I turn tangled data and hard modelling problems into things you can actually use — a working model, a deployed app, a clear answer to a question that mattered enough to pay someone to get right. I hold a PhD in Complexity Sciences and a first in Theoretical Physics, and I've spent ~15 years as a researcher and consultant building this stuff for real. Most of that work has been across fields that don't usually talk to each other: critical-care medicine, theoretical ecology, economics, education, and industry. That range isn't a gimmick — the same handful of methods (machine learning, agent-based simulation, network analysis, optimisation) keeps showing up in different disguises, and having applied them in genuinely different settings means I recognise which one your problem actually needs, rather than reaching for whatever's fashionable this quarter. A few concrete things, so this isn't just adjectives: I built and deployed a Flask decision-support app for ICU discharge that came out of a machine-learning study (published in BMJ Open). I've written agent-based models of illegal fishing and GPU-accelerated simulations with large speed-ups over the naive version. I've done reinforcement-learning and optimisation for allocating people at organisational scale, control software for off-grid sanitation hardware, and Streamlit data tools for public-good projects. My research has appeared as first-author work in Nature Communications, PNAS, and BMJ Open. Two things I'm reliably good at: picking up an unfamiliar technique and getting it working quickly, and explaining a complicated result to the people who have to act on it without dumbing it down. I work in full-stack Python and am comfortable across the whole pipeline — extraction and cleaning, exploratory analysis, model building, and getting it deployed somewhere people can click it. I run a small consultancy, Rusty Data, focused on helping organisations get value out of data they're already sitting on. If you've got a modelling problem, a pile of data you suspect is useful, or an idea you want pressure-tested by someone who'll tell you honestly whether it'll work — send me a message with a bit of detail and I'll tell you how I'd approach it. How I can help: Build and deploy ML models — classifiers, deep learning (CNN/RNN), predictive tools — end to end, not just a notebook. LLM and agentic work: RAG systems, NLP pipelines, and automation of the tedious analysis you'd rather not do by hand. Simulation and modelling: agent-based models, dynamical systems, and network analysis, including GPU-accelerated versions when speed matters. Optimisation and decision support: numerical optimisation, reinforcement learning, and bespoke apps that turn a model into something a team can use. Data wrangling and exploratory analysis on messy, large, or HPC-scale datasets. Data visualisation and interactive dashboards (d3.js, Tableau, Streamlit, Bokeh) that make a result legible. A second opinion — feasibility reviews, method selection, and clear write-ups for technical or non-technical stakeholders.

I help brands look, feel, and move like themselves through cinematic AI ads, hyperrealistic visuals, and identity-first creative systems. Most creators start with visuals. I start with truth. Before I create anything, I take time to understand: why your brand exists what it stands for what makes it different and what kind of visual world it naturally belongs in That process allows me to create work that feels intentional, emotionally aligned, and recognizable, not generic AI content. What I can help you create: AI cinematic brand ads (15–60 sec) Hyperrealistic AI UGC ads for TikTok / Instagram / Meta Luxury-style AI product & food visuals Character-based brand videos with visual consistency Founder story / launch videos Brand identity starter systems Logo + mini brand direction Visual worlds for brands, products, and campaigns What makes my work different: I don’t just generate content. I help brands uncover a clear visual identity first — then build content from that. That means your visuals are not just “good looking.” They feel like they belong to your brand. This is especially useful if you want: ads that feel more premium a stronger visual presence online consistent AI characters or campaign worlds content that feels branded, not random Selected experience / proof: Built a restaurant brand world over 7 years through concept, visuals, and storytelling Created a supper club concept launch that sold 200 tickets at €65–85 before the event happened Developed character-based AI ad concepts with visual consistency before AI video became mainstream Created a full brand concept document from a single founder conversation Produced a 42-minute cinematic meditation film using AI visuals, script, voice, and sound design Tools I use: AI Video: Seedance 2.0, Kling 3.0, Veo 3.1, Hailuo MiniMax, Runway AI Image: Midjourney, Nano Banana 2.0/Pro, GPT Images 2.0 Editing: CapCut, Premiere Pro Voice: ElevenLabs Music / Sound: Suno Upscaling: Magnific AI, Topaz AI How I work: My best projects usually begin with a short conversation or brief. From there, I can help define: the visual direction the mood / tone the character or environment and the kind of content that fits your brand best Some clients need one strong ad. Others need a full visual world they can keep building on. If you want AI creative that feels premium, cinematic, and true to your brand, I’d be glad to work together.
