What I'm looking for

I seek senior engineering roles building scalable Java-based systems, with strong CI/CD and cloud integration, in collaborative, growth-minded teams.

I am a passionate, results-driven software engineer with a strong track record of delivering reliable, scalable, and user-friendly software solutions that improve organizational efficiency. I have hands-on experience in full-stack development, backend services, and cloud integration across enterprise projects.

I've worked as a Senior Developer and Java Developer on large-scale applications, implementing RESTful services, Keycloak authentication, CI/CD automation with Jenkins and CloudBees, and cloud integrations with AWS, Vega and HCP. I have driven performance tuning, database optimization, and modular clean-architecture initiatives while collaborating with onsite and offshore teams.

I value mentoring and cross-functional collaboration, and I focus on maintainability, security, and timely delivery. My background includes strong experience with Java (Struts/Spring/Spring Boot), Angular front-ends, relational and NoSQL databases, and automated deployment pipelines.
