Daripada 42,281 ulasan, klien menilai SQLite Professionals 4.9 daripada 5 bintang.Hi! I am looking to upgrade my current sales dashboard. I am looking for a Data Specialist who I can learn from and who can propose the best solution for my needs. Data will come from CSV files. I need a place where I can import that data to. I would like the dashboard to be as detailed as possible showing multiple KPIs, graphs, and correlations between the various data. Once setup, I would like it to be fairly simple to import new data, and modify the dashboard as needed over time. I would like this setup to be fully offline and local. My current thoughts are Metabase + SQLite. However I am open to other solutions and recommendations. I will be able to provide an example of the CSV during discussion to see how and what we can achieve with the data. I am looking for an individual who...
I want a lean, dependable Android app that helps me log day-to-day sales without any bells and whistles. The flow is fixed at four material-designed screens: 1. Company creation 2. Product creation 3. Sales / POS entry 4. Report & Export Everything may live in a local SQLite (or similarly lightweight) database so figures stay put between sessions. Jetpack libraries are welcome if they speed things up. Deliverables I expect • Complete Android Studio project with tidy, well-commented code • Signed APK that installs on Android 9+ • Short README describing how to build, where the data sits, and how to trigger the CSV/email export If the compiled APK mirrors the four-step flow above, stores data reliably, and can push out a CSV or email attachment of all rec...
I need an experienced Python trading-bot developer to optimize and refactor a live async trading bot connected to REST & WebSocket APIs, which currently slows under load and misses ticks/orders. The task includes profiling bottlenecks, improving async/WebSocket performance, optimizing pandas & SQLite usage, and ensuring real-time execution. Goal: <200 ms tick-to-order latency, zero missed ticks, clean refactored code, tests, and one-command VPS setup.
I need an end-to-end solution that lets me monitor and, when necessary, remotely control a set of environmental sensors that report temperature, humidity, and air-quality data. Here is the flow I am envisioning: the sensors push readings to the cloud (MQTT, HTTPS, or another lightweight protocol you prefer), the data is stored and processed, and a desktop application then visualises the live feed, keeps historical logs, and lets me define threshold-based actions. Key points I care about • Real-time monitoring and control is the primary goal—latency needs to be kept low and reconnect logic must be solid. • Sensors involved: temperature, humidity, and air quality. The system should be flexible enough to add more sensor types later without a rewrite. • Desktop side...
Saya ingin membangun sebuah aplikasi jejaring sosial Android (APK) yang berfokus pada fitur perpesanan. Versi pertama hanya perlu mendukung pesan teks satu-lawan-satu—cukup stabil, ringan, dan aman.

I need a professional market intelligence tool for MercadoLibre Venezuela (MLV). The goal is to track competitor sales by monitoring inventory changes (Inventory Differential Tracking). Key Features: Discovery Crawler: Identify Item IDs in specific categories. Inventory Tracking: Check stock every 12 hours. Calculate sales: Sales = Stock_{Yesterday} - Stock_{Today} Restock Logic: Handle stock increases without counting them as sales. Anti-Bot: Use rotating proxies to avoid IP bans. Output: Data synced to a Google Sheet.

I need an Android app that lets my field-marketing reps see their entire day laid out on Google Maps, record every turn they take, and automatically total the distance they cover. Each sales call is flagged as a Meeting Point marker so the team can tap it, log arrival and departure time, and have the visit counted in their daily report. Core flow • Reps start a “shift”, the app begins GPS tracking in the background and draws the live route on the map. • Every time they reach a preset Meeting Point, the app recognises the stop, time-stamps it, and asks for a quick note or photo. • When they end the shift, the app stores a summary: full polyline of the route, total distance travelled, list of visited Meeting Points, and idle time between stops. A simple d...
I need a Windows-only desktop application that streamlines how I collect, store, search, and export data. The core focus is reliable data management, so the program must let me create new records, edit them, run quick and advanced searches, and generate simple reports or CSV exports without ever leaving the interface. A clean, intuitive UI is important because I expect non-technical staff to use it daily. Under the hood, I’m open to the stack you feel is most stable—C#/.NET (WinForms or WPF) or a lightweight Electron build are both fine as long as startup time is fast and the installer is straightforward. Local storage can sit in SQLite or a small embedded SQL Server database; just make sure the data file is easy for me to back up. I’ll provide the exact field list and ...
I am building a React Native or Flutter driver application—think Uber’s driver app, but with no payment or passenger-matching logic. The core requirement is a smooth integration with Waze for turn-by-turn navigation, wrapped inside a secure, professional-grade driver experience. The scope in a nutshell • Account & authentication: drivers create a profile that they can unlock via Face ID, password or fingerprint. During first-time setup the Face ID photo must be matched against the photo on the driver’s license (you may rely on any reliable on-device comparison API or a lightweight server call—open to your recommendation). • Daily workflow: once logged in, the driver starts a “shift”, completes a short pre-trip vehicle checklist, licens...
I need a small, self-contained Android application that runs only on my phone—no cloud, no remote server. The goal is to catalogue dancer profiles so I can show, search, and share them quickly during auditions. Core workflow • Create a new profile with name, age, height, full measurements, and the city the dancer is based in. • Attach multiple photos to each profile (photos are the priority), with the option to add a video clip later. • Browse or instantly search by city; that is my main way of organising the list. • From any profile, tap a button to share it straight to WhatsApp or Instagram without exposing the rest of the database. • Keep everything offline in an on-device database (Room or SQLite is fine). A simple “Backup / Restore&rdquo...
Saya ingin membangun aplikasi Android sederhana yang berfokus pada satu fungsi utama: sistem login pengguna yang aman dan lancar. Ruang lingkup: • Desain dan pengembangan front-end serta back-end dasar untuk proses registrasi, autentikasi, dan pemulihan kata sandi. • Antarmuka bersih dan intuitif agar pengguna baru dapat masuk tanpa hambatan. • Penyimpanan data pengguna terenkripsi (Firebase, SQLite, atau solusi setara—saya terbuka pada rekomendasi). Kriteria penerimaan: • APK siap instal dan kode sumber terstruktur. • Dokumentasi singkat cara build dan mengonfigurasi lingkungan. • Semua dependensi dan versi tercantum jelas di README. Jika Anda juga bisa menambahkan opsi seperti pembayaran online atau pemberitahuan push di masa depan, mo...
