ppCHoNova is digitalizing chocolate manufacturing. Using proprietary ultrasound-based sensing, we enable manufacturers see what is happening inside their production process in real time and turn that data into cost savings, productivity gains and quality optimization. Already deployed across multiple brands in 5 countries, we are scaling our decision-support platform: it consolidates sensor, process and product data, flags deviations before they become defects, and — as our physics-guided ML roadmap matures — recommends what to change and why. /p h3Tasks /h3 pYour mission is to architect and build the next generation of our customer-facing web application on a modern, professional stack (React + TypeScript), turning rich production data into an interface a plant manager understands at a glance. /p h3What You’ll Do /h3 ul liArchitect and build a web app frontend, replacing our Streamlit framework with a robust, maintainable React + TypeScript application /li liCreate interactive dashboards for real-time data: production monitoring with traffic-light indicators, control charts, reference envelopes with confidence bands, zone-resolved run summaries, and trend views. /li liMake statistics intuitive — our platform surfaces statistically rigorous outputs (SPC, repeatability, confidence intervals); your job is to make them readable without a statistics degree. /li liIntegrate with our FastAPI back-end and time-series data layer, and implement backend features yourself when needed. /li liOwn quality and shipping: CI/CD for the frontend, tested releases, documentation, staging/production discipline. /li /ul h3Requirements /h3 ul liDemonstrable experience building real web apps — show us your portfolio: React + TypeScript in production, or serious personal/academic projects. /li liStrong data-visualization skills (Plotly, Recharts, D3 or similar), ideally with time-series or scientific data. /li liAn eye for UI/UX: you can derive a coherent design system from an existing brand identity and apply it consistently across an application. /li liAbility to ship independently and take ownership of an entire surface area. /li liPython / FastAPI proficiency — you can implement backend features when needed. /li /ul pNice to have: /p ul liUnderstanding of CI/CD for frontend applications. /li liInterest in scientific, industrial or data-heavy applications. /li liExperience with authentication, role-based access, or multi-tenant SaaS. /li liExposure to manufacturing, IoT or sensor-data products. /li /ul h3Benefits /h3 ul liReal impact. Your dashboards run on the factory floors of leading chocolate brands from day one. /li liEnd-to-end ownership. You own the customer-facing frontend. /li liDeep tech, tangible product. Physics, ultrasound, statistics and machine learning — applied to making better chocolate. /li /ul pCHoNova is digitalizing chocolate manufacturing.
