Hammed O.

Back-End developer in South Korea (UTC+9)

**Hello Dev**!! _Let's debug the bugs bugging your code!_ My coding journey started since the era of QBasic, Visual-Basic, advancing to embedded C, PHP, Matlab and now Python. As a young academic scholar with over 7yrs+ in the field of Web Backend Development, Computer Vision, Robotics and Machine Learning, I have found myself to be naturally passionate to render mentorship in these domains. I have years of offline, online and free mentorship with friends and colleagues, both in guiding upcoming developers and in code debugging sessions with experts in the field. Generally, my area of experience is in supervised and reinforcement learning (RL). Specifically for supervised learning, I have worked with image and time series data for classification and regression tasks. While for RL, I have formulated and implemented various application-based RL environments, ranging from gaming, robotics and agriculture. While the aforementioned experiences are on on-premise computing resources, I also recently added training and deployment on cloud resources to my experience—particularly the google cloud platform (GCP) services like vertex AI and BigQuery ML alongside their recommended data handling workflows. I will be highly delighted to extend my impactful code4all ideology through this platform.
