Hi, I’m Cybernetic-Ransomware

👨‍💻 About Me

I’m a Python backend developer with professional experience in building data‑heavy and service‑oriented systems. My work sits at the intersection of backend engineering, data pipelines, and DevOps, with growing hands‑on experience in applied machine learning.

I have over 4+ years of commercial Python experience, a solid DevOps foundation, and practical exposure to machine‑learning systems, especially vision‑language models and OCR‑based pipelines.

Before moving fully into software development, I worked in project management and industrial software implementations, which left me with an unusually high tolerance for legacy systems, unclear requirements, and reality.
