Junior Developer & Client Support Specialist with hands-on experience in building and maintaining backend web APIs (Django,Flask, FastAPI, WAMP), delivering responsive customer support, and performing thorough QA for both web and mobile platforms. I’ve contributed to multiple projects from the ground up handling requirement analysis, test case writing, and team coordination. Alongside backend and operational responsibilities, I’ve also worked on mobile apps using Kotlin, Java, Swift, and Flutter, ensuring seamless cross-platform functionality. Comfortable managing client communication, automation tasks (e.g., Raspberry Pi), and Dockerized deployments, I bring a well-rounded, practical skill set to every project.

15-Minute E-Commerce UX Test

He responds quickly and finished the work on time, but in my case I would like more attention and care, he is efficient but does not put too much enthusiasm into what he does.
