I am looking for a telecommunication engineer who could assist in setting up a VoIP app for us. The idea is that we would be able to setup a VoIP app automatically after clients checkout on our website. The client would be sent login credentials to the app and a local number. Need assistance with the best way to set this up and what provider could be used. (Potentially Acrobit Softphone, white label solution). As another example, the calling app should be similar to Viber.

Hi, I’m toying the idea so would love some quotes. Job Title: Build Simple Stud Management App (Horse Breeding) Description: I’m looking for someone to help me turn my horse stud management system into a simple mobile app (iPhone & Android). I currently track things like: • Mare details (name, age, stallion served by, etc.) • Service dates • Scan reminders (14, 30, 45 days) • Foaling due dates • General notes (vet visits, worming, weaning dates, etc.) At the moment I use spreadsheets, but I’d love an easy-to-use app that: • Lets me add/edit mares quickly • Automatically calculates due dates & scan reminders from a service date • Has a calendar view with reminders/notifications • Works offline (important for rural areas with no reception) • Simple, clean design — doesn’t need to be fancy Budget & Scope: • Happy to start with a basic version/MVP (minimal viable product) and build on it later. • Please include examples of similar apps you’ve built. • Ideally, I’d like something I can use myself but with the option to expand in the future. Thankyou, I may look into this marketing this app as well. I have never looked into something like this and unsure of costs, so have only put $100 to put a number in.

Scope (high level): • Fix four UI buttons (colors + spacing/position). • Verify lock/unlock window works as intended. • Verify basket TP/SL closes all and locks until next session. • Fix any small issues stopping clean use on-chart. Deliverables: • .ex4 (compiled EA, ready to drop into MQL4/Experts) • .mq4 source (preferred, but optional) • Works on current MT4 build; no DLLs, no external files. Please include: • Your price & ETA • One example of MT4/MQL4 work We’ll provide the current .mq4 and a screenshot of how the buttons should look. Thanks!

Title: Fix Python App on Google Cloud Run to Send Status Updates to Firestore Description: I have a Python/Flask app running on Google Cloud Run. It performs a multi-step analysis and should update job progress and results to Firestore so the front end can display them. Right now, the process starts but stalls partway and does not reliably send updates. Task requirements: Debug why Firestore updates stop during the workflow. Ensure every step (1–4) reliably writes status and results back to Firestore. Add retries, error handling, and non-blocking logic so Cloud Run does not freeze mid-process. Review and set correct Cloud Run configuration parameters (memory, CPU allocation, timeout, concurrency) to support long-running analysis. Provide tested and working code deployed in Cloud Run. Confirm that status and results are visible in Firestore and accessible to the front end. Tech stack: Python 3.x Flask Google Cloud Run, Firestore, Cloud Storage, frontend Firebase Deliverables: Updated Python codebase with fixes. Verified end-to-end run on Cloud Run with Firestore showing updates at each step. Documented Cloud Run setup (e.g., recommended --cpu, --memory, --timeout, and concurrency settings) so the process is stable. Clear notes on code changes and deployment steps for future maintenance. Experience required: Looking for someone experienced in Python backend development and Google Cloud (Cloud Run, Firestore and Firebase).
