...full-stack developer who can look at my existing Java- and Python-based application, identify where machine learning will add the most value, and then build those features over the coming eight months.

I need a seasoned Java professional who can step in immediately and spend 2–3 hours with me each day. The focus is senior-level mentoring and hands-on help across three areas: reviewing and debugging my current code, shaping brand-new features, and steadily improving what already runs in production.
