engineeri walked into prolearn's bangalore office unannounced and ended up as an engineer on the video pipeline. ravneet singh founded the company after leading technology at vedantu and co-founding fc.one. prolearn had raised a $3.2m pre-seed and was turning jee and neet topics into generated lessons.
a useful lesson needs a script, equations, scene timing, assets, voice, and a render that survives a student's pause button. the pipeline has to carry notation cleanly from the first structured output to the final frame. you cannot hallucinate a jacobian in a jee video and call it a style choice.
that walk-in is in the bangalore note. the useful residue is the pipeline habit: keep every intermediate artifact, make a bad frame reproducible, and know which stage lied. i work with ravneet on stipend and credit, which is not enough to offset engine costs, and is heartening anyway.
