I am a Software Development System Engineer with hands-on experience in designing, operating, and maintaining on-premise infrastructure that support modern software development of micro-services.
My work includes managing Dell EMC physical servers (R620, R640, R720, R740,supermicro)deploying and maintaining Linux systems (Ubuntu, CentOS), and implementing virtualization and storage platforms such as XCP-ng and FreeNAS such as NFS,SMB,ISCSI. Configured and managed DNS, DHCP, and Mail Servers to ensure reliable network and communication services.
Created and maintained VM templates and virtual machine snapshots for rapid deployment, backup, and disaster recovery. Implemented and managed RAID technologies to enhance data redundancy, storage reliability, and system availability.
I specialize in monitoring and observability, working with tools such as Cacti, Nagios, Smokeping, Grafana, Prometheus, Loki, Alloy agent and the ELK Stack to ensure system availability, performance, and proactive issue detection.
On the DevOps side, I maintain CI/CD pipelines using GitLab CI and Jenkins, and implement GitOps-based deployments with ArgoCD for Kubernetes and K3s environments. I customize and maintain Helm charts, update application configuration files based on developer requirements, and manage application deployments across different environments. Configured and modified Apache APISIX routes, upstreams, and plugins to support application routing and API exposure. I use Lens to monitor, troubleshoot, and manage Kubernetes clusters, ensuring reliable and efficient application delivery throughout the SDLC.
I also manage identity and access control through Microsoft Active Directory, LDAP, and Keycloak, integrating secure access for databases, middleware, monitoring platforms, and jump servers. My experience includes administering RabbitMQ, Node-RED, and databases such as MySQL, PostgreSQL, MongoDB, and In-memory data structure store, used as a database, cache, and message broker for Redis.
To improve reliability and efficiency, I actively use Ansible automation for system configuration, user provisioning, access management, and repetitive operational tasks.
I am passionate about automation, system reliability, and scalable infrastructure, and I enjoy bridging the gap between development and operations to deliver stable, secure, and observable systems.
