AzerbaijanWhat I'm looking for
Senior Java Backend Engineer with nearly 10 years of experience building banking, payments, and fintech systems.
I specialize in Java, Spring Boot, distributed systems, microservices, payment workflows, and event-driven backend architectures. At Guavapay, I owned backend delivery for customer-facing fintech capabilities, designing cross-service payment flows and taking features from requirements through production.
Across fintech and banking, I’ve worked on payment platforms, corporate lending, internet banking, and instant-payment systems, with hands-on experience in production reliability, cross-service incident resolution, external integrations, and end-to-end backend delivery.
I also mentor backend engineers and contribute to technical decision-making while remaining deeply hands-on with implementation.
