About Sergiu Valcan

I’m a hands-on DevOps engineer who turns complex infrastructure challenges into repeatable, self-healing solutions. My sweet-spot is end-to-end automation on AWS—codified in Terraform and orchestrated with GitHub Actions/GitLab CI—to ship reliable, secure environments at the speed of business. What I bring to the table Cloud & IaC: Architect and operator of full-stack AWS and hybrid Azure estates, expressed as clean, reusable Terraform modules. AWS Toolkit Mastery: • Compute – EC2 fleets, Auto Scaling, ECS Fargate, Lambda, EKS • Data & Messaging – MSK (Kafka), RDS (MySQL & DB2), ElastiCache, DynamoDB, S3 • Search & Analytics – OpenSearch, Athena • Networking & Security – VPC, Gateway, ALB/NLB, WAF, IAM, KMS • Monitoring & Mgmt – CloudWatch, CloudTrail, Systems Manager, Config CI/CD Excellence: Multi-stage pipelines that lint, test, scan, build, and promote artifacts automatically, shrinking release cycles from days to minutes. Container & Runtime Ops: Dockerized microservices built with Maven/Spring Boot and Electron apps—rolled out with zero-downtime strategies. Observability: Full Datadog integration (metrics, logs, APM, dashboard, traces, synthetics) plus ELK/Elastic Stack for nuanced troubleshooting and capacity planning. Integration Platforms: Axway B2Bi, WSO2, ActiveMQ, NGINX, IBM WebSphere—delivered on both Linux and Windows Server, with automated monitoring and SLA reporting. Domains Served: Automotive, pharmaceutical, and telecom, where compliance, traceability, and performance are non-negotiable. People & Process: Former Customer Service Supervisor—skilled at translating technical detail into clear business value, mentoring cross-functional teams, and keeping stakeholders in the loop. I thrive on green-field builds, tight feedback loops, and the satisfaction of watching a one-click pipeline create a production-ready environment—all while everyone else is still brewing coffee. Let’s connect if you need to harden cloud infrastructure, tame release pipelines, or illuminate your systems with first-class observability.
