Yunus Yardım
Full-Stack & Mobile Developer · Istanbul
Full-Stack and Mobile Developer with 5+ years of experience building scalable applications across mobile, web, desktop, and backend platforms. I can carry a product single-handedly from idea to store: requirements analysis, architecture, interface development, database and service design, testing, release, and maintenance. I built a corporate e-HR application across four platforms on my own, owned the entire mobile side of a career platform serving thousands of users, and contributed to product strategy alongside technical decisions in ventures I co-founded. I value adapting quickly to new technologies, choosing the right tool for the job, and owning every line I ship. I hold a Bachelor's degree in Astronomy and Space Sciences from Erciyes University and am pursuing a Master's focused on data science with Python. I built CubeSats with the KaySat team and competed in TEKNOFEST.
