Fast-Paced Firefighting Mindset: Demonstrated ability to remain composed under pressure, triage incoming incidents quickly, and push targeted hotfixes under tight timelines., Angular Mastery: 4+ years of deep, practical experience building and debugging complex web applications using modern Angular (v12+). Thorough understanding of RxJS, Observables, component lifecycle, ChangeDetection strategies, routing, and state management. Node.js & REST APIs: Strong working knowledge of Node.js for diagnosing backend/middleware bottlenecks, analyzing server-side error logs, and fixing REST API payload/contract mismatches. AWS Cloud Familiarity: Direct experience navigating AWS environments (CloudWatch logs, API Gateway, S3, Lambda, EC2) to trace broken network requests, inspect logs, and locate failing services. skills: EC2,S3,AWS infrastructure,AWS Cloud,AWS environments,Angular,API Gateway,API,backend,Cloud Integration,CloudWatch,CI/CD,logging,database tuning,Datadog,deployment pipelines,AWS CodePipeline,Lambda,GitHub Actions,Core Java,Jenkins,memory leaks,microservices,middleware,monitoring tools,New Relic,Node.js,site reliability,RESTful APIs,REST APIs,REST API,routing,RxJS,Sentry,Debug,Debugging,Debugging Skills,Splunk,Spring Boot,web apps,Troubleshooting,problem solver,strategies,client-facing,Firefighting,production support,QA,state management,Root-Cause Analysis,sales engineering,server-side,Triage ## Description Active Firefighting & Triage: Rapidly isolate, reproduce, and resolve critical production and staging defects, with an emphasis on high-visibility demo issues and UI crashes. Heavy UI Troubleshooting (80%): Debug complex client-side performance bottlenecks, state management issues, broken components, memory leaks, and DOM rendering delays in an enterprise Angular application. API & Cloud Integration Debugging (20%): Inspect payload mismatches, authentication tokens, network timeouts, and middleware bottlenecks across RESTful APIs, Node.js services, and AWS infrastructure. Demo & Release Readiness: Partner directly with product, QA, and sales engineering teams to ensure client-facing demo environments remain stable, performant, and zero-defect. Root-Cause Analysis (RCA): Implement fast, surgical hotfixes to resolve immediate fires, followed by documented root-cause fixes to prevent recurring disruptions.
