🚀 Excited to share my latest project: A Full-Stack Inventory Management System! Managing inventory isn’t just about storing data—it’s about predicting demand, preventing stockouts, and scaling with confidence. That’s exactly what I focused on while building this system from scratch using Python & Flask. This isn’t a typical CRUD app. I implemented a custom demand simulation engine to stress-test inventory behavior under real-world scenarios like demand spikes and stock fluctuations. 🔧 Key Technical Highlights 🔹 Backend: Python (Flask), SQLite, SQLAlchemy 🔹 Frontend: Jinja2, Bootstrap 5, Vanilla JavaScript 🔹 Architecture: Modular Flask Blueprints for clean scalability 🔹 Simulation Engine: Real-time demand forecasting & stock movement analytics 📊 The system provides live inventory insights, helping simulate decision-making before real losses occur. 🎥 Check out the demo video below to see real-time analytics in action! #Python #Flask #FullStackDevelopment #InventoryManagement #SoftwareEngineering #WebDevelopment #Backend #Projects

🚀 A URL Shortener web application built using Python and Flask! This project lets users convert long URLs into short, shareable links while keeping track of their URL history. It showcases key backend skills like URL validation, Base62 encoding, Flask routing, and database management with SQLite and SQLAlchemy. The clean, responsive UI is built with Bootstrap for an easy user experience. Key Features: Validates URLs before shortening Generates short URLs using Base62 encoding Tracks and displays URL history Responsive and clean UI A big thank you to Innomatics Research Labs for their invaluable guidance and support throughout the development of this project! 🙏 This project was a great learning experience, reinforcing core web development concepts and backend programming. Looking forward to building more exciting projects! #Python #Flask #URLShortener #Coding #Projects

🚀 Building a URL Shortener with Flask & SQLAlchemy In this project, I built a simple yet powerful URL shortener web app using Flask, SQLite, and SQLAlchemy. 🔑 Key highlights: User authentication with registration & login URL shortening with unique short codes Dashboard to manage your own links Fixed common pitfalls like “Working outside of application context” and missing columns in SQLite by properly setting up the database schema with app.app_context() and migrations. 💡 This project taught me how important it is to align model definitions with the actual database schema, and how to handle application context in Flask correctly. 👉 Check out the video to see the app in action — from login to shortening links and redirecting seamlessly!

🚀 Project Spotlight: Real-Time Weather App with Flask & OpenWeatherMap API 🌤️ Excited to share a small project I recently built! Using Python Flask, I developed a web app that lets users check the current weather of any city in real-time. Key Features: Fetches city coordinates using OpenWeatherMap Geo API. Retrieves current temperature, humidity, wind speed, and weather description. User-friendly web interface for easy city input. Robust handling of invalid city names or network errors. This project was a great way to combine backend development with API integration, and it gave me hands-on experience with real-time data fetching and web deployment. 💡 Tech Stack: • Python 3.x • Flask • OpenWeatherMap API • HTML/CSS for frontend Check out the demo below! I’d love to hear your thoughts and any suggestions for improvements! #Python #Flask #WebDevelopment #API #OpenWeatherMap #WeatherApp #ProjectShowcase #Coding

I Built a Search Engine from Scratch 🔍 I wanted to know exactly how Google handles billions of pages. So, I built a custom search engine from scratch using Python. What’s inside: ✅ Custom Crawler: Asynchronous web navigation and data extraction. ✅ Inverted Index: Optimized data structures for sub-second document retrieval. ✅ Query Engine: Smart ranking logic to deliver relevant results. ✅ Interface: A clean, functional interface for real-time searching. The Workflow: ✅Performance: Managed dependencies with uv for a lightning-fast dev environment. ✅Reliability: Integrated GitHub Actions for automated CI and code formatting. Key takeaway: Building the fundamentals manually is the best way to understand complex systems. Tools used: Python, BeautifulSoup, uv, Flask, GitHub Actions. Please do check it out and let me know what you think! Git Repo: https://lnkd.in/ggERQ95Z #SearchEngine #PythonDeveloper #SoftwareDeveloper

Bridging Flutter & Flask: Building a Full-Stack Regex Engine I’m thrilled to share my latest project—a Regex Matching Web App that combines a sleek Flutter UI with a powerful Flask backend. Inspired by Regex101, this project was a deep dive into building a seamless communication bridge between a cross-platform frontend and Python’s robust logic. 🛠️ The Tech Stack: Frontend (Flutter): Crafted a responsive, intuitive UI to handle user inputs and display matches dynamically. Backend (Flask): Built a RESTful logic layer to process regular expressions using Python’s re module. The Bridge: Managed the data flow between the two to ensure real-time feedback and instant pattern validation. Key Features: 🔹 Dynamic match highlighting 🔹 Robust error handling for invalid regex patterns 🔹 Clean, modular architecture Special thanks to Innomatics Research Labs for the guidance and the opportunity to sharpen my full-stack skills! github link -> https://lnkd.in/gQ7fpggM #FullStack #Flutter #Flask #Python #WebDevelopment #Regex #InnomaticsResearchLabs

I recently completed a URL Shortener web application using Django, and this video shows the project in action 🎥 What this project does: Converts long URLs into short, unique links using Base62 encoding Allows short links to be opened directly from any browser Redirects users to the original website seamlessly Tracks how many times each short link is visited Includes user authentication so links are user-specific Deployed using Gunicorn and Whitenoise Live demo: https://lnkd.in/ggquvJ5r Repo: https://lnkd.in/g-7XwVyM 📌 Tech used: Python | Django | SQLite | Gunicorn | Whitenoise Feedback and suggestions are welcome — especially around scaling, security, or analytics improvements. #DjangoProject #PythonDeveloper #BackendDevelopment #WebApp #LearningByDoing #StudentDeveloper #BuildInPublic

So, Uvicorn is the way to go. Fast, that's what it is. It's like a sports car for your Python code - gets the job done quickly. You can install it with pip, easy peasy: just type in pip install uvicorn and you're good to go. Now, let's get to the fun part. Creating a simple example is a breeze. First, create a file named main.py - don't overthink it, just a basic file. Then, add this code: you'll need an async function, let's call it app, that takes in scope, receive, and send. It's like a little messenger, sending and receiving info. So, you'll have something like async def app(scope, receive, send): - pretty straightforward. Next, you'll want to send a response, like a hello message - await send({'type': 'http.response.start', 'status': 200, 'headers': [[b'content-type', b'text/plain']]}) does the trick. And finally, you'll send the actual message: await send({'type': 'http.response.body', 'body': b'Hello, Dev.to!'}) - simple, right? Run it with uvicorn main:app --reload, and you're off. It's fast, really fast. Thousands of connections at the same time? No problem. But, you know, there are other options out there - like Hypercorn for HTTP/3 support, or Daphne for Django Channels. And if you want even more speed, Granian's your guy. Just remember, offload those blocking tasks, or your Uvicorn loop will be slow. Use run_in_executor for blocking code, and you'll be golden. If you're building a modern Python web app, Uvicorn's a great choice - it's all about balance, ease of use, and speed. Innovation, creativity, and strategy all come into play here.
