What I'm looking for

I seek backend or full-stack roles where I can build scalable cloud-native services, improve system reliability, and automate workflows in collaborative teams.

I am a backend-focused software engineer with hands-on experience building scalable Java and Spring Boot services, integrating payment and invoicing systems, and automating data workflows. I have delivered modular, domain-driven backend systems, implemented authentication flows, and migrated services to more reliable deployment environments.

My work has reduced recurring costs by replacing third-party invoicing, enabled automated end-to-end payment flows with PayPal and webhooks, and improved system maintainability through Clean Architecture and event-driven designs. I also build microservices with Python (FastAPI) and OCR automation to eliminate manual entry and streamline operations.
