AI saas platform development

Hi, I am looking for an experienced full-stack developer or small development team to provide a quotation for a secure, responsive AI-enabled EdTech SaaS MVP intended initially for the UK higher-education market. The platform is a web application rather than a standard informational website. Core MVP Requirements The MVP will include: Secure student registration/login and profiles Three user roles: Student, Expert and Administrator Structured diagnostic activities across six predefined academic capability areas Personalised student profile based on diagnostic results Configurable rule-based personalisation with selective AI analysis Practice activities with AI-supported formative feedback Independent reassessment and progress/profile updating Assessment-support functionality allowing students to upload assessment briefs, marking rubrics/criteria and optional learning outcomes AI/API-supported document analysis Personalised assessment-preparation priorities Lightweight expert marketplace/profiles and session requests Third-party video-service integration rather than proprietary video development Recurring subscription payments Basic administration/content-management functionality Basic reporting/flagging functionality AI/API The platform will integrate with an established AI provider through an API. Development of a proprietary AI model is not required. AI will be used selectively for written-response analysis, formative feedback, document interpretation and selected personalisation functions. The architecture should allow AI models/providers and educational rules to be modified later without rebuilding the whole application. Confidential Methodology The platform contains a proprietary diagnostic, scoring and personalisation methodology. Detailed scoring rules, diagnostic questions, decision trees, intervention-selection logic, reassessment thresholds, prioritisation methodology and proprietary prompts will not be disclosed at quotation stage. The system should therefore support configurable educational rules/content. Detailed methodology will be provided to the selected developer following appropriate confidentiality/IP arrangements. Security & Data Protection Security is a high-priority requirement. The platform will process student information, assessment documents and expert verification information. The solution should include: Secure authentication/password handling Role-based and least-privilege access Admin MFA HTTPS/encryption Private document storage Secure database configuration Secure API-key management Backup/recovery Security logging Appropriate data-retention/deletion capability Separation of development/test and production environments Development/testing should use synthetic data wherever possible. Production-data access should be restricted and controlled. The business will also have independent cybersecurity specialist oversight. Expert Verification Expert qualification/identity documents must remain private and separate from public expert profiles, with access restricted to authorised administrators. Payments The MVP should support recurring student subscriptions using an established payment provider such as Stripe or an appropriate alternative. Raw card information should not be stored by the application. Ownership The founder/business should control the principal production infrastructure, including hosting/cloud, database, source-code repository, AI/API accounts, payment account and domain. Subject to agreed third-party/open-source licences and payment terms, appropriate ownership/perpetual rights to commissioned custom source code and development must be transferred/provided to the business. Not Required for MVP The base quotation should exclude: Native iOS/Android apps Proprietary video conferencing Proprietary AI foundation model Advanced machine-learning recommendation engine Large-scale multilingual functionality Institutional dashboards Large content libraries Advanced automated surveillance/moderation The MVP should nevertheless be architected to allow future expansion. Please Provide Please send: Fixed-price MVP quotation Cost breakdown by major module Development timeline Proposed technology stack AI/API approach Hosting/database recommendation Security and UK-data-protection approach Testing/deployment approach Post-launch bug-fix/warranty period Ongoing maintenance hourly/monthly rates Estimated third-party running costs Relevant AI/SaaS/EdTech portfolio examples Development team location Details of any subcontractors Source-code/IP terms Any major exclusions from your quotation Please also indicate which features you would recommend simplifying or deferring to produce a cost-efficient MVP without compromising validation of the core product proposition. Following launch, I would also be interested in retaining the selected developer for technical maintenance and future development during the following 2–3 years, subject to mutually agreed commercial terms. Please provide your quotation based on the requirements rather than asking for my target development budget. Thank you,
