Freelancer profile translated to English.

Description

I am a Senior Business Analyst with over 8 years of experience in the Fintech and E-commerce sectors, specializing in payment systems, API integrations, and digital product development.

For the last 3 years, I worked at a payment processing company.

Responsible for own activities for over 20 complex payment functions.

Developed and implemented Google Pay, Apple Pay, card tokenization, recurring payments, embedded payment pages (HPP/SCI), A2A transfers, QR payments (NBU standard), pre-authorization processes, and full merchant self-service portal.

Integrated over 50 merchants and tested over 100 REST API endpoints with Postman – each of them was released to production without critical errors.

Previously, I spent four years at a private bank as a graduate – the largest bank in Ukraine – working on one of the largest POS terminal networks in Europe (over 200,000 terminals).

During this time, I developed 20 new processes together with a team of 40 developers.

I was promoted from Junior to Mid-level Graduate.

What I bring to your project:

→ Profound knowledge in payments (acquiring, card issuing, card schemes, open banking)

→ Solid understanding of APIs: clear specifications, careful testing: bridge between business and development

→ Agile development: Jira, Confluence, client support, managing open requests – my daily tools

→ Structured, self-reliant way of working with full responsibility for results

I live in Karlsruhe and am available for remote projects across Europe.

As well as for on-site assignments in the Karlsruhe region / in Baden-Württemberg.
