Build MVP Web App – AI-Assisted Project Planning & Readiness System Job Description We are looking for an experienced developer or small team to build an MVP web application for a construction / project planning control system. This is not a generic task manager or scheduling tool. The system works on a weekly control cycle and uses PDF programme uploads to generate a 6-week lookahead, classify activities (Red / Amber / Green), manage readiness actions, and output weekly plans. A full developer pack is already prepared (architecture, data model, API outline, Jira backlog, business rules). We are looking for delivery, not product design. Scope (MVP) Web app (frontend + backend) User roles & permissions Weekly PDF upload and versioning Activity extraction from PDF (basic parsing + manual correction) 6-week lookahead logic RAG (Red / Amber / Green) classification Action / constraint management Role-based dashboards Weekly exports (PDF / CSV) Audit logging Important constraints The system must NOT directly edit project schedules Input is via weekly PDF uploads only Logic is time-based, not priority-based This is a control system, not a scheduler Tech Stack (Open to suggestion) Frontend: React (preferred) Backend: Python (FastAPI) or Node (NestJS) Database: PostgreSQL File storage: cloud object storage Deployment: Docker-based What to Include in Your Proposal Please include: Recommended tech stack Estimated timeline (weeks) Estimated cost Team size / role breakdown Relevant experience (especially workflow, document-based, or planning systems) Nice to Have Experience with PDF parsing Experience with construction, engineering, or operations software Strong understanding of role-based systems and auditability

What stood out to me is that this is a control system, not a planner or scheduler. Weekly cadence, PDF-in → governed logic → auditable outputs. That distinction matters, and it’s clear you’ve already done the hard product thinking — you’re looking for execution against a defined pack. I’d deliver this as a backend-driven, rule-first MVP, staying strictly within your constraints (no schedule editing, no priority logic, PDF-only inputs). Recommended stack * Frontend: React * Backend: Python + FastAPI * DB: PostgreSQL * Storage: S3-compatible object storage * Deployment: Docker, environment-separated Implementation approach * Weekly PDF upload with immutable versioning * Activity extraction via basic parsing + structured manual correction * Deterministic 6-week lookahead engine * RAG classification driven by time/readiness rules * Action/constraint tracking tied to activities and weeks * Role-based dashboards and exports I’ve built document-driven workflow systems where audit trails, time-based logic, and human override were non-negotiable — including ops and planning platforms where “control” and “visibility” mattered more than automation hype. Estimate * Timeline: 8–10 weeks for a production-ready MVP * Team: 1 senior backend, 1 frontend * Cost: fixed-price, aligned after backlog confirmation Happy to review the developer pack and walk through how I’d map it sprint by sprint. Best regards, Jenifer

Hello, I will build a focused MVP web app for AI-assisted project planning and readiness, designed for a weekly control cycle in construction. The MVP includes a web app (frontend + backend) with roles and permissions, weekly PDF upload with versioning, and a 6-week lookahead that classifies activities as Red/Amber/Green. It will extract data from PDFs with basic parsing and allow targeted manual corrections, while the system never edits the original schedules. The 6-week lookahead logic will be time-based, and the platform will support action/constraint management, role-based dashboards, and weekly exports (PDF/CSV) with audit logging for traceability. I will deliver using a lean, modular stack that you can test quickly: Frontend React, Backend Python FastAPI or Node NestJS, PostgreSQL, cloud object storage, Docker deployment. I will reuse your developer pack (architecture, data model, API outline, Jira backlog, business rules) to minimize risk and speed up delivery, with a focus on correctness, security, and maintainability. Can you confirm the exact PDF upload formats, versioning rules, and acceptance criteria for the 6-week lookahead? Best regards,

Hey there, I've gone through your requirements and and I've been building workflow and document-based systems for about 7 years now. Here's what I'd deliver for the MVP: Web app with user roles and permissions. Weekly PDF upload system with versioning. PDF parsing to pull out activities (with manual correction option). 6-week lookahead logic based on your business rules. RAG classification system (Red/Amber/Green status for activities). Action and constraint management tied to activities. Role-based dashboards showing what each user needs to see. Weekly plan exports as PDF and CSV. Full audit logging for compliance and tracking. Built so the system never touches the actual project schedules - just reads PDFs, processes them, and outputs control data. Time-based logic, clean separation of concerns. Timeline: About 10-12 weeks for complete MVP built, tested, and deployed. Tech stack I'd recommend: React frontend, Python with FastAPI backend, PostgreSQL database, AWS S3 or similar for file storage, Docker containers for deployment. I've built similar systems before - document workflow platforms, compliance tracking tools, and operations management systems where audit trails and role-based access were critical. Talk soon, Kamran.

Hi, This is Elias from Miami. I checked your brief and I understand this is a weekly control system for construction planning, not a task manager and not a scheduler. The only input is weekly PDF programme uploads (with versioning), and the app outputs a 6-week lookahead, classifies activities as Red/Amber/Green, manages readiness actions/constraints, and produces weekly exports (PDF/CSV) with audit logging. No direct schedule edits, and logic is time-based, not priority-based. Since you already have a full developer pack (architecture, data model, API outline, Jira backlog, business rules), I can focus purely on delivery and keep changes tight to your spec. Recommended stack: React frontend, FastAPI backend (Python is strong for PDF parsing + pipelines), Postgres, S3/Azure Blob for storage, Docker deployment. Additionally, a few project-specific questions: -Q1 What format are the uploaded programmes usually in (P6 export PDF, MS Project PDF, or mixed), and do they have consistent tables or is it free-form text? -Q2 For manual correction, do you want an in-browser “activity table editor” after extraction, or a simpler CSV-style correction step before saving the weekly version? -Q3 For RAG classification, are the rules fully deterministic from your pack, or do you also want a RAG “explanation” field (why it’s red) stored for audit? Looking forward to hearing from you. Regards.

Dear Client, I’m keen to deliver your MVP AI-assisted project planning and readiness system and can focus squarely on execution using your existing developer pack. I recommend a React frontend with a FastAPI backend, PostgreSQL for structured audit-safe data, and cloud object storage for versioned PDF uploads, all deployed via Docker. I have experience building document-driven workflow systems with role-based access, audit logging, and time-based control logic, including PDF parsing with manual correction loops and RAG classification. An MVP of this scope can be delivered in approximately 8–10 weeks by a small team (1 backend, 1 frontend, shared QA), with a fixed, transparent cost aligned to milestone delivery and weekly control cycles rather than scheduling logic. Are the PDF programme formats relatively consistent, or should the parser expect multiple layouts from the start? Do you want RAG classification rules to be fully configurable by admins or fixed for the MVP? Is the weekly export format already defined, or should templates be created as part of delivery? Best regards, Arslan Ahmed

Hi The critical technical challenge here is reliably turning weekly PDF programme uploads into structured activities and a correct 6-week lookahead without ever behaving like a scheduler or editing plans. I can deliver this MVP with a React frontend and a FastAPI (or NestJS) backend on PostgreSQL, with versioned PDF storage in object storage and Dockerized deployment. For extraction, I implement robust PDF parsing into normalized activity records plus a review UI for manual correction so downstream logic stays accurate. The weekly control cycle is enforced server-side (period locking, versioning, audit logs) to ensure the system remains time-based and traceable. RAG classification and readiness actions are modeled as rule-driven state with constraint/action workflows tied to roles and permissions. Dashboards are role-based and optimized for the weekly cadence, with exports to PDF/CSV generated from the same canonical data. The result is a control system that is auditable, maintainable, and aligned with your developer pack rather than reinventing product design. Thanks, Hercules

Hi Philip R, Thank you for posting this good task! After reviewing your description, I’m confident I can deliver this as a control-focused, document-driven system rather than a generic scheduler, fully aligned with your weekly PDF-based workflow and audit requirements. I'd recommend React for the frontend, Node.js (NestJS) for the backend, and PostgreSQL with cloud object storage, as this stack is well-suited for role-based systems, file versioning, and time-based business logic. My relevant experience includes building workflow-heavy web apps, document-based systems (PDF ingestion, parsing, correction flows), and planning/control dashboards where data accuracy, traceability, and audit logs were critical. I have also worked on systems with role-based permissions, approval cycles, and exportable reports (PDF/CSV) used in real operational environments. For the MVP scope listed, I estimate 6–8 weeks for delivery, including parsing logic, RAG classification, dashboards, and exports. Estimated cost would be $4000–$5000 USD, depending on PDF complexity and iteration cycles. I typically work solo as a full-stack developer but can scale with a Devops or QA support if needed. I follow clean, maintainable coding standards (Airbnb-style JS practices) and focus on shipping stable, production-ready MVPs. Looking forward to discussing your developer pack and moving this into delivery. Best regards, Diah
