Hi there
I’m Aditya — a self-taught AI engineer from Nanded, India. I’m the guy behind AstraGPT, a 7B language model I built completely from scratch, and Astra AI Gateway, which serves 40+ models to real users every day. Before going full-time on AI, I spent 1.5 years at Supreme Group running industrial waterjet robots — yes, actual heavy machinery.
I love the whole stack: training models on my own GPUs at 2 AM, breaking web apps for a living (ethical hacking & VAPT), and shipping infrastructure that stays up. If you’re building something interesting — or want a model that doesn’t exist yet — let’s talk.
