What I'm looking for

I seek a leadership engineering role focused on building cloud-native, scalable systems with strong DevOps practices, collaborative Agile culture, and opportunities to mentor engineers.

I am a results-oriented Senior Java Developer with 10 years of experience building and deploying enterprise-scale applications. I specialize in Java, Spring Boot, Hibernate, microservices, and cloud platforms, with a strong focus on performance, scalability, and secure coding practices.

At InsyteGroup I led the migration from monoliths to microservices, implemented OAuth2.0 and JWT for security, and introduced DevOps practices with Kubernetes and Jenkins that reduced deployment errors. I have a proven track record of optimizing systems to improve throughput and reduce latency for high-volume transactional systems.

I have mentored and coached engineering teams, improving productivity and reducing defects, while collaborating with stakeholders to define technical roadmaps and deliver complex projects. My hands-on experience spans CI/CD automation, Redis caching, asynchronous processing, and cloud migrations across AWS, Azure, and GCP.

I hold an OCP Java SE 11 certification, AWS Developer Associate, and Scrum Master certification, and I bring a pragmatic, engineering-led approach to designing robust, maintainable systems that drive business outcomes.
