What I'm looking for

I’m looking for remote opportunities in QA Automation, Quality Engineering, or Software Testing where I can use my experience in automation, API, web, and mobile testing. I’m particularly interested in teams that value automation, CI/CD, and engineering excellence, while giving me opportunities to grow further into DevOps, infrastructure automation, and AI-driven testing.

I’m a QA Engineer with 9+ years of experience in software quality assurance, specializing in test automation, API testing, web and mobile testing, and CI/CD. I have extensive experience with Selenium, Playwright, Appium, Rest Assured, Postman, Java, Python, SQL, Docker, and Agile development.

Throughout my career, I have built reusable automation frameworks, achieved approximately 60% mobile test automation coverage, automated functional and regression testing, and integrated automated tests into CI/CD pipelines to improve feedback and release quality.

Outside of work, I maintain a hands-on homelab where I work with Proxmox, OPNsense, Docker, Linux, VLANs, networking, storage, virtualization, media services, and self-hosted applications. I use my lab to experiment with infrastructure automation, DevOps practices, monitoring, networking, and new technologies before applying what I learn professionally.

I enjoy solving technical problems and automating repetitive processes. I’m particularly interested in remote QA Automation, Quality Engineering, and DevOps opportunities, while continuing to develop my skills in PowerShell, cloud technologies, and AI-driven testing.
