Project: Multi-User SMS Alarm Forwarding System to WhatsApp & Telegram Overview I am looking for a developer to build a multi-user system where each user (company) can receive SMS alerts from a source and automatically forward these alerts to WhatsApp and Telegram. This is for operational alerting, not marketing or spam. Core Concept (Important) • Each user = one company • Each company has: • Its own assigned SMS number (for receiving logger alerts) • Its own forwarding configuration • Messages received for one company must only be forwarded based on that company’s settings Background My client uses a system which generate alarm alerts. These devices can only send alerts to a single SMS number. The system should: • Receive SMS from the assigned number • Identify which company the number belongs to • Forward the message according to that company’s configuration Scope of Work 1. Multi-User System • Admin can create multiple users (companies) • Each user has: • Company name • Assigned SMS number • Separate forwarding settings 2. SMS Receiving • System must receive incoming SMS via gateway/API • Each SMS is linked to the correct user/company 3. Auto Forwarding (Per User) • When SMS is received, system automatically forwards to configured destinations: • WhatsApp number(s) • WhatsApp group(s) • Telegram number/group(s) 4. User Dashboard (Per Company) Each user can: • Login securely • Configure forwarding destinations: • Add/remove WhatsApp numbers or groups • Add/remove Telegram destinations 5. Admin Panel • Create/manage users • Assign SMS numbers to users • Monitor system usage 6. Logging • Store: • Incoming SMS • Timestamp • User/company • Forwarding results (success/failure) Hosting & Handover Requirements • Developer must: • Deploy and host the system online (cloud-based) • Ensure system is fully working and accessible • Handover full ownership to me, including: • Complete source code • Deployment setup • Documentation (basic setup & maintenance guide) Technical Architecture Hint (Important) Expected flow: • SMS received via gateway (e.g. Twilio or equivalent) • Gateway triggers webhook → backend server • Backend identifies user/company based on receiving number • Store message in database • Forward message to: • Telegram via Bot API • WhatsApp via API or controlled automation Suggested stack (flexible): • Backend: Node.js / Python • Database: PostgreSQL / Firebase • Hosting: AWS / Vercel / Render Developer must clearly explain: • How multi-user mapping is handled • How WhatsApp integration is implemented (API vs automation) • How system ensures reliability Timeline • Prefer fast delivery

Hello, I understand you need a multi-user SMS alert forwarding system where each company independently receives alerts via a unique SMS number and forwards them automatically to WhatsApp and Telegram based on their specific settings. I will develop a secure, cloud-hosted platform allowing admin control to manage users and their SMS numbers, and users can customize their forwarding options easily via a dashboard. The system will reliably receive SMS through a gateway, map messages to the correct company, store logs, and forward alerts promptly using the Telegram Bot API and WhatsApp API or controlled automation. I will provide clear documentation and handover the full source code with deployment instructions. Could you confirm which SMS gateway you prefer for SMS reception? Which SMS gateway do you currently use or want to use for receiving SMS messages? Best regards,

Hi there, We’ve built similar multi-user systems that receive SMS and forward them to WhatsApp and Telegram, ensuring each user’s data remains private and secure. We’ve integrated with Twilio and other SMS gateways, so we know how to handle incoming messages and link them to the right user. For this project, we can use a dedicated SMS number for each user or a shared number that forwards messages based on the original sender’s number. We can also implement a feature to send messages from WhatsApp and Telegram back to the original SMS sender, if needed. Let’s schedule a 10-minute call to discuss your requirements in more detail and see if I’m the right fit for your project. I’m eager to learn more about your exciting project. Best, Adil

I'm Iosif Peterfi, 15+ years delivering robust web systems across Europe. This is my speciality: building secure, multi-tenant alert routing that maps each incoming SMS to the right company and forwards to WhatsApp and Telegram with clear audit trails and reliable delivery. You need a multi-user system where each company has its own assigned SMS number and separate forwarding settings, with automatic routing of logger alerts to WhatsApp and Telegram. The solution must support per-company dashboards, an admin panel to manage users and numbers, hosting in the cloud, and a complete handover with source, deployment steps, and maintenance guidance. The goal is accurate mapping, predictable delivery, and a clear activity log, without cross-tenant data leakage. I'll deliver a secure, scalable backend with strict multi-tenant isolation and per-user configurations. The system will receive SMS via a gateway, determine the company by the receiving number, store the message with a timestamp, and forward to configured WhatsApp numbers, groups, and Telegram destinations. Each company gets a dedicated dashboard to adjust destinations, while admins manage users and assigned numbers. We'll implement reliable delivery with retry and visible success/failure logs, plus lightweight monitoring. Hosting will be cloud-based, with a straightforward handover and concise setup/docs.

I understand you need a multi-user system that receives SMS alerts per company and forwards them reliably to WhatsApp and Telegram based on each company’s settings. From experience, mapping each SMS number to a company in the backend is straightforward by storing unique SMS numbers per user in a database. The webhook triggered by the SMS gateway (e.g., Twilio) feeds the message to the backend, which looks up the company and stores the alert before forwarding. For WhatsApp integration, using the WhatsApp Business API is stable but requires approval; alternatively, controlled automation tools like Puppeteer can work if API isn’t available. Telegram forwarding via Bot API is simple and reliable. To ensure delivery reliability, I suggest implementing retry logic on failed forwards and logging all outgoing attempts with timestamps and results. A clean user dashboard for forwarding config and an admin panel for user management will complete the flow as you outlined. Do you have a preferred SMS gateway, or would you want me to recommend one based on pricing and reliability? Also, is using WhatsApp Business API feasible on your end, or would automation be better? Ready to start building and deploy the system quickly with a clear handover.

You need a multi-tenant SMS->WhatsApp/Telegram forwarder where each company owns an SMS number, its own forwarding rules, and strict message isolation. Scope: webhook receiver for incoming SMS, map the SMS "to" number to a company, persist the message, enqueue forwarding per-company, provide per-company dashboard and an admin panel, and deliver deployment plus full handover. Sharp insight: WhatsApp is the real constraint. The reliable, supported path is WhatsApp Business API (via Meta partners or Twilio’s WhatsApp channel). Browser automation (Puppeteer/WhatsApp Web) works for PoC but introduces reliability, scaling, and TOS risk — worth deciding up-front. Proof: experience working with SMS gateway webhooks and Telegram Bot API integrations (conversation-ready code and architecture notes available on request). Approach: Node.js backend, PostgreSQL for company↔number mapping, webhook endpoint that resolves company by receiving number, store message, push to a forwarding queue with retry/backoff and per-destination delivery logs; use Telegram Bot API for Telegram, WhatsApp Business API (or Twilio WhatsApp) for WhatsApp; admin + company dashboards, logging, and full deployment on AWS/Render with documentation and source handed over. Answers: - Multi-user mapping: canonical lookup on "to" number indexed in DB; immutable assignment enforced in admin. - WhatsApp integration: recommend WhatsApp Business API via Twilio/Meta; fallback automation only for PoC. - Reliability: durable queue, idempotent forwarding, per-destination retries, and delivery status logging. Do you already have WhatsApp Business API access or should I include provisioning options (Twilio vs direct Meta partner) in the proposal?

We can build this as a secure multi-tenant alerting platform where each company is mapped to its own receiving number, forwarding rules, and delivery logs, so messages never cross between users. I’ll structure the backend around SMS webhooks, per-company routing, database-backed audit trails, and an admin/user dashboard for managing destinations and monitoring delivery status. For WhatsApp, we’ll clearly define the integration approach up front: API-based delivery where available, with a controlled fallback only if your policy and reliability requirements allow it. We’ll also deploy the system online, provide the source code and setup documentation, and ensure ownership is fully transferred with a maintainable handover.

Operational alerting systems need to be reliable above everything else. A missed alarm is not a minor bug, it is a business problem for your client's customers. That reliability requirement is what makes this project more involved than it looks on the surface. I would build this on Node.js with PostgreSQL for the backend, Twilio for SMS receiving and WhatsApp forwarding, and the Telegram Bot API for Telegram delivery. Each incoming SMS hits a webhook, gets matched to the correct company via the receiving number, stored in the database with a timestamp, then forwarded to that company's configured destinations with success and failure logged for every attempt. On WhatsApp specifically: the official WhatsApp Business API through Twilio is the compliant and reliable path here. I want to flag upfront that there are per-message costs on Twilio's end that you should factor into your ongoing operational budget. I will provide a cost breakdown before we start. The multi-user dashboard and admin panel would be a clean web interface where each company logs in, manages their forwarding destinations, and sees their message history. Delivery in 7 days including deployment, source code handover, and documentation. My bid is $600. Happy to jump on a quick call to walk through the architecture before you decide.
