We're excited to hear about these! ## Description Each customer project consists of 300 - 3,000 files: PDFs, construction drawings, scans, 3D models. Performant ingestion and a well-structured graph are the foundation for everything we are building - accuracy, ROI and user experience., * Designing and implementing new features to solve a specific user problem such as file navigation or document highlighting * From concept, to db schema to UI - own the full development lifecycle of customer-facing use cases Manage our web application & APIs * Maintain and improve our web application's security and performance; build out existing and new features Work on the construction ontology & project graph * Help model and evolve canonical entities of our customers * Contribute to entity resolution across sources: recognizing the same requirement, position or price across BoQs, contracts, drawings and bids * Build features so answers are evidence-linked and auditable, and decisions flow back into the graph Contribute to scalable data pipelines & integrations * Extend our multi-modal ingestion of unstructured documents - PDFs, scans, drawings, 3D models. Orchestrated and cost-efficient at scale * Build read/write integrations with customer systems (document management, ERP/AVA), so workflows complete work end-to-end Help build the abstraction layers that turn use cases into a platform * Contribute to the workflow harness, decision-trace standard and eval tooling so a new use case ships in ~1 month * Build reusable human review & approval surfaces where trust in AI output is earned Projects you would be involved in Past projects * Project & document versioning guaranteeing data lineage in construction projects * German tokenizer for construction-specific search * Document pipeline ingesting 10,000s of PDFs per day * Native BIM/DWG file support: ingesting and processing 3D models and CAD drawings * Swapped the search engine under production load (Meilisearch Turbopuffer) to unblock pipeline throughput and cut query latency * Document chunk highlighting in the PDF viewer and global document search via Fastify API Current projects * Design the ontology v1 + graph schema: core construction entities, evidence links, per-customer extension model * Develop systems to classify and organize project folders of 10,000+ files * Optimize queuing, logging and pipeline orchestration to process large document volumes * Templatize a workflow built for one project so it deploys to the next as configuration, not code Current Tech Stack It is still day 0 for Kuro. Therefore we are highly pragmatic with our tool choices. We believe in keeping it simple and moving quickly. You significantly help shape our tech stack decisions. * Web-App: Typescript * Database / Vector DB and File Storage: Supabase (postgress) / Trubopuffer / AWS S3 * Backend (Document Pipelines & applied AI): Fastify API / TS + Python for ML Services * Hosting: AWS Elastic Beanstalk * AI: Azure / OpenAI, Gemini, Cohere * Obsv., Eval. & Tracking: Langfuse, Datadog ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Debugging in the Dark](https://www.wearedevelopers.com/videos/1658-debugging-in-the-dark) - [TresJS a new declarative ThreeJS as Vue components](https://www.wearedevelopers.com/videos/543-tresjs-a-new-declarative-threejs-as-vue-components) - [This App Reached 10,000 Users in One Week.
