Sitemizi yeni açtık ve müşterilerimize kusursuz bir ilk izlenim yaşatmak için tam zamanlı bir çağrı ve canlı destek ekibine ihtiyacım var.

I want to launch a focused SMS-marketing push that reaches brand-new prospects and drives them straight to my website where my services are sold. I’ll provide the site URL and a brief on the brand voice; you take it from there—building the opt-in list (or integrating with one I obtain), crafting concise, high-converting copy, scheduling the sends, and handling the technical setup through platforms such as Twilio, MessageBird, ClickSend, or any similar gateway you prefer. Key goals • Reach only fresh, untapped audiences—none of my existing customers are to be included. • Keep each message compliant with local regulations (opt-out wording, character limits, sender ID). • Optimise send times and segment by geography or behaviour where possible to maximi...

Title: Manual QA Tester for Voice-AI SaaS Portal (Ongoing, ~10–15 hrs/week) Project: We're building a multi-tenant operator console for a voice-AI agency platform (think: dashboard where small businesses get an AI receptionist that answers their phone, books appointments, and answers questions from a knowledge base). New features ship weekly via AI-assisted development. We need a careful, detail-oriented QA tester to validate every release before it touches real customers. ...
I’m looking for a freelancer who can turn my existing reply guides into an always-on TextBot for WhatsApp. The goal is simple: every customer inquiry must receive an accurate, natural-sounding answer within seconds, and routine questions should be handled automatically so my live team only steps in when truly needed. Here’s what I need you to do: • Design and configure the WhatsApp workflow so the bot greets users, answers FAQs, and, when appropriate, seamlessly hands the conversation to a human. • Build or connect the automation layer (Twilio, WhatsApp Business API, Dialogflow, or any comparable tool you’re comfortable with) to ensure replies go out instantly and logs remain searchable. • Train the response logic with the material I’ll provide&...

I’m building a WhatsApp-based AI assistant whose sole focus is to answer customer queries in a consistently formal tone. The assistant must confidently cover three areas: detailed product information, live order status or tracking updates, and our return / refund policies. The solution has to: • Connect to WhatsApp through an approved API (Twilio, Meta Cloud API or a comparable gateway). • Pull real-time data from my existing product catalogue and order-management system so replies stay accurate. • Recognise when a question sits outside those three topics and hand the chat to a human agent. • Maintain a formal writing style in every generated response. Deliverables: 1. Fully documented source code or low-code workflow for the conversational logic a...
I need an experienced Project Manager who can take full ownership of an upcoming SMS-based automation build.

I want my WhatsApp business line to answer incoming messages automatically so customers receive an immediate, helpful reply no matter when they write. The flow should recognise keywords, pull the correct template, and return a natural-sounding message in seconds, without any manual intervention from my side. Scope • Design and implement a WhatsApp TextBot focused exclusively on automated responses. • Build a simple dashboard or configuration file so I can edit reply text and keywords on my own. • Make sure the solution respects WhatsApp Business API policies and delivers responses reliably 24/7. Technical notes I do not have an existing bot, so you may suggest the best route—Twilio, Meta Cloud API, or a comparable tool—as long as the final setup runs smooth...
I need my existing WhatsApp number turned into a mini-call center dedicated to handling sales inquiries. Agents must be able to switch seamlessly between text chats and voice calls inside WhatsApp, so the chosen solution should support both modalities without forcing customers to change apps. • Core requirements A multi-agent system that intelligently routes incoming sales inquiries—whether messages or calls—to the next available representative. Once a customer is initially handled by a specific representative, all subsequent interactions are automatically assigned to the same representative to ensure continuity and a personalized customer experience • Smart automated responses that greet prospects instantly, capture basic information, and keep them engaged until...
I need a SIP trunk sourced from the United States that comes with at least one DID number, delivers rock-solid reliability, and offers self-service access on par with Twilio (API, online dashboard, real-time monitoring, etc.). The trunk will carry both local and international traffic, so consistent call quality and proven carrier routes are non-negotiable. My existing setup runs through a PBX system. Your job is to help me choose or broker the right carrier, secure the numbers, and complete the technical cut-over so calls flow seamlessly through the PBX without service disruption. Key expectations • 100 % uptime or SLA that truly rivals Twilio • Full documentation of trunk credentials, SIP endpoints, and API details • End-to-end testing—originating and termin...
