    If you do it from the beginning according to SOLID principles, it's a year-long task; rushing leads to security issues. I am willing to take on this task, but the cost is an invoice every month, of course for progress. Daily call. I have mainly worked on such large projects.

    Hi! I can implement this project with the following technology stack:
    Backend: Node.js (Nest.js or Express) with PostgreSQL/MySQL for data storage, and Redis for caching and job queues.

    Hi there!

    This project has a wide scope and it is clear that the first phase will lay the foundation for a very powerful system. I can build the user management with two roles in a secure web interface where admins have full control and agents get only what they need for their daily work. Lead management will be smooth with imports from CSV, Excel, or external APIs, and the system will validate the data so every list stays clean and ready to use. Admins will be able to assign lists, track statuses automatically, and search or filter contacts quickly.

    The dialer is a central part and I can make sure it handles multiple outbound lines with predictive dialing, accurate answer detection, and line rotation so call quality stays high. The agent interface will show clear information like maps and external links, plus simple tools for notes, scripts, voicemail drops, and call recordings. For admins, I will design dashboards that track performance, connect rates, and campaign results in a way that is easy to read but rich in detail.

    One special idea I can bring here is to combine AI generated summaries with sentiment scoring so that after each call, managers and agents get instant insights without needing to replay recordings. This will save hours and also highlight hidden patterns in customer responses. Along with this, the system will monitor spam risks in real time, rotate numbers automatically, and keep compliance in check.

    I will prepare the code in a modular way so integrations with Twilio, Salesforce, HubSpot, or Zapier can be added without friction. Every feature will come documented and ready for scaling as the project grows.

    Thank you!

    Good day! My name is Dmytro, and I represent the Averix agency.

    We specialize in developing complex SaaS systems, call centers, CRMs, and integrations with telephony. Your project looks like a large-scale idea with great potential, and these are exactly the kinds of tasks we love to take on.

    Why us:

    Experience: we have expertise in developing VOIP/telephony solutions based on Twilio, integrations with CRMs (HubSpot, Salesforce), and automation through Zapier/Webhooks.

    Architecture: we always build the system to be scalable — from MVP to production level with thousands of leads and agents.

    Team: it’s not just one developer working, but a team (frontend, backend, AI/ML, and DevOps), which allows us to tackle all tasks in parallel and quickly.

    Security and compliance: we are familiar with FCC/TCPA and the mandatory STIR/SHAKEN standards, which are critically important for telephony.

    AI approach: we can implement predictive dialing, auto-responder detection, call optimization, and even AI-based scenarios.

    Our approach to your project:

    We will start with an MVP that includes user management, lead import/assignment, and a basic agent interface with automated dialing.

    Next, we will integrate Twilio telephony with support for multi-channel dialing and features like call recording, notes, and reporting.

    In the next phase — AI and analytics, to optimize the process and give your system a competitive edge.

    We are ready to fully take on the development from scratch or connect to an existing project.

    I would be happy to discuss the details of your idea, show our cases, and propose a roadmap for implementation.

    Best regards,
    Dmytro
    Representative of Averix agency

    Hi Snezhana,
    Thanks for sharing such a clear and detailed project outline. To better understand your priorities and ensure we build the right foundation, I’d like to clarify a few points:

    1. Do you want all listed features in the initial release, or should we focus on a smaller MVP first (e.g., lead import, basic dialer, dashboards)?

    2. Do you already have UI/UX mockups, or should the design be created from scratch?

    3. What is the expected scale for the first phase (number of agents, concurrent calls, lead volume)?

    4. Should the system be cloud-hosted (AWS/GCP/Azure) or on-premises? Do you require high availability or call/data backups?

    5. Which regions/countries should compliance cover (e.g., FCC/TCPA in the US, GDPR in the EU)?

    6. For the AI features (predictive dialing, call summaries, spam detection), do you expect full implementation right away or a phased/placeholder approach at first?

    7. Is Twilio the mandatory telephony provider, or should we keep the option open for alternatives?

    8. For CRM integrations (Salesforce, HubSpot, Zapier), are there specific platforms you need supported in phase one?

    9. Are there defined timelines and budget constraints we should keep in mind?

    10. Do you envision only Admin and Agent roles, or should we also plan for Supervisor/QA roles later on?

    Looking forward to your feedback so we can align on the roadmap!
