Jeremy Marc K.
QA Tester | Technical Support Lead | SaaS Operations
QA Tester and Technical Support Lead with experience in testing, live system support, and production monitoring. I help teams catch bugs early, troubleshoot issues, and keep things running smoothly—especially in real-world environments. I’ve spent the last few years working closely with QA, support, and live systems, so I’ve seen how small issues can turn into bigger problems if they’re missed early. I test software the way real users would, catch issues before they go live, and help teams figure out what’s actually causing problems when something breaks. 🔍 What I Can Help With QA & Testing - Manual testing (web, mobile, desktop) - Regression, smoke, and exploratory testing - Writing clear bug reports with steps and logs (so devs can fix things faster) - Creating and running test cases - Pre-release checks and post-release monitoring SaaS Support & Incident Handling - Investigating live issues and figuring out root causes - Working with logs, dashboards, and real production data - Handling tickets and keeping things within SLA - Helping reduce repeat issues by improving QA + support handoff Monitoring & Systems - Setting up and working with Datadog alerts and dashboards - Monitoring systems and catching issues early - Experience with Kubernetes-based setups - Basic AWS and Linux troubleshooting Team & Process - Led a team of 10+ support agents - Created SOPs and training materials - Helped improve communication between support and dev teams - Focused on reducing missed issues and improving response times 🧰 Tools I Use - Jira, GitHub, Zendesk, Slack, Shortcut - Datadog - Kubernetes, Docker, Linux, AWS (basic) 💡 Why Work With Me - I don’t just test—I try to understand how things break - I focus on real-world use, not just “happy path” testing - I can talk to both devs and non-technical teams without confusion - I try to solve problems early, not just report them after 📩 Let’s Work If you need someone who can: - Catch issues before your users do - Help during live incidents - Or improve your QA/support workflow Just send me a message and we can take it from there.
