CANER / SENIOR QA ENGINEER

Look closer.
Think wider.

Senior QA Engineer / Test Automation Engineer working across UI, API and database boundaries, with experience in financial platforms and web applications.

Caner

From a finding
to a better decision.

My work starts with understanding the problem. I look at real user behavior, edge cases, regression risks and product reliability. When investigating issues, I separate confirmed evidence from assumptions and explain technical findings in language people can act on.

Why Towlar exists

Towlar brings this way of working into a broader setting. Consulting helps teams approach quality with more clarity. Product development gives ideas a concrete form. Collaboration opens a path for other developers and product owners to build alongside that work.

AI with a practical role

I use LLMs to analyze requirements, identify ambiguous business rules, develop edge cases and draft focused API/UI checklists and bug reports. I verify conclusions against source evidence and separate confirmed findings from untested assumptions.

Context before solutions

Understand the problem, the user and the product before deciding what to change.

02

Evidence before assumptions

Separate what has been verified from what still needs investigation.
