• Build a clean backend (Python preferred) with a web framework, relational database, and background job processing suitable for long‐running document/AI tasks.
• Develop a modern front‐end (TypeScript/React or similar) with dynamic, schema‐driven forms and review panels wired to JSON schemas from the AI layer.
• Integrate a PDF viewing component with support for zoom/pan and overlaying highlights/annotations driven by AI outputs.
• Own deployment and basic DevOps: containerization, environment setup, reverse proxy, SSL, and pragmatic monitoring/logging for a small internal user base.
• Design integration points and data exchange with CAD, Revit, and LiDAR‐centric workflows, ensuring what you build can eventually sit alongside or connect to those environments.
• Iterate quickly based on in‐office feedback and real project usage; adjust flows to match the reality of CD production, not just idealized diagrams.

•  Solid experience across backend APIs (ideally Python) and modern front‐end frameworks (React/TypeScript or similar).
• Comfort building dynamic UIs from JSON schemas: forms, tabular views, and review panels that adapt as schemas evolve.
• Experience with relational databases, basic schema design, and migrations.
• Familiarity with containers (Docker) and deploying/operating small production web apps.
• Must have or quickly acquire working knowledge of CAD / Revit / LiDAR APIs and data structures; you're comfortable learning how these ecosystems represent drawings/models/point clouds.
• Interest in workflow tools, internal products, or expert‐facing software; AEC/engineering domain exposure is a plus.
