Description

Stripe and payment systems specialist helping SaaS platforms, marketplaces and e-commerce companies build and stabilize payment infrastructure.

I specialize in Stripe integrations, subscription billing systems and multi-PSP payment architectures.

I design and implement payment gateway integrations (Stripe, Adyen, Worldpay, HiPay, Redsys, Dalenys, Revolut, Systempay) including subscription billing, webhook processing and payment lifecycle management.

My work focuses on building reliable payment flows and resolving production payment issues such as failing payments, broken subscription renewals, webhook inconsistencies and payment state synchronization problems.

Typical projects I handle include:

• Payment gateway integrations (Stripe, Adyen and other PSPs)

• Subscription billing systems and recurring payments

• Webhook architecture, idempotency and event reliability

• Payment system stabilization and debugging

• Chargeback and dispute flow design

• Payment infrastructure architecture for SaaS platforms and marketplaces

I have nearly 20 years of experience in backend systems and payment integrations, working with financial institutions, payment providers and large e-commerce platforms.

I’m often brought in when payment systems fail in production, subscriptions stop renewing, or webhook processing becomes unreliable.

I work closely with product and engineering teams to design payment systems that are reliable, scalable and safe for production environments.
