SQLite Jobs

Project Title: OEE Monitoring System Development (ESP32 + Node-RED + Orange Pi + MQTT + SQLite) --- Project Description: I am looking for an experienced developer to build and complete an industrial OEE (Overall Equipment Effectiveness) monitoring system based on my existing architecture. The system is already partially designed, and the web dashboard is already available. The main task is to complete the data acquisition, processing, and integration layers. This is an edge-based industrial system, not a simple web app. --- System Architecture Overview: Machine → ESP32 → Orange Pi → Node-RED → MQTT → Dashboard ↓ SQLite (historical data) ↓ Firebase (cloud sync) --- Scope of Work: 1. ESP32 Development - Read machine data via: - Digital inputs ...

I need an Android application (translated to spanish) built that lets me keep a precise, day-by-day record of how much lysine, protein, and calories I consume. Every time I eat, I want to type the food name, quantity, and time; the app must immediately calculate the three nutrients and add the entry to the current day’s log. All food data—including lysine content—has to live in a fully editable database inside the app. I should be able to add, adjust, or delete any food and its “per-100 g” numbers without ever leaving the interface. For the records themselves, everything must be stored locally (SQLite / Room, or any robust on-device option). When I open the app I expect a clean graphical overview of today’s totals and an easy way to swipe back throug...

I already have a Flutter-based mobile POS app and need to add true offline capability so staff can keep working without connectivity and then push everything safely to the cloud. Key requirements • Data to cache and sync: sales transactions, inventory updates, and customer information. • Sync cadence: an automatic periodic job—about once an hour—that wakes up, checks connectivity, and pushes/pulls changes. • Conflict strategy: when the cloud copy disagrees with what was captured offline, the local changes win automatically. What I expect from you 1. Choose or implement an efficient local persistence layer (e.g., SQLite, Hive, or similar) and wire it into my existing Flutter codebase. 2. Build a lightweight queue/change-tracking mechanism so new or...

I manage both Indian wedding shoots and post-production for American clients, so dozens of events, photographers, editors, invoices, and deadlines move through my hands at once. At the moment everything lives in a sprawling Excel file that my manager updates, but scrolling through rows is slowing us down. I want that spreadsheet converted into a clean, purpose-built desktop application that runs natively on Windows and Mac. What the app must do • Create a job card with client details, shoot date, assigned team members, and promised delivery date. • Let us update team status in real time—who’s shooting, who’s editing, who’s designing albums—so I can see bottlenecks at a glance. • Track every deliverable (footage, edited photos, highlight f...

Proyek ini berfokus pada pengembangan sebuah aplikasi Android bertema pendidikan. Aplikasi perlu berjalan mulus di perangkat Android modern, mematuhi pedoman Material Design, dan memuat fitur inti pengajaran–misalnya modul pelajaran, kuis interaktif, serta pelacakan kemajuan pengguna. Ruang lingkup kerja: • Merancang arsitektur aplikasi yang bersih (MVVM atau serupa) dengan Kotlin. • Membangun antarmuka ramah pengguna yang responsif. • Menghubungkan data lokal (Room/SQLite) dan, bila perlu, endpoint cloud sederhana untuk sinkronisasi. • Menyediakan dokumentasi singkat cara build serta file APK siap rilis. Kriteria keberhasilan: • Aplikasi dapat di-install tanpa crash pada Android 8+. • Semua fungsi inti (buka pelajaran, kerjakan kuis, simpan sk...

I already run this multi-layer intraday trend-and-momentum strategy live on TradingView, and it behaves exactly as intended there. Now I need the same logic translated to a Python algo that talks to Zerodha’s Kite API so it can place and manage real NSE/BSE orders automatically. All of the trading logic is ready in Pine Script: dual-timeframe directional scoring, twin SuperTrend confirmation, jump/flip pattern triggers, momentum state scoring, ATR-managed exits, dynamic stop-losses, a trend filter, and strict intraday time gating. The job here is to reproduce that behaviour faithfully in Python, keep it modular for easy parameter tweaks, and wire it for live execution. I want you to build on familiar tools—Pandas for data handling, TA-Lib for indicator parity, and Backtrader ...

Devo realizzare un software di gestione dati sviluppato in Java. Il programma dovrà permettere di archiviare, modificare, filtrare e generare report dalle informazioni inserite dall’utente tramite un’interfaccia desktop semplice e intuitiva. In sintesi mi occorre: • Analisi rapida dei requisiti con me per definire le entità principali e le relazioni fra i dati. • Progettazione di un piccolo database locale (può andare bene H2 o SQLite) con le tabelle essenziali. • Implementazione in Java (preferisco Java 17 o superiore) con Swing, JavaFX o altra libreria UI a tua scelta, purché resti cross-platform. • Funzioni CRUD complete, ricerca avanzata e esportazione in CSV o Excel. • Consegna del codice sorgente ben commentato...

Saya mencari mitra pengembang untuk membangun sebuah aplikasi seluler berbasis Android dengan fokus utama pada fungsi media sosial. Saya sudah mantap memilih jalur Aplikasi Seluler dan menargetkan rilis khusus di Android terlebih dahulu. Ruang lingkup awal yang saya butuhkan mencakup: • Penyusunan arsitektur dan database dasar yang mendukung interaksi pengguna secara real-time. • Desain antarmuka yang modern serta ramah pengguna, lengkap dengan skema warna dan ikon yang konsisten. • Implementasi fitur inti media sosial—akun pengguna, unggah konten, komentar, dan notifikasi. • Integrasi API pihak ketiga seperlunya (mis. autentikasi, penyimpanan cloud, atau analitik). • Pengujian fungsional dan dokumentasi singkat agar aplikasi mudah dipelihara dan...

Project Overview: I am looking for a developer or team to build a dual-mode educational grading system. The system consists of: An iOS App: Capable of real-time scanning and grading of both standard OMR bubble sheets AND unique orientation-based cards (Plickers-style). A PHP Web Backend: A tool to generate customized PDF test sheets and student cards using Chromium (via Spatie/Browsershot). Privacy is paramount. All student scanning and grading must occur on-device to ensure data security. Module 1: The iOS App (Swift/SwiftUI) The app must feature a toggle or auto-detection to switch between two modes: Mode A: OMR Bubble Sheets: Detects standard multiple-choice grids. Real-time detection of "filled" vs. "empty" bubbles using local image thresholding. Mode B: Pli...
