQL
  • Queues

Card tokenization & hosted fields

read case →

PCI-safe card capture and reusable tokens — keep raw card data out of merchant systems while still supporting one-click and recurring payments.

  • PHP
  • Symfony
  • Redis
  • PCI DSS

Platform component framework

read case →

The shared libraries and contracts a payment platform's dozen services are built on — a typed object-mapper, domain primitives, query/criteria and versioned service contracts — so everything speaks the same language.

  • PHP
  • Symfony
  • DDD
  • CQRS

Fleet runtime & observability

read case →

Moved a dozen payment services onto a long-running PHP runtime, with standardized structured logging and metrics — so the fleet is faster, observable and production-ready on Kubernetes.

  • PHP
  • RoadRunner
  • Kubernetes
  • Monolog
