What I'm looking for

I’m looking to build and modernize cloud-native microservices and enterprise platforms—owning architecture through production, with strong CI/CD, infrastructure as code, and a focus on scalability, security, and high availability.

I’m a Senior Java Full Stack Engineer with 13+ years of experience designing, architecting, and delivering scalable cloud-native applications, distributed systems, and enterprise platforms. I specialize in backend engineering, platform architecture, and DevOps-driven development, using Java, Spring Boot, React, SQL databases, and modern cloud technologies like AWS and Azure. I’m hands-on across the full SDLC—architecture, development, deployment, production support, and system optimization.

Across my roles at AktaryTech, Saucey, and earlier contracts, I’ve led technical delivery by translating complex requirements into production-grade solutions. I’ve designed microservices and event-driven architectures with Kafka, implemented application security with OAuth 2.0/JWT (RBAC), and improved performance through database tuning in PostgreSQL, SQL Server, and Oracle. I also build reliability into delivery by implementing CI/CD pipelines (Jenkins, GitHub Actions, Azure DevOps), infrastructure as code with Terraform, and containerized deployments with Docker, Kubernetes, and Helm to enable high-availability, zero-downtime releases.
