    Technical Review of Django/Python SaaS Platform
    6 дні(-в) left
    Верифіковано

    About the project We are building, a legal practice management platform designed specifically for small UK law firms. The product has been founder-built and has now developed into a substantial application. It is already well beyond prototype stage, but it has reached the point where I want an experienced senior engineer to review the architecture, challenge previous decisions, identify technical risks and help establish a maintainable engineering direction. This is not a greenfield project and I am not looking for someone to rewrite the application from scratch. I am looking for someone who is particularly good at inheriting existing systems, understanding them quickly and deciding what should be kept, simplified, improved, removed or deferred. Current technology The application is ...

    Financial Literacy & Lead-Generation App — Project Description Overview We are building a mobile-friendly application for a bank that helps everyday users understand insurance products and other financial instruments (savings, investment, and protection products) in a simple, friendly, and multilingual way. The app is educational and lead-focused: users learn about products, get their questions answered by an AI assistant, and can submit an enquiry that is routed to the bank's sales/agent team for follow-up. This is a non-transactional platform — no purchases, payments, or account opening in this phase. Goal Improve financial literacy, present the bank's products in an accessible format, and generate qualified leads — while giving the bank full control to ...

I need a working, fully-verified Plivo account plus the email inbox that is tied to it, so I can manage both credentials myself. What I tried: I already attempted registering with a non-Gmail address and Plivo still denied the signup, so the usual work-arounds are exhausted on my side. Here’s what I need from you: • Create a brand-new Plivo account that passes Plivo’s phone/SMS and email verification steps. • Register it with an email service that reliably receives Plivo messages (any reputable provider is fine as long as it works). • Hand over the login credentials for both Plivo and the new emai...
