What I'm looking for

I seek backend or cloud-focused roles in payment systems where I can lead technical delivery, mentor teams, and drive cloud migrations and modernization.

I am a Systems Engineer with over five years of backend development experience focused on financial and technology sectors, specializing in Java, Spring Boot, Python and Kotlin.

I have led technical delivery for international payment projects, worked with financial messaging standards (SWIFT, ISO 20022, SEPA, NACHA), and driven platform migrations and modernization efforts.

I mentor and support cross-functional teams, perform requirements gathering, code reviews and cloud re-architectures, and I currently teach programming and software fundamentals as a lecturer.

I am pursuing a Master's in Software Architecture and hold cloud and agile certifications, committed to continuous learning and delivering reliable, compliant payment solutions.
