Different products, same skeleton. Here are the six layers that kept showing up in every AI system I built this year, and why each one exists.

They all arrive as messy PDFs. Here is the pipeline I use to turn them into structured JSON, and why I never send the raw PDF straight to an LLM.

Here is how I give AI systems a real memory, from turning messages into vectors to matching them with the right client and answering from that memory. RAG vector database embeddings AI memory LLM ai https://myselfraj.com/blog/privacy-before-inference https://myselfraj.com/blog/privacy-before-inference Mon, 09 Nov 2026 10:07:00 GMT If your AI reads health records or client email, the safest personal data is the data the model never receives. Here is how I remove PII before inference, and put it back after.

Here is the small provider layer I put in every AI product, so switching between cloud APIs and a local Ollama model is a config change, not a rewrite.

Here is the approach I built to read an app's code once and give the agent one skill per page, so a form takes one call instead of fifty.

AI agents can answer differently every time. Here is how I evaluate agents with test sets, head-to-head comparisons, multi-turn runs and a scorecard, before any of them reach a user.

Here is how a local, low-cost shorts pipeline works step by step - transcription with Whisper, picking the best moments, face-tracked 9:16 crops and burned-in captions.

Ten reports over two years tell a story. Here is how I build systems that track values over time, flag sudden changes and rising risk early, and explain them in plain language. health AI risk scoring time series explainable AI LLM ai https://myselfraj.com/blog/make-your-website-readable-by-ai https://myselfraj.com/blog/make-your-website-readable-by-ai Mon, 09 Nov 2026 10:01:00 GMT People now ask ChatGPT and Claude about you before they visit your site. Here is how I made mine readable by AI - a generated llms.txt profile, access for AI agents only, an "ask your AI" button, and one cache bug that taught me a lot. llms.txt AI SEO ChatGPT Claude Next.js ai https://myselfraj.com/blog/i-ll-help-you-out-vs-i-ll-clarify-this-for-you-an-engine-that-knows-the-difference https://myselfraj.com/blog/i-ll-help-you-out-vs-i-ll-clarify-this-for-you-an-engine-that-knows-the-difference Wed, 15 Jul 2026 08:54:00 GMT AI systems are everywhere now. Clients also use AI tools to write emails. We use AI while researching, writing replies, preparing documents, planning work, and many other things. A lot of our communication now comes through AI. And that is what I call human involvement. I love this. But we also need to save the trees. All right, back to my stuff. ai https://myselfraj.com/blog/scaled-server-for-high-traffic-app-around-25k-hits-daily https://myselfraj.com/blog/scaled-server-for-high-traffic-app-around-25k-hits-daily Thu, 12 Feb 2026 04:14:00 GMT Distributed Systems and Database Scaling scaling https://myselfraj.com/blog/all-about-rdbms-sql-or-benefits-and-limitations-of-sql-and-nosql https://myselfraj.com/blog/all-about-rdbms-sql-or-benefits-and-limitations-of-sql-and-nosql Fri, 09 Feb 2024 07:17:00 GMT Many modern applications often use both SQL and NoSQL databases together to get the best of both worlds! databases https://myselfraj.com/blog/how-to-share-anything-with-native-share-options-in-html-and-javascript https://myselfraj.com/blog/how-to-share-anything-with-native-share-options-in-html-and-javascript Fri, 09 Feb 2024 06:58:18 GMT The Web Share API is a valuable feature that can enhance your website's functionality and user experience.
