I have started a roster of PKL participants along with the kind of transport they use—motorbike or public transportation—but it is incomplete. I need you to turn it into a neatly ordered, fully populated text file (.txt, UTF-8). Each entry must follow this structure: Name | Transport Type | Address You may stage the data in SQLite while working; that is the database format I am most comfortable reviewing should I ever need to expand or import the list later. However, the final hand-off must still be a plain text file. What you will do: • Use the twelve names I have already given as the starting point. • Fill in any missing numbering, fix obvious typos, and keep the transport notes exactly as stated (Motorcycle, GL Motorcycle, etc.). • Research or req...
I need a compact Windows desktop application that pulls equity and derivative market data every minute from the APIs I currently rely on—Dhan, Fyers and Zerodha—while leaving room to drop in Truedata or any other reliable feed later. The program must: • Stream and store both real-time ticks and end-of-day OHLCVOI in a local database (SQLite or PostgreSQL, whichever you recommend for speed and stability). • Expose the stored data through a lightweight interface my existing Python-based algo engine can query with minimal latency. • Simultaneously push the live stream to a separate Python charting module so I can view candles forming in real time. • After the closing bell, run an automated reconciliation that compares OHLCVOI from at least three sources ...

I need an Android-only app that stops the endless scroll on Facebook, Instagram and TikTok, while giving users a live view of exactly how long they spend on each of those platforms. The core idea is simple: whenever the user activates Focus Mode inside the app, vertical scrolling, shorts, reels or any other auto-play feed in the three selected social media apps must be completely blocked until the timer ends or the user explicitly unlocks it with a PIN. Real-time tracking is essential. The moment any of the three apps comes to the foreground, a counter should start and update on a small overlay or notification, then roll straight into a dashboard that shows current session length, total time today and historical charts. No scheduled daily or weekly batches—everything updates instant...
## Project Description Develop a secure cross-device synchronization system for an existing React web application and React Native mobile application. The applications store machine-learning generated data locally, including face embeddings, vector embeddings, media metadata, and versioning information using IndexedDB (Web) and SQLite (Mobile). The objective is to enable automatic synchronization of data between a user's authorized devices while minimizing network usage and avoiding full database transfers. The solution should support Web-to-Mobile, Mobile-to-Web, and Mobile-to-Mobile synchronization through efficient device discovery and bi-directional data exchange within the LAN/Wifi network. The synchronization process must transfer only new or updated records, prevent duplicat...

I’m looking to have a small, focused web project built that lets users create and edit their own playlists directly in-browser. The core of the job is straightforward website development rather than a full-scale app: a clean interface where tracks can be added, reordered, renamed, or removed, with changes stored instantly. Here’s what I need accomplished: • A lightweight front-end (plain HTML/CSS/JavaScript or a modern framework if you prefer) showing the playlist and its controls. • Simple back-end logic to persist the playlist data—SQLite, Firebase, or any equally uncomplicated solution is fine as long as it keeps the project easy to deploy. • Basic user flow: open the page, see the current playlist, click to add a new item (title + optional link), d...
