Integrated Prometheus MCP to develop Dify workflows, enabling AI models to statistically analyze resource utilization rates and provide optimization recommendations, resulting in cost savings and improved efficiency for the company. Actively assisted testing and development teams in resolving various operational challenges (such as permissions, k8s, S3 configuration, network connectivity, etc.), quickly solving complex issues to ensure team efficiency. Implemented fine-grained cost management for cloud resources (EC2) while ensuring business stability, achieving cost savings of over $100,000 USD compared to the same period. Optimized instance types and consolidated nodes to effectively reduce idle resources, improving resource utilization and elastic scaling capabilities. Led and completed the migration of test environment from AWS to Alibaba Cloud, covering overall system architecture, planning, and implementation, ensuring seamless transition of major services. Documented migration status and defined migration scope, providing foundational experience for subsequent production environment migration and multi-cloud strategy. Drove the development and optimization of automated cost reporting tools, significantly reducing time required for cost monitoring and analysis while improving data accuracy and decision-making efficiency. Implemented automated idle resource alerts (including idle resource monitoring and Grafana integration), proactively identifying resource waste and enabling timely remediation. Planned and executed seamless upgrades for Kubernetes (k8s) services including EKS, ACK, and other multi-cloud Kubernetes platforms, achieving zero business downtime while enhancing platform security and functionality. Strong cost awareness and automation practices, driving fine-grained resource management and continuous cost optimization.

I specialize in Python development, leveraging my skills to create chat bots aimed at streamlining Standard Operating Procedure (SOP) tasks for operations and maintenance personnel. My expertise lies in crafting efficient solutions that enhance workflow and ease operational processes. Responsible for implementing Jenkins Job Continuous Integration and Continuous Deployment (CICD) pipelines, enabling daily automated deployments to mitigate human errors. Revamped Elasticsearch index configuration, consolidating and deduplicating indices to mitigate disk space issues. This initiative aimed to enhance search efficiency by optimizing index structures and reducing unnecessary redundancy.

Used Jenkins pipelines to drive 30+ microservice project builds out to the Docker registry and then deployed to Kubernetes. Created Pods and managed using Kubernetes. Implemented trigger continuous integration (CI) jobs with Gitlab And Jenkins, Send a notification to Slack every time a job fails or success. Implemented DockerFile To Build up application Image, And using cache layer to speed up build time (raising 30%). Automated build and deployment using Jenkins to reduce human error and speed up production processes. Creating Ansible Playbooks to install the on-premise and Cloud (GCE) service for developer, including Kubernates, Elasticsearch, Kibana, Prometheus, Mysql, Kafka, Redis, Mongo, NFS, Istio, etc. Designing, implementing and supporting Continuous Integration and Continuous Delivery processes for development teams using Nexus, Jenkins Pipeline, Docker, SonarQube, ShellSctipt. Developing custom tools and automated deploy monitoring Dashboard, and Alerting for environments error, using tool: Kibana, Elasticsearch Alert, Prometheus Alert Manager, Slack Notification. GCP migration - on-prem VM hosts to GCP, building and provisioning GCP resources including GKE, CloudSql, Mongo Atlas. Automating backup and recovery processes disaster recovery including CloudSql and MongoAtlas. Optimising Elasticsearch Search Performance, turning index Management, sharding, scale up 3 Node, And Index Recycle Management (raising speed 40%). Using Helm Charts to pack all the required K8S components for an application to deploy, run and scale. It is also where dependencies are defined, and configurations are updated and maintained. Setup HorizontalPodAutoscaler, using load testing to estimate pod resource requests and limits to set max number pod. Setup HealthCheck (readiness Probe, liveness Probe, setup Probe) on kubernetes to ensure 99% uptime. Design Build Flow For Muti-Arch (arm64, amd64) Docker Image For Developer, Cause using M1 Mac. Migrated the local virtual machine host to GCP, including K8S and VM resources, such as GKE, Cloud SQL, and MongoAtlas.

In charged of NC machining simulation and monitoring system using the Augmented Reality (AR) technology. Design CAD mold, Making final integration Report.
