I act as a Digital-Physical Systems Architect(Engineer), bridging the high-resolution gap between computational simulation and 3-micron physical execution. My workflow is governed by a Zero-Error Philosophy: I do not provide "attempts"; I engineer solved outcomes.
Strategic References
Rolls-Royce Marine: Manufacturing Lead for 5-meter propulsion assemblies and thrusters. Optimized high-speed kinematics and manual G-code for heavy industrial maritime systems.
• Maersk & Siemens: Tier 1 Liaison managing strategic governance, data traceability,
and operational integration for global infrastructure.
• Danish Government & PET: Handled sensitive infrastructure projects requiring absolute
operational security and zero-error data frameworks.
• Defense & MedTech: Specialized in thermal management for Defense HVAC and ISO 13485
compliant manufacturing for the Japanese medical market (3-micron tolerances).
The Integrated Execution Loop
For Tier 1 government, defense, and MedTech (ISO 13485, SMACNA) projects, failure is a result of fragmented data. I eliminate this friction by integrating the entire loop:
• Virtual Validation (CFD & FEA): High-fidelity simulation of fluid-to-air heat transfer
(STAR-CCM+, nanoFluidX) and structural integrity (Simcenter Nastran).
I validate the physics before a single resource is committed.
• Design for Manufacturing (DFM): Translating complex geometry into flawless CAD/CAM
architecture (NX, SolidWorks or any preferred file format). I ensure that the 3D model,
technical drawings, and G-code are a perfectly synchronized loop.
• High-Precision Production: Expert-level mastery of 5-Axis Milling and Swiss-Type Turning
(Citizen/Nakamura-Tome, Fanuc/robotics) for exotic materials like Titanium and PEEK.
Strategic Governance & Value
My background includes designing data traceability frameworks for PET, the Danish Government, and leading manufacturing for Rolls-Royce Marine (5-meter propulsion assemblies). I specialize in Operational Turnaround, using first-principles logic to solve engineering friction that traditional vendors miss.
The Zero-Error Guarantee
I do not accept payment for unstable or unverified solutions. I prioritize Fixed-Price, Solution-Based contracts because my value is measured by the elimination of technical risk.
Note on Availability: To maintain 100% fidelity and precision tolerances, I accept only a limited number of high-stakes strategic partnerships per year.

I build and evaluate production AI agents for real business workflows. I work from ambiguous requirements through architecture, implementation, evaluation, deployment, observability, and handoff.
Recent delivery: I completed Kinetix Mentor through a $5,600 / 140-hour Upwork engagement. It is a deployed WhatsApp AI platform combining Gemini models, LangGraph orchestration, Pinecone RAG, PostgreSQL memory, multimodal processing with GCS, Stripe subscriptions, external research tools, LangSmith tracing, FastAPI, and Docker. The client gave the project 5 stars and described me as “a complete professional who gets the job done.”
I am now turning Kinetix into a measurable Agent Evaluation system. Current work includes:
• Versioned JSONL evaluation datasets and repeatable model runners
• Deterministic scoring for tool selection, routing, arguments, security, and response contracts
• Repeated live-model evaluation instead of one-off testing
• Trace-driven failure analysis and targeted regression testing
• Separation of scorer defects, agent defects, and infrastructure failures
The first router baseline evaluated 30 repeated model runs, uncovered both measurement defects and genuine agent failures, and produced a 17/17 passing targeted regression after fixes.
I can help you:
• Build or repair LangGraph, RAG, and tool-using AI agents
• Create evaluation datasets, behavioral scorers, and regression suites
• Diagnose production traces and improve reliability, quality, latency, and cost
• Integrate FastAPI, PostgreSQL, vector databases, webhooks, payments, and external APIs
• Turn an AI prototype into a deployed, observable workflow with clear documentation and handoff
Before freelancing, I worked in ByteDance’s international business, building data-driven systems and translating ambiguous business problems into measurable technical outcomes.
Best fit: AI Agent and RAG systems, LLM evaluation, existing AI product improvements, reliability audits, and production integrations.
Send me your workflow, current architecture, failure examples, and success criteria. I’ll propose a concrete first milestone.

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
