I need a Mendix-based application dedicated to students that streamlines the full assignment-submission flow. The core of the app lets each student submit coursework online, while lecturers or tutors can review, comment and grade inside the same environment. Key functionality • Assignment submission: intuitive form where a student selects the course, uploads work and hits submit. • File upload support: any common document type (PDF, DOCX, images) must store safely in Mendix file storage and remain linked to the assignment record. • Submission-deadline reminders: automatic in-app and email notifications that trigger X days before cut-off and again on the day itself, driven by Mendix microflows and scheduled events. • Peer-review system: after the deadline t...
I need an experienced Ignition developer who can jump straight into two clear areas of my SCADA project: rich data-driven visualisation and robust alarm configuration. Data visualisation scope The screens must draw directly from our SQL databases and a handful of real-time sensor tags already exposed in Ignition. I will provide the queries and OPC tag paths; your job is to turn that information into intuitive front-end elements: line, bar and pie charts for live KPIs, tabular reports for historical trending, plus a set of data-entry forms to let operators create and edit production recipes. Everything has to feel cohesive inside Perspective and respect our existing colour palette. Alarm configuration scope In parallel, I need help setting up alarm conditions on key process var...
...engineer who can join me Monday-Friday, 9 AM-5 PM CST, and communicate clearly in English throughout the day. This role centres on a commercial application that spans Healthcare, Finance, and Retail, so you’ll be switching contexts and datasets often. Day-to-day you’ll be: • Exploring raw data, cleaning it, and shaping robust feature sets • Designing and training predictive models and optimisation algorithms • Deploying, monitoring, and continually improving those models in production • Owning the backend APIs, batch pipelines, and any lightweight front-end hooks needed to surface the insights We work primarily in Python with TensorFlow/PyTorch, SQL, and a cloud stack (AWS + Docker/Kubernetes), though I’m open to comparable too...
...go. Core scope The platform must launch with seamless payment gateway integration, and I have already chosen Stripe as the processor. All transactions will be subscription-based rather than one-off purchases, so experience handling recurring billing, webhooks, and secure token storage is a must. Tech stack & approach • Back end: ASP.NET Core (latest LTS preferred), Entity Framework Core, SQL Server • Front end: React with functional components, TypeScript, and modern state management (Redux Toolkit or React Query) • Deployment: Container-friendly code that can be pushed to Azure or AWS; CI/CD pipelines set up in GitHub Actions are a plus. Key deliverables 1. High-performance RESTful API that manages products, plans, customers, and Stripe subscr...
