I am building a Windows-based computer-vision system that pulls images and related text from PDF and XML sources, then trains a deep-learning model to recognise those images with high accuracy. Everything happens in Python, so the entire training and evaluation pipeline—including data loaders, augmentation, model definition, loss functions, metrics, and experiment tracking—must be written in clean, modular Python code that runs smoothly on a local workstation or GPU server. You will connect preprocessing routines to the raw documents, structure datasets for efficient loading, and iterate through model architectures (CNNs, transformers or other modern backbones). Precise reporting of training curves, confusion matrices, and F1/accuracy scores is essential; the project’s s...
I have a complete purchase-history dataset ready to go and I want to turn it into actionable customer segments. The single objective is clear: identify distinct target customer groups so I can market to them more effectively. The analysis must surface three core insights: • Which customers are truly high-value • Who buys most frequently • Who shows signs of churning You’re free to choose the right statistical or machine-learning approach—RFM scoring, K-means, hierarchical clustering, or a hybrid model—as long as it fits the data. I’ll supply the raw CSV and a short data dictionary; you return: 1. A cleaned, well-documented dataset with the segment labels appended 2. A concise notebook or script (Python, R, or SQL-based) that reproduces th...

I’m driving a couple of AI initiatives and need a developer who is equally comfortable fine-tuning Claude, ChatGPT and Gemini as they are building custom projects across multiple products under active development. Collaboration matters to us: plan on spending two full days each week in our Delhi or Noida office/co-working space so we can whiteboard, pair-program and push code together. On the remaining days you can work remotely, but I still expect roughly four focused hours of contribution daily to keep momentum steady. Typical output will include clean, reproducible training scripts, fine-tuned checkpoints, inference APIs and concise documentation so the rest of the engineering team can plug your work straight into production. If this cadence and skill mix excite you, let me kno...
I need a fully-functional web application that acts as an AI voice assistant for farmers. The core job is to make disease detection effortless: a user should be able to describe plant symptoms (or speak them) and immediately receive an accurate diagnosis, possible causes and treatment steps. Beyond that primary task, I would like the same interface to offer crop recommendations and general farming advice so the system feels like a single, knowledgeable companion rather than three separate tools. The web app must accept both voice and typed questions, switching smoothly between the two without page reloads. Under the hood you are free to combine the machine-learning and deep-learning frameworks you prefer—TensorFlow, PyTorch, scikit-learn, FastAPI, Flask, or any stack you are co...

I need to roll out an AI enablement program that measurably improves our operational efficiency. The engagement starts with a deep dive into our current workflows so we can uncover bottlenecks and quantify the gains an intelligent solution could bring. Once the baseline is clear, the next step is to design a practical roadmap that aligns technical effort with the highest-impact opportunities. I am open to the full spectrum of AI approaches—whether that ends up being a machine-learning model to predict demand, natural-language processing to streamline internal knowledge access, or robotic process automation to remove repetitive back-office tasks. The key criterion is that every recommendation can be tied to a clear efficiency metric and a realistic implementation timeline. Deliv...
