What I'm looking for

I am seeking impactful backend/cloud-native roles where I can own scalable microservices, improve system reliability, and drive integrations with modern DevOps practices.

I am a proactive Senior Software Engineer with 5+ years of hands-on experience building Java-based microservices, high-throughput messaging systems, and cloud-native deployments. I focus on designing scalable APIs, enterprise integrations, and reliable asynchronous systems that meet demanding production needs.

At IFS R&D I engineered Quarkus microservices, extended OData APIs for advanced LLM query support, and implemented multi-location SMB-backed file storage with dynamic PV/PVC provisioning. I built priority-based file scanning using Kubernetes leader election and strengthened CI/CD through Helm, Jenkins, and Bitbucket Pipelines.

Previously, I delivered highly reliable SMS microservices for major banks, migrated legacy systems to Spring Boot and MongoDB, and integrated monitoring via Grafana. I take ownership of performance optimization, security hardening, and cross-system integrations using middleware like Boomi.
