Senior Software Developer and Industrial ML Specialist with over 20 years of experience. In my previous role I built mission critical software, including the control systems (SCADA) used to run pipelines, LRT systems, and power plants. Since then I co-founded a startup to build the ML to augment those systems, optimizing industrial systems to reduce power cost and increase throughput, and building failure prediction and detection systems to avoid costly downtime and repairs. My industrial background gives me the experience needed to take software past "production ready" to the five-nine reliability needed when a single glitch can take down a multi-billion dollar production system, or prevent life-saving infrastructure from running in an emergency. As an ML engineer I went back to those same systems with an eye towards the hidden opportunities buried in the raw data. This involved dealing with the complexities of messy real world data such as: missing or malfunctioning instruments, unknown time offsets, unlabelled data, missing logs, and clients with a very different view of the systems. I handled the full lifecycle: data validation and cleaning, feature engineering, model development, application design, and cloud deployment. As a developer I specialize in C/C++, Python, and JavaScript, and am a skilled full-stack developer with strong Linux/Unix system administration skills. My ML specializes in time series, regression, and categorization, but I have built solutions in many other areas including Computer Vision, Reinforcement Learning, and Large Language Models. Having co-founded and led a startup I have a strong eye for evaluating business proposals and focusing on what's needed for a successful MVP. For instance, I know when a particular piece of functionally is critical to the value proposition, and thus needs to be absolutely flawless. And I know which bits of functionality just need to be done as quickly and cheaply as possible so the prototype can get out the door.

Math modeling, PDEs, numerical methods, Python, Rust, Fortran, C++, Julia, Kubernetes, machine learning, parallel programming, high performance computing, data analysis, error analysis. In my master's thesis, I developed a math model to describe the light field in a seaweed farm, wrote an object-oriented Fortran 90 code, parallelized with OpenMP, to solve the resulting PDE using a finite difference algorithm and less computationally expensive asymptotic approximation for multiple discrete scattering events. I performed a detailed error analysis of the two algorithms to determine necessary grid size and applicable conditions for the discrete scattering approximation for a desired level of accuracy. I wrote a Python wrapper using F2PY for the F90 code, and interactive Jupyter widgets to allow highly parallelized simulations to be launched en masse over large parameter spaces from Jupyter notebooks to a remote kubernetes cluster. Other research interests: - Interactive high performance computing - Group decision making - Machine learning - Virtual reality - Interactive data visualization Miscellaneous skills: - Linux - LaTeX - Web development - Image processing / graphic design - Audio/video editing/recording

I am a senior engineer with very good experience in structural analysis. It is almost 10 years since I am working on the freelancer platforms.

AI/ML & Production Systems | Computer Vision, Data Pipelines, Web & Mobile We build AI/ML features that work inside real products, not standalone demos. Our work focuses on integrating machine learning into production systems: mobile apps, backend services, data pipelines, and business workflows. In practice, most AI/ML challenges are not only about training a model. They often come from how data is collected, processed, updated, and used across the system. We help companies turn AI/ML ideas into reliable product functionality by working on: • ML model integration into existing platforms • Computer vision and image/video processing workflows • Data pipelines for processing, inference, and reporting • Real-time and near real-time data handling • Backend APIs for AI-powered features • Web and mobile applications connected to ML logic • Production stabilization and performance optimization We are especially useful when AI works in a prototype but becomes difficult in production: unstable inputs, inconsistent data formats, slow pipelines, integration issues, or model outputs that need to fit real business logic. Our goal is simple: to make AI/ML systems predictable, testable, and usable as part of a larger product.
