I built ShaadiBiodata.in: create a marriage biodata in minutes
Just shipped ShaadiBiodata.in I built it to make creating a professional Indian marriage biodata much simpler. Instead of editing Word files or struggling with formatting, you can: - Fill in your personal, family, education & career details - Choose from multiple marriage biodata templates - Preview everything instantly - Download your biodata as PDF/JPEG - Create it directly from your phone There’s also a free download option, so anyone can try it before paying for a higher-quality version. https://shaadibiodata.in I’m currently improving the templates, mobile UX, performance and SEO. Would love some feedback — especially on the biodata creation flow and template designs.
Building Jobsly: AI Job Application Autopilot
🚧 Building Jobsly — an AI Job Application Autopilot I’ve been working on Jobsly , an AI-powered job application assistant designed to make applying for jobs much less repetitive. The idea is simple: → Jobsly analyzes the job description with AI → Understands how well the role matches your profile → Opens the application flow → Automatically fills repetitive fields → Uses AI to generate relevant answers where needed → Helps you move through applications much faster We already have autofill support working for Greenhouse and Workday , and I’m currently working on adding more job providers and improving the autopilot flow. It’s still under development, so this isn’t a launch announcement yet — just sharing what I’m building. 🛠️ Planning to open it to the public soon. 🌐 https://jobsly.pro Would love to hear what feature you’d want in an AI job application copilot. buildinpublic ai jobs automation jobsearch chromeextension saas
Your CLI could handle your entire API workflow
Hello world devs! Imagine being able to create, test, debug and chain APIs right from your terminal No Postman. No switching tabs. Just your CLI. So... I came up with APIX. It's a CLI tool I've been building to make working with APIs a little easier You can: - Run GET, POST, PUT, PATCH & DELETE requests - Generate API requests using AI - Save and reuse requests - Manage environments & variables - Chain multiple APIs into a single workflow For example: "POST login → GET credentials → PATCH profile → POST orders → GET confirmation" ...all as one chain. It's still very much a work in progress, but I'm pretty happy with where it's going. Would love to know what you guys think... and what you would add to something like this GitHub: https://github.com/Aayush4518/apix npm install -g apix-dev-cli
Building Selah: A Modern Offline Bible App with Flutter 📖
🚀 I built a Bible app with Flutter over the weekend. I’ve been working on something I’m really excited about Selah. I wanted to build a Scripture experience that feels calm, beautiful, and intentional, while still being fast and fully usable offline. Here’s what I ended up building: 📖 7 complete Bible translations bundled directly into the app, with 31,000+ verses each. I used Dart Isolates to handle the parsing in the background so it doesn’t slow down the UI. 🔥 A custom 3D-style onboarding experience built entirely with Flutter’s CustomPainter —68 ember particles, 90 twinkling stars, aurora effects, floating Scripture cards, parallax and depth. No 3D engine. 🏗️ A proper app architecture using Riverpod, GoRouter with StatefulShellRoute.indexedStack, and a feature-first structure across 25+ screens. 📚 A full Bible reader with highlights, bookmarks, notes, sharing, text-to-speech, translation comparison, and saved reading progress. 🌍 6 UI languages — English, Yoruba, Igbo, Spanish, Portuguese and French. ⚡ One of the things I’m happiest about: it works completely offline. The translations are bundled, parsed once, and cached so you can just open the app and read. There were also a lot of small things that aren't as exciting to post about notification permissions, preference migrations, APK optimization, testing, fixing bugs, and making sure everything actually works together. The weekend went by pretty quickly 😂, but it was genuinely fun building this. Selah is still a work in progress, but I’m really happy with how it’s coming together. 🔗 View my LinkedIn post: https://lnkd.in/p/eFTUQeTT 🔗 Try Selah / Download the APK: https://lnkd.in/ehD6u2Cf 💻 GitHub Source Code: https://lnkd.in/eeiwEtni Tech: Flutter · Dart · Riverpod · GoRouter · Isolates · flutter animate · flutter tts · Dio · SharedPreferences Flutter Dart SoftwareEngineering MobileDevelopment FlutterDev BibleApp BuildInPublic

InvoiceDeck: Design-first invoicing & client cash flow protection for freelancers
Hey everyone! Built this out of frustration with clunky enterprise invoicing tools that feel like software from 2008 and generate ugly PDFs. InvoiceDeck is a lightweight, design-focused invoicing app built specifically for developers, designers, and freelancers. Key things I focused on: • 9 design-first themes: Including a dark Terminal monospace layout and a clean Swiss Bauhaus style. • Zero-touch payment protection: Turn accepted estimates into 50% deposit invoices in 1 click, with automated late fee penalties if clients blow past grace periods. • Global compliance: 1-click tax presets (GST, UK VAT, EU VAT) and dynamic QR payment codes. • Client portal & e-signatures: Real-time status tracking so you know when a client views your bill. Live app (free to test, no sign-up required): https://invoicedeck.app Would love honest feedback on the UX or the Terminal template from fellow builders!
🚀 Built a Basic RAG and an Advanced RAG System from Scratch — Without LangChain
To understand how RAG works internally, I first built a Basic RAG Pipeline: Basic RAG PDF → Extraction → Chunking → Embeddings → FAISS Search → Top-K Chunks → Prompt → LLM → Answer It works well for simple questions, but struggles with exact keywords, IDs, and complex queries. So I built an Advanced RAG Pipeline: Advanced RAG PDF → Extraction → Chunking → Embeddings → Dense + Sparse Index → Query Understanding → Dense Retrieval + Sparse Retrieval → Reciprocal Rank Fusion (RRF) → Cross-Encoder Reranking → Noise Filtering → Context Fusion → Prompt → LLM → Answer Key Improvements ✅ Semantic Search (FAISS) ✅ Exact Keyword Search (BM25) ✅ Hybrid Retrieval ✅ Cross-Encoder Reranking ✅ Duplicate Removal ✅ Better Context Selection ✅ Reduced Hallucinations One of the biggest lessons from this project: A better RAG system isn't always about using a better LLM. It's often about building a better retrieval pipeline.

Trust Check BD
Trust Check BD Search before you pay. Report a scam when it happens. Trust Check BD is a community-driven scam reporting and trust verification platform built for Bangladesh. I’m building Trust Check BD to solve a simple but important problem: Before sending money to a person, seller, business, website, or online platform — how can you know whether you can trust them? In Bangladesh, online scams are becoming increasingly common across Facebook, e-commerce platforms, marketplaces, and direct transactions. Many people only discover that someone is a scammer after losing their money . Trust Check BD aims to help people make a more informed decision before they pay . 🚀 What I'm Building Trust Check BD allows users to search and verify digital identities before making a transaction. Users can search for: 📱 Phone numbers 💳 bKash / Nagad numbers 🌐 Websites and domains 📘 Facebook pages 👤 Other digital identities associated with online transactions If a suspicious person or entity has previously been reported, users can discover those reports before sending money. 🔍 Scam Search The core experience is a simple search: Instead of relying on rumors or random Facebook posts, users can find structured scam reports in one centralized platform. 🚨 Scam Reporting Anyone who has experienced an online scam can submit a report with relevant information such as: Scammer identity Phone or payment number Website or social media profile Transaction information Scam description Screenshots or supporting evidence The goal is to turn individual scam experiences into useful information that can protect other people. 🧠 Building a Community-Driven Database Trust Check BD is not just a search tool. I'm building a growing community-driven database of scam reports where information from individual incidents can become useful to thousands of other people. The long-term vision is to make scam-related information easier to discover, understand, and verify before money changes hands. 🛠️ Technology Trust Check BD is built using modern web technologies: Next.js React.js TypeScript Tailwind CSS Node.js Prisma MongoDB PostgreSQL The platform is designed with a focus on: ⚡ Performance 🔎 SEO 📱 Mobile-first experience 🔐 Data integrity 📈 Scalability 🤖 AI-friendly structured content 🎯 Why I'm Building It The idea came from seeing how difficult it can be to determine whether an online seller or individual is trustworthy before making a payment. A simple question inspired the project: "What if people could search someone before sending them money?" That question became Trust Check BD. I'm building it with the goal of creating a reliable digital layer of trust for online transactions in Bangladesh. 🌱 What's Next Trust Check BD is still evolving. Future plans include: Business verification Trusted seller profiles Verified business badges Product and business discovery Better scam intelligence More structured verification data Community-driven trust signals Tools to help businesses build online credibility Ultimately, I want Trust Check BD to become a place where people can check before they trust, search before they pay, and report when something goes wrong. 🔗 Project Website: https://trustcheckbd.com Tagline: Search before you pay, Report a scam when it happens --- 👨💻 Built by Monir Hossain — Full-Stack Developer & Founder I'm building Trust Check BD from idea to production, working across product development, architecture, frontend, backend, database design, SEO, and growth.
I built Trust Check BD after losing 900 BDT to an online scam
In May 2026, I lost 900 BDT to an online scam. The money wasn't the biggest problem. The bigger problem was realizing that before sending money to a seller, there was no simple place where I could search and ask: “Has anyone reported this person or business before?” So I decided to build it. I started Trust Check BD — a free, community-powered platform where people can: → Search phone numbers, bKash/Nagad accounts, websites, Facebook pages, businesses, etc. → See reported scam cases → Submit reports with evidence → Help others avoid similar scams But building it wasn't just about creating a search box. Some of the engineering challenges were interesting: Normalizing Bangla + English search queries Matching different types of identifiers Connecting related reports without uncontrolled database crawling Evidence-based manual moderation Spam and abuse protection Redis caching for repeated searches Localized EN/BN SEO Automatically updating public report pages and sitemap data The most important lesson for me: When you're building a trust product, a false positive can be just as harmful as a missed scam. That's why a submitted report doesn't immediately become a public warning. It goes through validation, evidence collection, and human review first. I documented the full journey—from the original 900 BDT incident to the product architecture, challenges, technology choices, traction, and future roadmap. 👉 Full case study: monirhrabby.com/case-study/trust-check-bd I'm sharing this mainly to document what I learned while building a real product from a very personal problem.
