Help me decide if I should invest in Nova by Raghava

Was looking at this Nova by Raghava project in Financial District because those huge 61 floor twin towers looks crazy on the hoardings. But honestly I am quite confused if it is even a safe bet to put money there. I was checking some things online and apparently this builder hasn't actually delivered any major residential project fully till now? Like everything they started is still under construction, even that Iris project in Gachibowli... actually I think that is also under construction still. Booking in a new launch when there is no solid track record of final possession feels bit risky to me, not sure though.

And that road right in front of Nova is just so horribly congested anyway. Traffic there is becoming total mess. I went that side last week and there were so many water tankers and half built roads right next to these luxury high-rises. Plus they are squeezing so many flats in just 7 acres, the density looks crazy. Carpet area and layout looks big on paper but will we even get decent appreciation later with so much supply coming up nearby? There are literally so many other options from older builders right there. Maybe I am wrong, just what I noticed while looking at some listings. Anyone else seeing this or having doubts?
