Writer. Researcher. AI Professional.

I am a Content & Technical Writer with 9 years of experience helping organizations communicate complex technology with clarity and confidence. I specialize in artificial intelligence, machine learning, data science, and software engineering.

Since 2020, I have partnered with international startups, SaaS companies, and AI organizations through Upwork, earning Top Rated status with consistent 5-star reviews. I have published 140+ articles on Medium, founded Mindful Data Science, and contributed to Good Vibes Club, Never Stop Writing, and Catharsis.

Alongside writing, I am pursuing a Master's in Data Science at Meru University of Science and Technology and evaluate frontier language models at Turing. My research focuses on AI-powered computer vision for medical diagnosis using ResNet50V2, EfficientNetV2, and CoAtNet.

I do not just write about AI. I build with it, evaluate it, and understand it at a technical level that most writers simply do not.
