What I actually do

One page, no job-title box. The work spans a few adjacent disciplines on purpose.

Mahadevu M P — "DevPutta," a vibe coder — is focused on data analytics, software development, and ML-driven insights, and interested in AI-assisted development. Currently exploring cloud & data platforms and ETL pipelines.

Outside of the core work: crafting, painting, and movies/series. Published researcher in IoT-based monitoring and machine learning. [ add current role / where you work, and how you got here — your words ]
