Building a Tailor ERP Shipped this week: Customer Management Order Management Frontend ↔ Backend Integration Tailors can now manage customers, measurements, and orders from one dashboard. Still building. More coming soon. #buildinpublic #NextJS #PostgreSQL #FullStack

Built the auth + clothType system for a tailor ERP: → JWT auth + protected routes → Session handling → Dynamic measurement fields by cloth type → Auto-adapting forms for tailors No more manually managing measurement forms. #buildinpublic #Nextjs #Postgres #freelancedev

something different happened this week closed my first freelance deal 🤝 building a mini ERP for a local business few months ago i was just grinding tutorials now someone's paying me to build their system keep building. 🚀 #freelance #webdev #buildinpublic #developers #coding

Just watched Hitesh Choudhary’s AI Agents in-depth session Now I finally understand: • AI agents • their history • different ways to approach them Also revised a lot of JavaScript concepts along the way

Deep dive into JavaScript fundamentals — closures, event loop, async flow + core Node.js. Focusing on strong fundamentals over surface-level knowledge. Preparing for internship opportunities Back to AI part soon. #javascript #nodejs #internship #buildinpublic

Learning web scraping—how HTML, selectors & dynamic content work. Now thinking of building a scraper to gather hiring data + automate outreach. since I’m actively looking for internships. Building systems > manual search . #buildinpublic #webscraping #internships

@aniketwarule1 Just curious ,how do you usually find emails, and what’s your criteria for identifying the right person to reach out to?

Day 8 of posting until I get a job days like this give me more power got 2 replies 🥹 cold mails doing the thing still continuously looking for new opportunities not settling on just this Manifesting the day when I post a career update here 😭

@stackychan_ Yeah, I’m in 3rd year too Let’s connect , DM me!

@0xmadhur Lets prepare together man. We can do it. Are you from 3rd year too ?

GSoC 2026 results just dropped. 1141 people were selected out of 15k+ applicants As for me, I completely wasted the first 2 years of my degree not taking things seriously 🥹. This year, I didn't even apply because I'm still in my learning phase But that’s exactly why I'm building in public now. My dream is to get selected for GSoC '27 (my final year). Next year, we're in 🫡

Built an AI agent loop from scratch (no LangChain): → ReAct (think → act → observe) → Tool calling + memory → Loop guard + stuck detection → Error handling CLI agent that researches & summarizes any topic. Now I actually understand agents. #BuildInPublic #AI #LLM

Finished Tool & Function Calling 🔧 → JSON schema tools → LLM decides: tool vs text → Full loop: call → run → return → Sequential vs parallel Built Node demo: “Tokyo population × 3” → search → calculate Now LangChain makes sense. #BuildInPublic #AI

@yabsssai I chose pgvector mainly for simplicity and integration. Using it meant that I could handle both structured data and embeddings. For my use case, it offered good performance,easy to set up, and reduced complexity. If I were scaling to millions , I'd consider something else.

@0xmadhur i'm curious about the decision to use pgvector as a vector store, what made you choose that over other options for your RAG chatbot project?

Just wrapped RAG & embeddings: → Learned how embeddings turn text into meaning-rich vectors → Set up Supabase + pgvector as a vector store → Built the full pipeline: retrieve → augment → generate → Ended up with a working RAG chatbot (built from scratch) #BuildInPublic #AI

@Markgonzal50858 yeaa must be down

@0xmadhur Mine isn't working too

Is everyone's claude is down or is it just me?

Been going deep into LLMs lately: → Understanding how they work under the hood (tokens, context windows, temperature) → Built a multi-turn chatbot with streaming, conversation history, and structured outputs Next up: RAG & embeddings #buildinpublic #AI #LLM #developers

System Design revision Things I'm going deep on: → Scalability patterns → Distributed systems design → Caching & CDN strategies → Message queues & event-driven arch The fundamentals never get old , they just get clearer. #SystemDesign #BackendDev #InterviewPrep

Been off Twitter for a while, but I'm back! This time with a plan ,diving deep into system design, picking up new skills, and starting my internship hunt from May. Let's see where this goes 👀

@GuptaSayujya Happy birthday

Everyday 1000s of job posts are posted on X, Yet you can't find any, cause X search sucks. So, I built an app that finds out all the recent jobs for you. I could easily charge $40/month for this But today I'm giving it away for FREE (cause it's my birthday) How to get it? - Follow me - Repost this post - Comment "Happy birthday" And I'll share the link with you. This is how it works:
