Summary

Full-Stack Developer | Freelance, Project-Based About Our Requirement We are seeking an experienced full-stack developer to work with us in transforming an early-stage concept into a polished, market-ready web and mobile application. This is a long-term opportunity to play a key role in shaping and continually improving the product architecture, user experience, and technical implementation while collaborating closely with the founders. Our objective is to create a subscription-based educational technology platform that helps families and students to better organize and manage academic information through a simple, intuitive interface The ideal solution will securely integrate commonly used educational tools and systems into a student dedicated web and mobile app providing users with a streamlined experience that reduces complexity and improves day-to-day organization. The project has progressed beyond the concept stage, with core functionality, a preliminary dashboard and workflows already defined. We are now looking for a developer with the skills to refine the platform, build a scalable and secure architecture, integrate with appropriate third-party services and APIs, and prepare the product for commercial launch. The Opportunity Based on the parameters noted above, we are seeking a mid-level full-stack developer to work directly with the project owners (non-technical but closely involved in every design decision) to help us finalize or vision and providing †he expertise to scale up our platform by applying secure real data integrations, adding durable data storage, and improving reliability — while preserving and enhancing the ease of functionally and user accessibility. Project Scope (Phase 1) • Interact with the founders to develop the means to migrate dedicated data from multiple platforms into our unique web based/mobile App. • Assist the founders in the creation and deployment of hosting and custom domain configuration. • Design and build a lightweight backend + database layer (e.g. Vercel serverless functions with a hosted Postgres database, or similar) to replace localStorage-only persistence • Evaluate whether to keep the current vanilla HTML/CSS/JS front end or migrate to a lightweight framework (e.g. Next.js), and implement that recommendation • Maintain and extend the accessibility standards already established (WCAG contrast, dyslexia-friendly typography, reduced-motion support) — nothing developed should regress readability for a dyslexic user • Set up a system of basic monitoring/error logging so issues surface before the subscribers are negatively (in terms or platform use) affected. • Document the codebase and deployment process clearly enough for a non-technical owner to follow Required Skills & Experience • 3+ years of professional full-stack development experience • Strong JavaScript/TypeScript, both front-end and back-end (Node.js) • Experience building and securing REST APIs, including OAuth 2.0 integrations with third-party services • Experience with serverless deployment (Vercel, Netlify, AWS Lambda, or similar) • Comfortable designing a database schema and working with a hosted database (Postgres, MySQL, or similar managed service) • Solid understanding of Git/GitHub workflows • Working knowledge of web accessibility standards (WCAG 2.1 AA or better) • Able to work independently against a scoped project brief with minimal day-to-day oversight • Experience integrating with EdTech platforms • Experience designing for neurodivergent users (dyslexia, ADHD, or similar) or prior accessibility-focused UX work • Familiarity with Next.js or similar lightweight React frameworks • Comfortable explaining technical tradeoffs to non-technical stakeholders Working Style This project is owned by a student’s parent, not a technical team — clear, patient, jargon-free communication matters as much as the code. You should be comfortable: • Proposing options in plain language and guiding the founders to understanding critical issues in order to (as a team) make informed decisions • Working within an existing, already-designed visual system rather than starting from scratch • Delivering in small, reviewable increments rather than one large handoff at the end Engagement Details Type: Freelance, project-based (fixed scope with a defined set of ending objectives) and a long-term potential for follow-on work) Location: Remote Estimated timeline: [Phase 1 – target implementation date – August 31, 2026] [Phase 2 – to include platform refinements based of in-use feedback and scaling the platform up to allow for beta testing of 10-20 users] Budget: [Phase 1 - $ 2,000.00] [Phase 2 - $ 1,500.00] Start date: [Immediately] How to Apply Please provide relevant past projects (especially any EdTech, accessibility, or OAuth/API integration work), your estimated timeline and desired rate (fixed or hourly) for the scope above, and any questions or alternative approaches you'd suggest for the backend/data layer. Please Note: A signed Non-Disclosure Agreement (NDA) is required before the start of this project engagement. This ensures that all confidential information shared throughout the project remains protected and that both parties have a clear understanding of their confidentiality obligations.
