Let's Chat!About
I'm Yury: 10+ years shipping data projects; I bring a pragmatic, outcomes-first approach and love a good challenge.
I combine technical leadership (setting direction, unblocking teams, making tradeoffs) with implementation (models, data pipelines, deployment, monitoring).
I’m best when the problem is ambiguous, high-impact, and time-sensitive: turning “we should do AI” into a shipped product with measurable results.
How I help
Tech Leadership as a Service
- Act as your fractional CTO / technical lead (part-time, embedded)
- Turn strategy into an execution plan: roadmap, milestones, success metrics
- Make hard calls: build vs buy, architecture, hiring, vendor selection
AI Development
- LLM-powered systems: RAG, vector, document Q&A, internal assistants, workflow agents
- Forecasting, computer vision, NLP, and tabular models
- Rapid prototypes
- Prductionize and integrate into your product (APIs, batch pipelines, dashboards)
Production & MLOps
- Data pipelines with traceability (batch + streaming)
- Reproducible ML workflows (CI/CD, versioning, testing)
- Scalable deployment (cloud/on-prem), cost/perf tuning
- Observability: quality, drift, latency, model performance in production

Projects and Success Stories
A selection of (non-NDA) projects
Anomaly Detection for European Steel Manufacturer
Transforming terabytes of sensor data into actionable insights for a leading European steel manufacturer. I developed machine learning models and real-time dashboards that identified critical furnace issues, saving millions of euros in scrap metal costs and establishing a permanent shop-floor monitoring system.
DailyLauncher
A customizable new‑tab experience that lets you design your own start page with drag‑and‑drop widgets.
Few-Shot Computer Vision for Industrial Wood Grading
Developed a log-face detection system for a leading European timber processor using just 50 training examples. My few-shot learning approach achieved 99%+ accuracy in production, enabling automated quality classification at conveyor speed.
Energy Forecasting for European Steel Manufacturer
Energy consumption forecasting for one of Europe's leading steel manufacturers with AI. In just days, I developed a proof-of-concept that achieved 97% accuracy for day-ahead predictions, enabling optimized electricity trading.
Creative Coding
A collection of generative art pieces exploring geometry, randomness and emergence using Processing.
Rail Cargo Austria Wagon Planning
Digitalising wagon allocation for a pan‑European rail freight leader. I worked with Rail Cargo Austria and research partners to turn a manual planning process into a data‑driven system that anticipates uncertainties in demand and generates optimal wagon plans within minutes.
MARLAnts
A multi‑agent reinforcement learning experiment where simulated ants learn to cooperatively build towers.
Superhuman Multi-Language OCR Engine
Building a custom document scanner outperforming Google Tesseract by 10x in accuracy and 100x in speed across 15 European languages simultaneously.
Restaurant Recommendation Engine
Building a production recommendation system from scratch using Singular Value Decomposition that delivered accurate personalized suggestions from sparse user rating data.
Lego Technic Mars Rover
A fully remote‑controlled 2.7 kg rover built from scratch with 11 motors, pneumatics and realistic functions.
Ricotta and Brunost
A kitchen experiment in making fresh ricotta cheese and turning the leftover whey into sweet brunost.
FAQ
What does 'Fractional CTO' mean? +
It's technical leadership as a service. CTO-level support, part-time: you get a senior technical owner without hiring full-time.
Are you hands-on technical? +
Yes! I build and ship systems: models, pipelines, deployment, monitoring. I also lead teams and make architecture decisions.
Do you work with startups? +
Gladly! Usually at least seed-stage. It has to be a good mutual fit.
What languages and tools do you use? +
Primarily Python and JavaScript/TypeScript (React). I've also shipped production systems in Java, Scala, and C++ when the problem required it.
What are your rates? +
Depends on the type of engagement. My rates are competitive within the EU market, with discounts available for larger projects or retainer arrangements.
