Profile: https://flows.cv/andreikassiantchouk

I'm a dedicated frontend leaning engineer that encapsulates developer ownership and cross-functionality.

I have a customer driven mindset, and it’s important for me to have a feedback loop with either the stakeholders directly or someone that closely represent the user base. I am conscious of measuring the success of features, collaborating closely with design and product, addressing ambiguities, and having priorities aligned in our workflow.

I find adventure in my ethic. I love breaking out of my comfort zone, picking up new things, and expanding my toolkit! I take great pride in reliability. I see things as ongoing - I'm always working to clean up, improve, promote maintainability, and make things easier for future work.

My ultimate goal is to do work that enables others.

When I'm not coding, I enjoy games that involve theorycrafting and meta-breaking strategies to keep me learning and keep things fresh.
