Product Design (UI/UX) Assistance – Figma & User Flows

I’m looking for a UI/UX designer to help finish and expand an existing product in Figma. The main concepts and initial designs are already there, so this is not a project where you have to start everything from scratch. I mainly need help designing additional screens, improving the existing UI and working through user flows based on the direction we already have. We have started a design system with colors, typography, text sizes and some basic components. It’s still early, so I’d also like someone who can help bring more consistency and structure to it as the product grows. You should be comfortable looking at existing designs, understanding the product flow, suggesting UX improvements and turning those ideas into polished Figma designs. This will be an ongoing project, so I’m looking for someone who can work with the existing direction and continue improving the product over time.

Senior Mobile App Developer / Full-Stack Team – Build FitAdapt AI

We are looking for an experienced mobile developer or small development team to build FitAdapt AI, a personalized fitness app for iOS and Android. The main idea behind the app is simple: the workout should change based on the user's current condition instead of giving everyone the same workout. The app will use information such as the user's fitness level, goals, previous workouts, performance and daily readiness to recommend a Light, Moderate or Heavy workout. We already have the product idea and initial UI direction. We now need a developer or team who can turn it into a polished and scalable MVP.

Data Analyst Needed for Excel Data Cleaning & Reporting

I have an Excel file with around 5,000 rows of sales data, including dates, customer names, products, quantities, prices and sales regions. The data needs to be cleaned and organized before I can use it for reporting. There are some duplicate records, missing values, inconsistent date formats and numbers that are currently stored as text. I need someone who can clean the file, organize the data properly and create a simple summary report. The original data should remain untouched in a separate worksheet. The cleaned data and reporting should be placed in new worksheets.

Prompt Engineer with Mechanical / Civil / Aerospace Engineering Background

We are looking for a Prompt Engineer with a strong engineering background to support an AI work-trial and evaluation project. This role is not only about writing prompts. You should be able to understand engineering problems, review AI-generated solutions, check the technical reasoning and calculations, and identify where an AI response is wrong, incomplete or based on a weak assumption. You will create prompts for AI agents that are solving technical engineering problems. The prompts should clearly explain the requirements, assumptions, constraints and expected output so that the AI can produce useful engineering work. You will also review different AI-generated solutions and compare their approaches to determine which one is technically stronger. A background in Mechanical, Civil or Aerospace Engineering is important for this project. Experience with LLMs, prompt engineering, AI evaluation or technical QA is a strong plus.

E-commerce Product & Pricing Updates – Python

We are looking for someone who can help us maintain and update our custom e-commerce platform on a regular basis. Our vendor has already developed the platform, and our main need is to make weekly updates such as adding new products and changing product prices. The platform uses Python for item style builds and pricing configuration. You will not need access to the source code, and the Python work involved is relatively simple. Before starting the actual work, we will provide basic training through our internal portal. This training is required because it will show you how our platform works and how products and pricing need to be configured. After the training, the work will mainly involve adding products, updating product information and making pricing changes according to our requirements. We are looking for someone reliable who can work with us on a regular basis and is comfortable learning an internal system.

Blender 3D Artist for Architectural Visualization & XR

Irish National Opera is looking for a freelance 3D artist or architectural visualiser to create a concept-level 3D model of a room that is being renovated within one of our buildings. The model will mainly be used to show the proposed look and feel of the renovated space to internal and external stakeholders. It will also be used as a starting point for XR experiences in the space. This does not need to be a survey-grade or construction-grade model. The main priority is creating a good-looking and believable representation of the proposed space while staying as close as possible to the available 3D scan and design materials. We can provide a 3D mesh scan of the existing room, basic architectural layouts, artist renderings of the proposed design, and photographs of the current space. There are no full construction measurements available, so the 3D scan should be treated as the main reference for the dimensions.

Computer Vision Architecture Review – RGB-D 3D Reconstruction for Livestock

We are building an agritech platform that uses camera data to estimate physical traits of livestock, including body condition and structural measurements. We are looking for a computer vision expert to review the architecture of the camera-vision part of the system. This is a fixed-price architecture review, not a development or implementation project. The system uses handheld RGB cameras as well as RGB-D stereo depth cameras, specifically Intel RealSense D400 series, for higher-quality fixed-position capture. You will receive a written technical specification covering the sensor setup, capture strategy and data model. Your job will be to review the proposed approach and give us an independent technical opinion on what works, what may cause problems, and what you would change. The main focus is dense 3D reconstruction and structural measurement from depth and surface geometry. This is not an object detection or image classification project. Experience with photogrammetry, stereo vision, RGB-D systems, 3D reconstruction or point-cloud based measurement is therefore much more relevant than general computer vision experience. The final output will be a written report with recommendations against a defined set of review criteria. Two rounds of follow-up clarification are included after the initial report.

AI Trading Robot for MetaTrader 5 – AI Model & Trading Dashboard

I need an experienced AI/ML developer to help build an AI-based trading robot for MetaTrader 5. The main idea is to use historical MT5 market data and technical indicators to train an AI model that can evaluate intraday market movements and generate trading insights. The actual trade execution will be handled through MetaTrader 5. Along with the trading robot, I also want an independent software/dashboard where I can monitor the model, trading activity, signals and overall performance. The project will involve working with a large amount of historical MT5 data, preparing the data for training, building the AI model, testing its predictions and connecting the final system with MT5. I'm looking for someone who can understand the existing requirements, suggest practical improvements and build the system in a clean and reliable way.

Python / Machine Learning Developer for Sports Prediction Model

I have an existing Python-based Serie A soccer prediction model and I'm looking for someone who can help me improve and automate it. The model is already working, so I don't need someone to build a completely new system. The main work will be reviewing the current code, fixing some issues, improving the modelling and validation, and making the whole system more reliable. Some of the initial work includes improving the hyperparameter tuning, standardizing metrics like Brier score and log loss, setting up proper walk-forward validation, and making sure there is no data leakage. I also want to improve the existing Poisson/Dixon-Coles models, probability calibration, market-odds blending, EV calculations and betting thresholds. Another important part is automation. The longer-term goal is for the system to collect data, update the database, generate predictions, compare them with the market, track results and CLV, run backtests, and test new models against the current production model. I'm looking for someone who can work with the existing codebase and improve it step by step rather than rewriting everything unnecessarily.
