About Issac Carlos

I’m a Performance Engineer and MBA graduate with 20+ years of experience spanning software testing, development, and backend engineering. I prioritize practical implementation over theory, drawing on Shift-Left Performance Testing, Site Reliability Engineering (SRE), and Chaos Engineering to build scalable, high-performing applications. I apply proven concepts and tools to deliver real-world results.My workflow includes continuous performance testing in CI/CD pipelines, ensuring each release withstands real-world loads. By integrating logs, metrics, and traces, I catch bottlenecks early and iterate rapidly for reliability.Key Areas of ExperienceMethodologies• Shift-Left Performance Testing, Continuous Performance Testing, SRE Principles, Infrastructure as Code, Serverless & Event-Driven.Chaos Engineering & Resilience Testing• Gremlin, Litmus, Chaos Mesh, Toxiproxy, AWS Fault Injection Simulator, Azure Chaos Studio.Backend & Languages• JavaScript/Node.js, C/C++, C#, Scala, Python, Golang, Java, Rust• Microservices, API gateways, service mesh (e.g, Istio), and event-driven architecturesSCM / Bug TrackingGitHub, GitOps, Bitbucket, GitLab, JIRA, Azure DevOps, TeamTrackDatabases & Storage• MySQL, MSSQL, PL/SQL, MongoDB, ElasticSearch, NoSQL (Cassandra, DynamoDB), sharding, partitioning, and caching (Redis, Memcached)Cloud & Containerization• AWS, Azure, GCP for multi-cloud/hybrid setups, Docker, Kubernetes, Helm to orchestrate containers at scale, Serverless (AWS Lambda, Google Cloud Functions) for cost-effective scalingDevOps & CI/CD• Jenkins, GitLab CI, Azure Pipelines, GitHub Actions, IaC with Terraform, Ansible, Chef, Puppet, Blue-Green and Canary deploymentsPerformance Testing & Scripting• LoadRunner, JMeter, CloudTest, Gatling, Locust, k6, Taurus, API load testing, front-end performance (Web Vitals), and protocol-level scripting, Service virtualization and mockingMonitoring & Observability• Splunk, New Relic, Datadog, Dynatrace, Nagios, Wily, Prometheus, Grafana, OpenTelemetry, SRE techniques for reliabilityProfessional Focus• Comprehensive Tests: Designing user-centric performance tests for microservices, event-driven systems, and legacy apps• Cross-Functional Collaboration: Embedding performance checks across DevOps pipelines• Data-Driven Optimization: Using real-time metrics to refine throughput and maintain uptime• Resilience & Innovation: Employing chaos experiments, feature flags, and stable deployment methods• DevOps & SRE Alignment: Championing observability and automation for measurable, scalable improvements.

Experience

1. Performance Engineer Ii

   Sony Interactive Entertainment

   Jan 2022 — Present · San Diego, US

   Support engineering teams across the organization in developing end to end performance testing frameworks for non-production and production environments. Contribute in leading efforts for the Engineering Enablement team, providing tooling, methodologies, and guidance to the other engineering teams. Partner with teams in order to define tooling methodologies, conduct scripting and tests for end-to-end user experiences, identify any bottlenecks along the way, and ultimately execute and push to production.
