Project Overview We are looking for an experienced full-stack or front-end-heavy developer to build a clean, fast, and intuitive web interface on top of the Street Data API (Street Group). The platform will be used by UK estate agents to discover valuable housing insights in their local areas — helping them identify opportunities, analyse micro-markets, shortlist properties, and generate reports. In addition, the system should allow agents to export data and trigger direct-mail campaigns by sending selected addresses or reports to a connected mailing house for fulfilment. This is an MVP build with scope to expand into a commercial product. Primary Users UK estate agents and branch teams. Core User Workflows Agents should be able to: 1. Search an area (postcode, town, address, map). 2. View a summary of housing insights for that area. 3. Drill into individual properties. 4. Filter and rank properties. 5. Compare multiple properties. 6. Save properties and areas. 7. Export insights to CSV/PDF. 8. Send selected properties/areas to a mailing house for direct mail campaign fulfilment. 9. Generate simple branded reports for prospecting. Data Source The product will integrate with: • Street Data API (OpenAPI / REST / JSON). • Authentication via API keys or bearer tokens. • The OpenAPI schema will be provided. You must be comfortable: • Working directly from OpenAPI specs. • Generating typed clients. • Handling pagination. • Managing rate limits. • Implementing retries/backoff. • Caching common queries. MVP Scope 1. App Layout • Modern, professional dashboard UI. • Desktop-first responsive design. • Navigation sections: o Area Search o Property Search o Saved Items o Reports & Exports o Campaigns (Direct Mail) o Settings 2. Area Search & Insights • Search by postcode/town/address. • Optional map-based selection (radius/polygon). • Display area-level KPIs supported by the API. • Property lists ranked by opportunity indicators. • Filters: o Beds o Property type o Price bands o Tenure o Other available API fields. 3. Property Detail Page • Full property profile. • Key signals and attributes surfaced clearly. • Tooltips / explanations for non-technical users. • Save and compare options. 4. Comparison Tool • Compare up to 3–5 properties side-by-side. • Highlight differences. • Exportable view. 5. Saved Areas & Properties • Save searches and locations. • Notes/tags. • Local storage for MVP or lightweight backend persistence. 6. Reports & Exporting • CSV exports. • Branded PDF reports generated from HTML templates including: o Area overview. o Key stats. o Top opportunities. o Selected properties. 7. Direct Mail Integration (Important) The system should allow agents to: • Select a group of properties or addresses. • Export or transmit them to a mailing house for fulfilment. • Support: o CSV push. o API webhook integration (preferred). o Campaign reference tracking. • Simple campaign builder: o Campaign name. o Message/template selection. o Quantity. o Status (sent / pending / fulfilled). We will supply details of the mailing house or fulfilment API later — the architecture should allow this to be swapped or extended. Phase 2 / Nice-to-Haves • Team accounts. • User roles. • Shareable report links. • Activity history. • Advanced charts. • CRM integrations. • Webhook-based syncing. UX / UI Requirements • Clean, modern SaaS look. • Extremely simple for non-technical users. • Progressive disclosure of advanced fields. • Fast loading. • Excellent empty/error states. • UK-specific formatting. • Accessible and keyboard-friendly. Technical Requirements Architecture • Front-end: React + TypeScript ([login to view URL] acceptable). • UI framework: Tailwind / MUI or similar. • Optional backend proxy for: o API key security. o Caching. o Logging. o Rate-limit handling. • Maps: Mapbox / Google Maps / Leaflet (if included). Engineering Standards • Typed OpenAPI client preferred. • Pagination + retry/backoff implemented. • API secrets stored via env vars. • Clear README. • Modular architecture. • Basic automated tests. • Logging hooks. Deliverables • GitHub repository. • Deployed staging app (Vercel/Netlify/Render/etc.). • Environment-driven config. • Documentation. • Handover notes or short Loom walkthrough. • Instructions for connecting mailing house APIs. Acceptance Criteria An estate agent can: • Search an area. • View area insights. • Open property profiles. • Compare properties. • Save searches. • Export CSVs. • Generate PDFs. • Send addresses to a mailing house for a campaign. The app handles: • No-results states. • API failures. • Rate limits. • Large datasets. • Pagination. UI is polished and production-ready. What to Include in Your Proposal Please include: 1. Relevant past projects (dashboards, data platforms, OpenAPI integrations, mapping tools). 2. Suggested architecture and why. 3. Estimated timeline and milestone breakdown: o MVP. o Direct-mail integration. o Reporting. 4. Budget range. 5. Key risks or assumptions from reviewing the API docs. Budget & Timeline Open to proposals — please suggest: • Fixed-price or milestone-based delivery. • MVP timeframe. • Ongoing support options.

I can build your MVP web platform for UK estate agents, integrating the Street Data API with a clean, modern React + TypeScript interface using Tailwind or MUI, featuring area/property search, insights, comparisons, saved items, CSV/PDF exports, and direct-mail campaign functionality. I’d implement a lightweight backend proxy to secure API keys, handle caching, retries, pagination, and logging, with typed OpenAPI clients for safe, maintainable API consumption. The MVP can be delivered in roughly 6–8 weeks, with milestones for core dashboard features, reporting/export functionality, and direct-mail integration, followed by documentation, GitHub repo handoff, and deployment to Vercel or Netlify. I have experience building dashboards, OpenAPI-driven data platforms, and mapping tools, and can provide examples under NDA; the architecture prioritizes modularity, performance, and production-ready UX for non-technical users.

Hi there, We’ve built similar MVPs that integrate with OpenAPI and deliver valuable insights to users. For example, we developed a product that helps real estate agents find off-market properties by scraping data from multiple sources and generating leads. We also created a Chrome extension that allows agents to extract leads from property listing sites and send them directly to our platform. With our extensive experience in web scraping, we can ensure that the data we collect is accurate and reliable. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m looking forward to hearing more about this exciting project. Best, Adil
