Big Data Sales Jobs

My immediate goal is to develop robust predictive models that can meaningfully inform cardiovascular research and clinical decision-making. I have aggregated multiple datasets—ranging from structured EHR extracts to imaging-derived variables and device telemetry—and now need a data scientist who can turn these raw inputs into clinically relevant risk scores and outcome forecasts. Scope of work • Clean, integrate, and document the disparate datasets I will share (CSV, SQL dump, and optional imaging features in HDF5). • Engineer features, test several algorithms (e.g., gradient boosting, random forests, neural nets), and iterate toward an interpretable solution. • Provide model performance metrics—AUROC, calibration plots, and decision-curve analysis&m...

I am looking for a professional who can take a brief, understand it quickly, and turn it into polished results without endless back-and-forth. Attention to detail, on-time delivery, and clear, proactive communication are non-negotiable because I value a smooth workflow as much as I value great output. The work will touch on typical digital-service tasks—think content, visuals, or campaign assets—so a creative mindset, solid problem-solving skills, and comfort with modern online tools are all important. If you regularly organise yourself with a project-management app, share drafts through a real-time collaboration platform, and automate repetitive steps where it makes sense, you will fit right in. Quality comes first: anything you deliver should be accurate, professionally pac...

I’m sitting on several datasets—a mix of tidy spreadsheets and raw text logs—and I need them transformed into business-ready insights with reliable predictive power. Your first task will be to clean and consolidate this structured and unstructured data in Python using Pandas / NumPy and, where helpful, SQL queries. Once the data pipelines are solid, I’d like an exploratory analysis that highlights key patterns or anomalies before we move into supervised models that forecast the metrics I care about most. For visual communication, every important finding should flow into an interactive Power BI dashboard. I lean on these dashboards to brief non-technical stakeholders, so clarity and drill-down capability matter as much as aesthetic polish. Deliverables • Cle...

I’m looking for an expert who can build a reliable predictive AI model that works with time-series data. I have the raw datasets ready; what I need is the full modeling workflow—from exploratory analysis and feature engineering through training, validation, and clear performance reporting. Key objectives: • Choose the most suitable algorithms (e.g., ARIMA, Prophet, LSTM, or hybrids) and justify the selection. • Handle data preprocessing, missing-value treatment, and scaling so the model remains robust in production. • Deliver reproducible code (Python preferred, using frameworks such as TensorFlow, PyTorch, or scikit-learn) and concise documentation that explains setup, hyperparameters, and retraining steps. • Provide evaluation metrics like MAE, RMSE...

Saya ingin memperdalam keahlian Analisis Data dengan fokus pada Pembelajaran Mesin untuk Pemrosesan Bahasa Alami (NLP). Saya mencari seorang mentor berpengalaman yang dapat membimbing saya secara terstruktur, praktis, dan bertahap hingga saya mampu membangun model NLP sederhana secara mandiri. Lingkup kerja yang saya bayangkan: • Merancang kurikulum mingguan yang mencakup dasar-dasar statistik, pembersihan & vektorisasi teks, word embeddings, model klasik (Naïve Bayes, SVM) hingga model neural network modern seperti LSTM, Transformer, dan BERT. • Mengadakan sesi daring terjadwal (±1–2 jam tiap pertemuan) dengan kombinasi penjelasan konsep dan live coding menggunakan Python, Pandas, scikit-learn, serta PyTorch atau TensorFlow. • Menyiapkan tugas pra...
