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. Skills & tools: Languages: Python (full-stack), SQL (MySQL/Postgres), C++, R, MATLAB/Octave, NetLogo, Unix/shell Python stack: TensorFlow, Keras, PyTorch, scikit-learn, Pandas, SciPy, NumPy, Matplotlib, Bokeh, Streamlit, Flask, Django, Jupyter Infrastructure: big data, HPC, GPU acceleration, cloud compute Visualisation: d3.js, Tableau, Streamlit, Bokeh, Matplotlib Methods: ML (classifiers, CNN/RNN deep learning, deployment) · LLMs (NLP, RAG, agentic workflows, automation) · reinforcement learning · agent-based & dynamical-systems modelling · network analysis & inference · dimensionality reduction (PCA, t-SNE, kernel) · structural equation models & causal inference · numerical optimisation (simulated annealing, basin hopping) · full-stack software development · data visualisation

I’m a Senior NLP Engineer / Tech Lead with 8+ years of experience building production-grade machine learning systems, with a strong focus on LLMs and natural language processing. Currently, I lead the development of a smart assistant for a large e-commerce and food delivery platform, where I design and implement end-to-end LLM pipelines — from query understanding and retrieval to response generation and post-processing. My core expertise includes: Building and optimizing RAG pipelines (retrieval, reranking, grounding) Fine-tuning LLMs using PEFT methods (LoRA, adapters) Designing scalable LLM-powered features for real-world products Improving relevance, reducing hallucinations, and aligning outputs with business goals Prompt engineering and evaluation (including custom metrics and error analysis) I’ve worked on both B2C and B2B applications, and I understand how to balance quality, latency, and cost when deploying LLM systems in production. I’m especially interested in projects involving: LLM-based assistants and copilots Search and recommendation systems Document processing and information extraction End-to-end ML system design.

Hello! My name is Mike, and I’ve been involved in design for 15 years (OMG). In 2017, I became a co-founder of League Design Agency — the team of engineers with the artist's soul! We admire those who create value for consumers and change the world with their products and services. Are you one of them? We have developed a step-by-step design process with which we'll identify your business's core vision & values to implement them in your unique design! Let me introduce our design teams led by industry-recognized design team leaders: 📱 UI/UX design — aesthetic and efficient to use When creating a UI/UX design, we answer two questions: Why do people download the app? Why will they love the app? We define a "key feature" and build the rest of the App around it. And to make people truly love it, we came up with "a special design idea" that makes the App unique visually and in terms of user experience. 👀 Brand identity design — unique and memorable A remarkable and unique brand image is what we do. We thoroughly explore your vision as a result must match it. We study your customers so that every design element resonates with them. We analyze your competitors to understand your position and know which direction to go to be different and better. 💡 Brand strategy — consistent and well-thought-out You probably have many questions about your brand: what tone does your brand speak? What advantage to choose as the main one to stand out? Where is your target audience, and how to reach their minds? Is your brand serious or fun? We’ve developed a technology that will help you find the answer to all these questions and make your life easier because with a brand strategy, you understand where to go for your brand to scale and grow. 🖥 Web design — modern and engaging The primary purpose of a website is to Sell! Besides selling products, it can attract new employees, suppliers, and investors. For this to happen, each of them must understand the value. With our technology, we determine the USP (Unique Selling Proposition), RTB (Reasons To Believe), and more to broadcast it through the visually appealing and unique website. If we briefly describe our path and achievements in a few figures, then League Design Agency is: 🔳Team: 52 🔳Countries: 40 (USA, UK, Canada, Australia, Germany, UAE, etc); 🔳Projects: 376 🔳Awards: 59 → Zenia app — "App of the Day" featured by Apple → Tarilka — Top of Behance (the highest award of the world's largest creative network); → Holly app — attracted investment and successfully launched the market (find on App Store); → Holly — TOP-100 best landing pages featured by Web-design community; → Geo Protocol — passed the first two rounds of investment and launched unique technology to the market; → 16 Behance awards; → 23 awards from The Ukrainian Creative Awards; → 6 Clutch awards.
