What I'm looking for

I'm open to relocating to Germany and looking to continue building backend and ERP integration systems, particularly Java microservices, NetSuite workflows, scalable APIs, and financial automation.

I build Java microservices and NetSuite integrations that automate complex finance and billing operations. At Deliverect, I work on SuiteBilling architecture for a restaurant-tech SaaS platform, including subscriptions, billing accounts, subscription lines, and charge models.

I built an external NetSuite invoice PDF service with Java, SuiteScript, RESTlets, and Google Cloud Storage, reducing invoice retrieval from 5–10 minutes to under one second. I also implemented payment-file approvals and SFTP delivery to Citi bank, plus subscription checks that prevent cancelled subscriptions from being invoiced.

At Nuitée, I architected a Spring Boot reconciliation microservice processing more than 3 million monthly multi-currency transactions between the platform and NetSuite. I automated statement reconciliation and payment-template generation, eliminating 40 hours per week of manual finance work, and migrated more than 300,000 financial records from Zoho to NetSuite.

Earlier, I modernized JEE systems into Spring Boot services, improved API response times by 70%, and built reactive APIs with Spring WebFlux. I also build with microservices, Kafka, gRPC, React, and TensorFlow across projects ranging from GPS tracking to medicinal-plant recognition.
