Sumbleen Javaid Cheema
@sumbleenjavaidcheema
Customer-focused Technical Support Engineer specializing in Linux and AWS troubleshooting.
What I'm looking for
I’m a Technical Support Engineer who turns complex technical issues into simple, reliable solutions. I’ve handled 40 to 60+ support tickets daily, troubleshooting Linux systems and core AWS services (EC2, S3, RDS) to restore user access and performance.
In my L1 role at Crossover (Trilogy), I provided L1 technical support across Linux and AWS (EC2, S3, RDS, Lambda, IAM). I triaged and resolved tickets using Zendesk, maintained clear incident records and documentation, and supported faster handoffs through sharp technical reporting.
I also manage MySQL user administration and basic database troubleshooting, and I monitor systems with CloudWatch. I enjoy improving user experience—through structured prioritization, step-by-step debugging, knowledge base articles, and troubleshooting guides that reduce repeat tickets and onboarding friction.
