Hi, I’m Anup Das

Applied AI Systems Architect, writing about system design, GenAI infrastructure and Python.

By day I design the moving parts that keep AI and backend systems running reliably at scale: system design, GenAI infrastructure, and a lot of Python.

AnupTechTips is where I write it down: clear, plain-language guides on AI architecture, large language models and the craft of building systems that hold up under real load.

Why this blog exists

AnupTechTips began with a small frustration. So much writing on AI and large-scale systems either floats on the surface or buries the real ideas under jargon. I wanted the opposite: clear, plain-language writing on AI architecture, large language models, data science, and the craft of building systems that hold up under real load.

The reason is also personal. Learning this field can feel lonely. Scattered docs, half-finished tutorials, and late nights spent piecing things together. Every time an idea finally clicked for me, I wished someone had explained it clearly the first time. AnupTechTips is my attempt to be that person for you.

So I write the way I’d explain something to a friend: open about the trade-offs, clear about the mistakes I’ve made, and never pretending the hard parts are simple.

My goal is simple, and it means a lot to me. I want engineers, data practitioners, and curious builders to understand modern AI and scalable systems deeply, not just well enough to copy and paste. If a single post here saves you a late night, or makes a hard concept finally make sense, then it was worth writing.
