Title: Full-Stack Code Audit — Web Platform + iOS/Android Apps (Post-Handover Review)

Overview
We operate a live web platform (cpanel.ssfservices.com.au) with companion iOS and Android apps. The sole developer who built and maintained the entire stack has departed. We need an independent full-stack developer to review the codebase and tell us exactly what we have inherited before new work begins.
This is an assessment engagement, not feature development.

Follow-on maintenance work is possible for the right candidate.
Scope
∙ Backend/API: architecture, code quality, framework and dependency versions, end-of-life risk
∙ Database: schema design, integrity, indexing, migration history
∙ Frontend/admin panel: structure, maintainability, dead code
∙ Mobile apps (iOS + Android): build viability from source, signing/credential status, store deployment readiness
∙ Infrastructure: hosting, deployment process, environment configuration, backups
∙ Security: authentication, authorisation, secrets handling, exposed endpoints, OWASP Top 10 pass
∙ Documentation and handover completeness: what is missing for a new developer to take over cleanly
∙ Bus-factor and key-person risk: undocumented logic, hardcoded values, external service dependencies
Deliverables
1. Written audit report with findings ranked Critical / High / Medium / Low, each with location, impact, and remediation estimate
2. Effort and cost estimate to bring the codebase to a maintainable baseline
3. Verdict: maintain and refactor, partial rewrite, or full rebuild — with reasoning
4. Gap list of anything still required from the previous developer
5. 60-minute walkthrough call
Requirements
∙ 5+ years full-stack, with demonstrated audit or takeover-of-legacy-codebase experience
∙ Proven capability across backend, database, and both mobile platforms
∙ Ability to read and assess unfamiliar code without extensive hand-holding

Willing to sign an NDA before repository access

Essentially trying to create a watch that looks similar to a fitbit. Sleek and stylish looking watch, but with far less components/ abilities and to be used for a specific purpose.

I want a watch that can easily obtain notifications from a phone app that can ping it everytime it needs something. Then a certain box/ boxes displayed on the watch will either light up or blink.

This product is essentially like a notification tool. Wanting a manufacturer that has experience in executing on a product such as this, with a high level of quality. Needing the designer/ engineering team in order to design if needed and to put this product together.

RAG agent and deployment int0 a high;y nuanced ecommerce platform

Hi everyone,

We are looking for a freelance or a company to build a B2C mobile app + B2B desktop app/software for our project.

The mobile application is intended to support people to manage their life. The software is intended to support companies to manage their organization, such as a enterprise management tool.

GOAL
- We expect to deliver an MVP by end of the year/beginning next year, with 1k B2C users for the mobile app and up to 50 B2B customers in the following 3/6 months

IMPORTANT NOTES:

- The IP of this project will be entirely transferred as final output of the project, without any restriction or limitation. The project is supposed to be the MVP for a new startup, so we can't allow any kind of restriction or limitation of the IP, after the project is fully paid. This includes: Transferring the IP property to third party, selling the product, selling the project code, allow a third party vendor to distribute and sell our product.

- The team/freelancer will work on our own repository

- A NDA is supposed to be signed before the full requirements, design and scope are entirely shared

- English is required as international people will be involved on the project

- The database and the cloud infrastructure must be configured as part of the scope of the project - the cost of the infrastructure is up to us. posgreSQL could be a good candidate for the project MVP.

- The mobile app should be develop for both Android and iOS - We expect Flutter to be a good technical compromise for this requirement

- The desktop app should work on both Windows and Mac environments. We expect .net or C# knowledge

- AI can be used, as long as it's used with a paid account, disabling the model training option

We can't wait to start

Good luck to all applicants,

AI Shopping Assistant Developer – Amazon + SMS/Text MVP

Project Overview

We are looking for an experienced AI/full-stack developer to build an AI-powered shopping assistant.

For the first version, the system will focus only on Amazon and text/SMS. Voice calling and fully automated purchasing are not required for the MVP.

Customer Experience

The experience should be extremely simple.

For example, a customer texts:

“I need AA batteries.”

The system should:

1. Use AI to understand what the customer is looking for.
2. Search Amazon and find suitable products.
3. Compare relevant options based on factors such as price, ratings, specifications, and delivery.
4. Recommend a product to the customer with the important information and price.
5. Ask the customer to approve the purchase.
6. Once the customer says “Yes,” create a ready-to-purchase task for one of our employees.
7. The employee will manually complete the final purchase using the customer’s Amazon account.
8. The system should record the order information and send the customer confirmation/status information.

Amazon Accounts

Each customer will have their own Amazon account.

We need a secure and practical solution that allows our authorized employees to complete purchases on behalf of customers.

Security is extremely important. We want the developer to recommend the proper architecture for handling customer account access and payment-related information rather than simply storing passwords or raw credit-card information insecurely.

Employee/Admin Dashboard

Our employees need a dashboard where they can:

* See new customer shopping requests
* See the exact Amazon product the customer approved
* See the customer’s relevant order/delivery information
* Complete/manage purchasing tasks
* Update order status
* View customer and order history
* Handle requests that require human assistance
* See failed or unresolved AI requests

SMS/Text

Customers should be able to interact with the AI through normal SMS/text messaging.

Voice calling is not required for Version 1, but we may add AI voice calling later.

Scale

The system should be architected to support at least 200 customers actively using the service concurrently without significant performance degradation.

Future Expansion

Although Version 1 will focus on Amazon, the architecture should be designed so we can later add additional retailers such as Walmart, Target, eBay, and others without rebuilding the entire platform.

We may also add automatic purchasing/checkout in the future where technically and legally supported.

Developer Requirements

We are looking for someone experienced with:

* AI/LLM integrations and AI agents
* Full-stack application development
* E-commerce/product search integrations
* Amazon product data/integrations
* SMS APIs
* Secure authentication and customer data
* Payment security/tokenization
* Databases and scalable cloud infrastructure
* Employee/admin dashboards
* API integrations
* Building production-ready systems

When Applying

Please include:

1. How you would architect this system.
2. How you would obtain reliable Amazon product information, including current pricing and availability.
3. How you would securely handle customer Amazon account access.
4. Which AI, SMS, database, hosting, and other APIs/services you recommend.
5. How you would design the system so additional retailers can be added later.
6. How you would design it to support at least 200 concurrent customers.
7. Your estimated timeline and total cost for the MVP.
8. Examples of similar AI, e-commerce, SMS, or automation systems you have built.

Please do not send a generic proposal. We are specifically interested in developers who can explain how they would approach the Amazon integration and customer account security.
