Professional Summary

I'm a hardworking and highly autonomous individual with a very deep passion for Quality Assurance and Engineering. I enjoy challenging myself and working in areas in software that I am unfamiliar with or have a very deep interest in.

I've worked for various companies and startups; with products ranging from PoCs and MVPs to large production systems in fintech and financial forecasting. My focus has been on automation, leadership and continuous process improvement.

I'm also the founder of OmniLens, an open source tool for monitoring and optimizing your GitHub Action workflows. This is my first step into the world of solo development and I plan on building a lot more tools in the future.

When I'm not coding or testing, you'll find me exploring new technologies, listening to music, posting on X and gaming.

At Entersekt, I grew from a Junior QA Engineer to a Senior and learning the foundational knowledge I needed to become a solid QA Engineer.

From 2016 to 2018 I joined the mobile team where I was responsible for testing our SDK and mobile apps. All testing was manual and I had to test the same build across multiple devices with multiple operating systems. I build and maintained manual test suites that were easy to follow and scale when we needed to.

In 2019 I joined the backend team where I tested against physical appliances as well as their management console. I was responsible for planning, coordinating, executing and reporting on our bi-annual release cycles. I also started coding for the first time and build a VuePress documentation site for storing our test suites and test plans.

From late 2019 to 2021 my focus moved from one team to all teams within engineering. This gave me the opportunity to grow my leadership skills as well as mentor our other QA Engineers.

During this time I was also the Scrum Master for the DevOps team and responsible for facilitating backlog refinement sessions with the QA engineering team.

Key Responsibilities:
Collaborating with Agile development teams to define and implement product test strategies
Proactively driving quality improvement through metrics and reporting
