I see #indianyouth or #genz completely off track. So much emotion for #Saiyaara and making reels rather than focusing on career . Not sure whether these guys realise #ai is changing rapidly. By the time they realise they won’t be job ready. All entry level jobs will be wiped out.

🚨 What really drives customer satisfaction in airlines? I ran a correlation analysis on passenger survey data, and here’s what stood out: ✅ Higher seat comfort, cleanliness, entertainment & food quality → happier passengers. ❌ Economy class & personal travel show strong

🌾♟️ What does an ancient chessboard riddle about wheat have to do with modern AI? Surprisingly — everything. The way grains double across 64 squares is the perfect metaphor for how AI models scale — and why bigger isn’t always better. I broke this down in my latest blog

The new H-1B visa fee may feel like a setback, but it’s a blessing in disguise. 🇮🇳 India in 2025 is far more exciting than India in 2005 — booming startups, deep talent, digital infra. NRIs: Build here, invest here. The future isn’t abroad, it’s at home. 🚀 #H1B #India

🔍 Experimenting with Local LLMs using Ollama Just spun up Ollama inside Docker and tried running TinyLlama locally — and it works beautifully! 🎉 Even with limited resources, the model is able to generate coherent responses to prompts like "Tell me about Microservices" right on
