Freelancer profile translated to English.

Description

I am a full-stack engineer specializing in TypeScript, SaaS, and Stripe payment architectures.

I help startups and marketplaces design robust, scalable products that are directly aligned with their business model. My expertise focuses on critical systems: payments, multi-vendor flows, application performance, and backend reliability.

I am particularly involved in:

• Implementation and optimization of Stripe and Stripe Connect for SaaS and marketplaces

• Design of secure and resilient payment architectures

• Reliable management of webhooks, subscriptions, split payments, and refunds

• Development of high-performance React applications and TypeScript APIs

• Reduction of technical debt and improvement of maintainability

Beyond development, I collaborate closely with product teams to structure solutions that support growth: payment funnel optimization, user flow simplification, and revenue security.

My goal is not just to deliver code, but to build technical systems that sustainably support product growth.
