Hire the Best Data Scientists in Amsterdam, NL

Please also see my blog: jiddualexander.com I'm a data scientist / analyst and an expert R programmer. I am strong with ggplot (ggplot2 data visualisation) and I am also a Shiny App developer. I can create custom dashboards for your data with intelligent analytics and interactive graphics. I program in R 6 days a week and I am very confident with all aspects of a data analysis project. I use mostly the very powerful packages created by Hadley Wickham (data import, cleaning and tidying (tidyr), manipulation (dplyr), visualisation (ggplot2) and reporting (Shiny)). The list of online certificates (below) is a good indication of the focus of my skills. To understand the power of these tools for creating dashboards I suggest you take a look at RStudio's Shiny gallery (shiny.rstudio.com/gallery/). I have participated in the Master R Developer Workshop by RStudio, thaught by no other than Hadley Wickham himself. My expert knowledge in R extends to high quality functional programming, package building, meta-programming and more. I have a Master Degree in Theoretical Physics from Sussex University (UK) and very strong understanding of analytics and machine learning, including neural networks (which I studied at Uni), support Vector machines, RandomForest, Principal Component Analysis (PCA) and much more. Including the tools to train machine learning models I also have a fundamental understanding and set of tools to apply the correct models for specific situations.

I am a data analyst, data scientist and machine learning programmer with about 20 years experience working in the data-field. I work with tools like Python, SQL, R, Excel, Excel VBA, Power BI, Azure Synapse I am familiar with all the regular libraries like scikit-learn, numpy, pandas, matplotlib, tensorflow, R shiny, Caret, ggplot, dplyr, lubridate etc. With my econometrical background I am good in statistics and find it also important to present my work visually and textually in an attractive and understandable way.

I'm an AI Engineer passionate about building and deploying innovative solutions. I specialize in deep learning – from designing and training models (including transformers and CNNs) to optimizing them for real-world performance. I've built everything from AI-driven art generation tools (backed by research and a published paper on GANs) to automated trading algorithms using deep reinforcement learning. I'm comfortable taking projects from concept to deployment, including data processing, model training (from scratch or fine-tuning), and infrastructure setup (both on-premise and in the cloud). I'm also experienced with techniques like quantization (TensorRT) to reduce latency and improve efficiency. I enjoy collaborating with clients to understand their challenges and deliver impactful results. Let's discuss how I can help bring your AI vision to life! (And yes, I'm always up for a coffee to chat about your project.)

My background is in information science and applied machine learning — how knowledge is organised, retrieved, and evaluated. I build retrieval and NLP systems with a focus on structured evaluation, deliberate model scoping, and architectures that remain maintainable after handover. What I typically take on: 🔍 Retrieval systems, evaluated rigorously — chunking strategy, embedding selection, reranking, and measurable retrieval quality before any generation step. 🗂 Structured extraction — turning unstructured text into clean, typed data through schema design, classification, and ground-truth-based evaluation. 🔗 Knowledge representation — indexes, ontologies, and metadata that make information findable for the right reasons, not just by surface similarity. Every engagement includes evaluation infrastructure, documentation, and a working handover. Portfolio and prior work below.
