i think Zrodha tech team is small, compact (less than 40 person, i think).
They dont hire enough and expand the team, or outsource some non-critical parts saying everything(well, almost everything) needs to be inhouse.
Hence they have a long list of TODOs which never gets done and the partial progress on any of these features gets upended by faster changes in regulatory or tech/software world. So they have to redo this allover, wasting time.
They are lost in a loop of analysis paralysis, though heir intentions are good. For a third person like me, intentions means measurable, perceivable action on the ground which is entirely missing.
One thing which is appreciated is their load/traffic handling strength which could have not been tested properly with other brokers which handle less volumes than Zerodha (I think SEBI should have a load testing grades like in ADAS automation lever 1 to 5, 5 being robust and 1 being vulnerable, where almost all brokers including the big-bank-broking houses like hdfcb, icicib, sbin and their clumsy interfaces would secure less than level 3)
Hope zerodha will start realizing this sooner, add people and resources in right places (viz. tech team) and start galloping sooner from the current crawling state.
