I am looking for an experienced Full Stack developer to create a SaaS service for online stores.
Service idea:
The client uploads a link to their product feed (XML or CSV). The service automatically retrieves the products, takes their photos, and creates new advertising images based on ready-made templates: price, discount, logo, promotional tags, etc.
There should also be a simple template editor in the service. In it, the user will be able to:
upload their logo;
choose brand colors;
change the text on the tags;
select where the price will be placed;
select where the discount will be placed;
enable or disable individual elements of the template;
preview how the advertising image will look.
After this, the system generates a new product feed with updated images that can be used in Meta Ads, Facebook, Instagram, or Google Shopping.
What needs to be implemented:
User cabinet.
Connection and processing of XML/CSV product feeds.
Saving products in the database.
Generating advertising images based on templates.
Simple template editor.
Uploading a logo and setting colors.
Previewing ready creatives before generation.
Storing images in the cloud.
Automatic feed updates.
Generating a new feed with updated links to images.
Subscription system and online payment.
I also want to discuss the possibility of using AI in future versions of the service.
I am interested in your assessment and suggestions regarding the implementation of such functions:
automatic background removal of the product;
improving photo quality;
automatically determining the best place for the price, discount, and other elements on the image;
generating advertising backgrounds for the product;
automatically creating new variants of creatives for A/B testing;
AI generation of advertising banners based on the product and template;
automatically creating advertising texts and headlines for products.
Please evaluate:
which of these functions are advisable to implement already in the MVP;
which are better left for the next stages of product development;
which AI services or models you recommend using;
the approximate complexity and cost of implementing each function.

Good day, Alla!
I have reviewed the feedback from other specialists on your project. I want to help you have the opportunity to communicate not only through GPT chats.
For now, I will refrain from making an offer, as it is important to understand the ultimate goals of creating the SaaS service. To do this, please clarify:
- What are the launch timelines: is an MVP needed for a quick start?
- Is there a detailed specification or vision for the service?
- What is the goal of the service: advertising, automation, integration?
- Are you planning a unique design or a template?
… - What AI services or models do you plan to use?
Factors affecting cost and timelines:
1. Complexity of functionality: integration with XML/CSV feeds, image generation, template editor.
2. Subscription system and online payment.
3. Use of AI for automation, such as background removal.
4. Data storage in the cloud and feed updates.
5. Level of detail in the specification and availability of ready-made solutions.
At the initial stage, it is important to agree on the final vision of the SaaS service, which we will reflect in the technical specification. This will help understand what solutions are already available on the market and create something unique.
I understand the importance of integrating your service with feeds for automation in online stores. The idea of creating advertising images based on templates is relevant for increasing advertising effectiveness on Meta Ads, Facebook, Instagram, and Google Shopping platforms.
The next step is to briefly discuss the project and understand how well we fit each other. Let's finalize the details in correspondence or at a meeting.

Hello! I have technical experience in Python development and data processing (XML/CSV), so I understand the architecture of such a service.
The project is interesting, and here is my vision for implementation:
MVP (Minimum Viable Product): For the first version, I recommend focusing on stable feed processing and a basic image generator using libraries (such as Pillow or ImageMagick). AI features (background removal, photo enhancement) are better integrated through ready-made APIs (like Remove.bg or OpenAI Vision), rather than building from scratch — this significantly reduces the cost of developing the MVP.
Architecture: I suggest using Django (for the admin panel and business logic) + Celery (for background image generation), as this stack is ideal for handling large volumes of data and task queues.
AI part: I fully support the use of AI, but at the MVP stage, it is advisable to limit it to automatic background removal. Everything else (text generation, A/B options) is perfect material for V2.0, when you have a user flow.
…
I am ready to discuss the details, estimate timelines, and outline a roadmap for the MVP. I have experience implementing similar projects where automation was key.
Looking forward to your response!

Hello! I can fulfill your order as I have experience in building high-load parsers, e-commerce automation systems, and integrating generative AI models. Here are specific implementation proposals and project estimates:
Backend and queues: Node.js (NestJS) + BullMQ + Redis. Processing feeds of 10,000+ products will occur asynchronously in background threads to prevent server crashes due to load.
Image generation (MVP): Sharp or Canvas library on the server. Overlaying prices, tags, and logos will be done by code in milliseconds. This is free for you and does not require expensive GPUs.
Template editor: React + Konva.js / Fabric.js for creating a UI builder (drag-and-drop elements and preview).
Storage: Cloudflare R2 (no charge for outbound traffic when Facebook/Google will be mass downloading images).
What we do in MVP:
… Automatic background removal: Critical for products. We implement this through a fast API (Clipdrop / remove.bg) or connect a lightweight local model RMBG-1.4.
Text/title generation: To improve CTR of product names, we integrate GPT-4o mini or Hermes 3 (this is cheap and fast).

Hello!
The idea is clear — essentially, this is a SaaS for automatic generation of advertising creatives from a product feed, with a template editor and subscription. The project is interesting, I see how to implement it.
Regarding the stack: backend on FastAPI, image generation via Pillow (templates, banners, prices, logos), template editor on Fabric.js, cloud for images — S3 or Cloudinary, subscriptions — Stripe, LiqPay, or WayForPay to choose from. A new feed with updated links to images is generated automatically after creation.
About AI: for the MVP, I would recommend implementing background removal now (rembg — free, works locally, gives good results) and generating advertising texts/titles through OpenAI — this is real value for the user without significant costs. Everything else (background generation, A/B variants, photo quality improvement) — these are next versions, requiring separate AI services and a larger budget.
One point I want to clarify privately — the template editor: a full-fledged drag-and-drop canvas and configurator through a form (selection of positions, colors, toggling elements on/off) — this is a very different scope of work. This will affect the final assessment of timelines.
…
I hope for collaboration!

I am implementing a project focused on creating a scalable SaaS product, rather than just a standalone tool for generating images. Such systems require a well-thought-out architecture, as they simultaneously combine working with product feeds, image processing, cloud storage, generating new feeds, personal accounts, and a subscription model. Special attention will be paid to ensuring that the MVP is as useful as possible for the business and allows for seamless future development of the service. The basic functionality will be built in such a way that AI capabilities can be easily integrated later without the need to rewrite the entire system. In the first phase, it is advisable to implement image generation based on templates, a template editor, previews, automatic feed updates, cloud storage, and a subscription system. AI functions should be gradually introduced, as they significantly increase complexity and costs. Future versions may utilize OpenAI, Gemini, Flux, Stable Diffusion, Ideogram, Replicate, Cloudinary AI, or AWS Rekognition. Automatic background removal and photo enhancement are considered medium complexity features, while generating advertising backgrounds, A/B variants of banners, and automatically determining the optimal placement of elements are more complex tasks. This approach will allow for a quick market launch of the product and gradual expansion of its capabilities according to user needs.
Work plan:
Designing the architecture of the SaaS platform.
Developing user personal accounts.
Implementing XML and CSV feed imports.
Storing products and images in the database and cloud storage.
Creating a template builder and preview system.
Generating advertising creatives and new product feeds.
Setting up automatic data updates.
… Implementing subscriptions and online payments.
Testing performance and scalability.
Preparing the architecture for future integration of AI capabilities.

Hello! I can implement this service as a SaaS solution: user cabinet, import of XML/CSV feeds, storage of products in the database, template builder, generation of advertising creatives, cloud storage of images, automatic feed updates, and creation of a new feed for Meta/Google Shopping. For the MVP, I recommend initially implementing templates, image generation, previews, and a subscription system, while AI functions (background removal, background generation, A/B creatives, texts) should be moved to the next stage. I will suggest the optimal stack and AI services (OpenAI, Replicate, Stability AI, Remove.bg). The estimated cost of the MVP is from $3000, with a development period of 6–8 weeks. I am ready to discuss the architecture and implementation stages in detail.

I see the task as an MVP based on a template generator with a feed pipeline and processing queue: XML/CSV → product normalization → image generation based on templates → storage in S3/analog → formation of a new feed. For the template editor, it is optimal to implement drag & drop with fixed blocks (price/discount/logo) to avoid a complex no-code constructor at the start and to bring the product to market faster. AI functions can logically be added in stages, starting with background removal and auto-generation of backgrounds; the rest is better left for the phase after the first revenue.
I am ready to take this on and break the process into stages to quickly create a working MVP and lay the architecture for AI-based extensions. Let's discuss the details and priorities.

Alla, hello! I understood the essence: this is not just a cabinet with feeds, but a generator of advertising creatives where the whole value lies in the template engine rendering images consistently and quickly even for thousands of products. The most important technical decision at the start is the choice between server-side rendering via Sharp or Canvas and client-side rendering via Fabric.js, as this affects both the quality of the preview in the editor and the speed of feed generation. For the MVP, I would only use AI for background removal through the rembg or remove.bg API, because clean product photos are the foundation for everything else; the rest of the features can be added later. Write to me privately: is there any reference service you are focusing on for UX, and how many products does a typical client plan to process in the feed?
