Hi — Elias here from Miami. I see you’re looking to extract hidden APIs and build an e-commerce SaaS platform. Your goal is to create a robust solution that not only meets current needs but can also scale and adapt over time. What usually matters most here is ensuring the system is not just functional but also maintainable and secure. A common issue in projects like this is managing API integrations alongside workflow complexities. It looks straightforward initially, but the nuances of data handling and user roles can lead to significant challenges if not addressed early. My approach would involve structuring the application with a focus on modularity and clear separation of concerns. This way, we can ensure that updates and future expansions are streamlined. I’ve worked on similar projects, particularly in e-commerce, where I implemented scalable API integrations and maintained high levels of performance. A few questions to better understand the scope: Q1 – What specific e-commerce features do you envision that will require custom API integration? Q2 – Are there any particular user roles and permissions that we need to consider? Q3 – How do you plan to handle data synchronization between your platform and third-party services? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hi, I understand you need a complete analytics/data SaaS with dashboard, user accounts, subscriptions, shop, payments and a reliable REST API, using HTTP/HTTPS integrations without browser automation. I can build this with **Python or Node.js/TypeScript**, PostgreSQL and a scalable API-first architecture, including authentication, billing, product management, rate limiting, logging and secure data handling. For undocumented APIs, I’ll analyse the permitted HTTP behaviour, map request/response structures and build a maintainable integration layer. I can also add practical **AI automation** for data validation, anomaly detection, API monitoring and support workflows using current 2026 best practices. I’m ready to review the reference service and start ASAP.

Hi there I can develop a complete SaaS analytics/data platform with a secure backend, user dashboard, subscriptions, shop, payments, authentication, and REST API. I have already developed similar SaaS and data-driven platforms involving complex APIs, user roles, subscription workflows, and scalable backend architecture. My development approach: • Analyze the existing service and required data/API behavior • Reverse-engineer permitted HTTP/HTTPS requests and response structures • Build the backend using Python/FastAPI or Node.js/TypeScript • Design database, authentication, authorization, and API layers • Develop responsive dashboard, user accounts, shop & product management • Integrate subscription plans, billing, and payment gateway • Build, test, document, and deploy the complete REST API I’ll ensure the implementation uses HTTP/HTTPS requests only, without browser automation tools. Two questions: Do you have access to the existing service/API that we can analyze? Which payment gateway and subscription model do you want to use? Thanks Rahul

@raheel2k29

Hello, your SaaS vision combines reverse-engineered HTTP data access with subscriptions, payments, user accounts, a shop, dashboard, and a reliable REST API. I can help structure this as a maintainable platform with clear service boundaries, secure authentication and authorization, resilient request handling, database-backed billing, and documented API contracts. A useful improvement would be an adapter-based data layer, keeping undocumented HTTP integrations isolated so changes can be managed without disrupting subscriptions or dashboard functionality. I will also prioritize rate limiting, retries, logging, and validation from the beginning to improve reliability. I’m ready to approach the platform systematically and deliver a strong foundation for future expansion. Regards Muhammad

@seefattechnologi

SURE--------------------I got the scope of work-------------------From hidden HTTP endpoints to a subscription-powered analytics SaaS—I can turn the existing service’s data flow into the actual product, without relying on browser automation. I will reverse-engineer the required HTTP/HTTPS request layer, mapping authentication, parameters, responses, pagination, errors, and data structures, then build a stable backend around it using Python or Node.js/TypeScript. The SaaS will include the full platform layer: REST API, user accounts, authentication/authorization, analytics dashboard, shop/products, subscription plans, billing and payment integration, backed by a clean database architecture. I will keep the data acquisition layer isolated from the customer-facing SaaS, making it easier to test, maintain, and adapt when upstream API behaviour changes. Quick Questions Do you have authenticated access to the existing analytics service for endpoint analysis? Which payment provider and subscription tiers should the MVP support? Thanks!!!

@Hammadhassan21

Hello there I’m interested in your SaaS platform project and can help build the backend, dashboard, user accounts, subscriptions, shop, payments, and REST API as one structured system. For the data layer, I can work with HTTP/HTTPS requests directly and build a reliable integration around the required endpoints, authentication, request/response handling, rate limits, errors, and data normalization—without Selenium, Playwright, Puppeteer, or browser automation. I’d structure the backend with clear authentication/authorization, database models, subscription and payment states, API services, and scalable data handling so the platform remains maintainable as usage grows. My workflow will cover architecture, HTTP/API integration, database setup, dashboard and account system, billing/payment integration, API development, testing, security, and deployment. Portfolio: https://www.freelancer.com/u/Hammadhassan21 Could you share the existing service/API you want the platform to integrate with and whether you already have the required API access or sample HTTP requests/responses? Best regards, Hammad Hassan

Hi there I can build the complete SaaS platform with a modular backend, dashboard, user accounts, subscriptions, shop, payments, and a documented REST API. I can work with Python or Node.js and TypeScript, using PostgreSQL or another suitable database depending on the data model. I will design secure authentication and authorization, subscription and billing workflows, product management, payment processing, API access controls, and a scalable backend architecture. For the data layer, I can analyze documented or authorized HTTP and HTTPS traffic to understand request formats, parameters, authentication flows, response structures, pagination, and error handling, then implement a clean server side integration without browser automation. I will keep the integration isolated behind service modules so changes to the upstream API can be handled without affecting the rest of the platform. The dashboard will provide account management, subscription status, usage or analytics views, product and billing information, and API related controls as required. I will also include validation, logging, rate limiting, secure credential handling, and clear API documentation. I can deliver the source code, database setup, deployment configuration, documentation, and testing for the complete SaaS workflow. Best Jafarali

@AneesaIBA

Hi there, I have read and understood the project details. You need a complete analytics/data SaaS platform with user accounts, dashboard, subscriptions, billing, shop functionality, payments, and a REST API, with the data layer communicating through HTTP/HTTPS rather than browser automation tools. I can build the backend using Python or Node.js/TypeScript with PostgreSQL, secure authentication and RBAC, REST APIs, subscription management, and Stripe or another suitable payment provider. For the HTTP integration, I can inspect documented or legitimately accessible API behaviour, request/response structures, authentication flows, pagination, rate limits, and error handling, then create a maintainable integration layer without Selenium, Playwright, Puppeteer, or browser automation. Could you share the analytics service you want the platform to be inspired by and clarify which data/functions need to be reproduced? Also, do you have authorised access or API credentials for the source service, and is there an existing UI/design or technical specification for the SaaS dashboard? I can structure the project into milestones covering the data/API layer, authentication and dashboard, subscriptions/payments, shop, and final integration/testing. Once I review the target functionality and access method, I can provide a realistic fixed-price quote and timeline. Cheers, Rabia Shaikh

@crtvecode

When a project requires building a complete SaaS platform with specific functionalities, the underlying issue often lie in making sure a cohesive integration of all components. To avoid any risk of data lost or disruption to your existing services, I will work in a safe staging environment, making sure your live site remains untouched throughout the process. Safe staging build: full platform built on a private staging area first, live site untouched. API reverse engineering: undocumented HTTP APIs analyzed and integrated into the backend. User account setup: secure authentication and authorization for all users. Payment integration: smooth setup for subscriptions and billing processes. Could you clarify if there are any specific payment gateways you prefer for integration? Rajavel

@Joya1996

Building a SaaS around an undocumented data source only works if the HTTP layer is mapped correctly first; otherwise subscriptions, dashboards, and customer access get built on top of something fragile. My approach would be to verify the request patterns, authentication method, and response structure early, then implement the backend, database, and user-facing product around a stable service layer. I work on custom platforms where authentication, billing, role permissions, APIs, and structured backend logic matter more than just the frontend. Python or Node/TypeScript are both fine here, but the better choice depends on whether you expect heavier data processing, queue jobs, or mostly standard app flows with a clean API surface. A couple of points I’d want to clarify before finalizing scope: - Will users have usage-based limits/credits, or only plan-based access? - How many dashboard sections or key modules do you expect in v1? - Do you need an admin panel for managing users, subscriptions, products, and API access keys?
