What I'm looking for

I’m looking for a team where I can build and evolve backend services for high-loaded financial products—owning architecture, event-driven workflows, and reliability—while collaborating with analysts and engineering leaders to ship from scratch to long-lived maturity.

I’m a Senior Software Engineer with 8 years of experience crafting financial products as a backend developer. I focus on engineering high-loaded distributed services on the JVM stack, using domain-oriented architecture to keep systems reliable as they grow.

I’ve built and evolved services end-to-end—from launching products from scratch with Spring ecosystem plus modern DevOps/Cloud practices to improving long-lived platforms through refactoring and architectural roadmaps. Recent work includes an asynchronous, Postgres-backed loan pre-approval flow, installment-loan servicing logic, and scalable partner analytics, along with Kafka-driven asynchronous processing that reduced billing processing time by 35%.
