SQLite Jobs

Project Overview I am looking for an experienced Delphi and SQLite developer to customize an existing software called RP Gerador Financeiro. The software is already working and currently generates payment receipts. I do not want a new system created from scratch. I need modifications made directly to the existing software and database. Current Environment Software: RP Gerador Financeiro Database: SQLite (.db3) Existing tables: CLIENTES RECIBOS EMPRESA RECEBER Approximately 35 active students Individual English lessons Monthly receipts Main Requirements 1. Student Database Integration The software already contains a CLIENTES table. I want all 35 students registered in the database and available directly inside the receipt generation screen. The system should allow: Selecting a studen...

## 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 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...

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...

I already mapped every screen and interaction in a Figma file; now I need a skilled Android developer to bring that design to life as an offline-first billing application. Core scope • Invoice generation – users must be able to create, edit, preview, and share invoices even with no internet connection. PDF export and sequential invoice numbers are part of the flow. • Customer management – add, search, update, and view a customer’s past invoices locally. Because the app must work reliably without connectivity, please plan on a lightweight local database (Room/SQLite or a comparable approach), careful state handling, and background sync hooks so I can later add cloud backup if I choose. I will provide: • Complete Figma design and UX specs. • F...
