Hoping to prove me and my skills. Finding different ways to do things is what i always look for! Wishing a happy and a great new year to everybody. </p> <h2> Portfolio </h2> <p><a href="https://pengu-205675755892.asia-south2.run.app/" rel="noopener noreferrer">https://pengu-205675755892.asia-south2.run.app/</a><br> I know that im not the best one out there but I'll try and I'll keep on trying till i reach my goal and this portfolio is the embodiment of my journey. My will to be successful and all the times that I have failed. </p> <p>--labels dev-tutorial=devnewyear2026</p> <h2> How I Built It </h2> <p>I built it purely using Antigravity, though getting started with it was a bit confusing but eventually I figured it out. I really liked the feature of antigravity where it scrolls the website and can identify the issues.</p> <h2> What I'm Most Proud Of </h2> <p>I really like the wall of failure on my portfolio website and the animation behind it, to be honest it was a bit hard to write the right prompt but it was worth it. Also it matters a lot to me and i believe everybody can relate to it because everybody at the beginning of the journey faces this phase.</p> <p><a href="https://pengu-205675755892.asia-south2.run.app/" rel="noopener noreferrer">Link to the website</a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F6jqy4ztx6so0k8com43z.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F6jqy4ztx6so0k8com43z.png" alt=" "></a></p> devchallenge googleaichallenge portfolio devnewyear2026 Himanshu Negi Sat, 17 Jan 2026 16:40:07 +0000 https://dev.to/himanshu_develops/rag-or-text-to-sql-10bc https://dev.to/himanshu_develops/rag-or-text-to-sql-10bc <p>I recently worked on a project. To better understand which method works better for us, it is very important to understand the nature of the database. The database I was working on consisted of 16 columns and 20,001 rows, all related to company addresses and a few other details regarding their statuses. I was tasked with fetching data according to user queries, but I had to ensure there was zero hallucination. The system also needed to support aggregate functions, such as calculating maximums and averages. Since the chatbot was developed as a Proof of Concept (POC), the database size was intentionally kept small.</p> <p>Now that I am clear on the requirements and the nature of the dataset, I'll explain my approach and would like feedback on how I can improve it, as I am fairly new to the trade. I opted for a Text-to-SQL architecture because it provides higher deterministic accuracy than RAG and can perform average, max, and other operations; this is what we wanted to use on the database as it was a core functionality of the chatbot. Furthermore, since there will be a maximum of 100 concurrent users and the database supports horizontal scaling without the computational overhead of re-indexing vectors, I believe it is a more efficient approach—especially since the type of dataset I am working on has columns (like 'capital') that might be changed frequently.</p> programming ai discuss security
