Designing a feasible AI solution for a unique project can be more difficult than just training a standalone ML model. More often than not, we have to combine several algorithms and models at different data pipeline stages, since you can only reach about 80% accuracy with standard tools. 90% is also doable if you really put your mind to it, but anything close to 99% requires custom solutions and non-trivial approaches. You should account for the existing systems that AI will be integrated with, the real-world data that the algorithm should adapt to, and the way users will interact with the output. Such a solution-focused approach requires a thorough investigation of the client’s goals and IT environment. That way, we can deliver value-driving solutions rather than just unaligned intelligence.

I’ve been working in data and AI for more than 10 years, leading teams and building systems that help businesses actually get value out of their data. At Innowise, I head the Big Data, AI/ML, and Python departments, which means I set direction for our projects but also stay hands-on with architecture, data workflows, and the tough technical decisions. Instead of just listing tools, I’d say my strength is knowing how to choose and combine them to solve real problems. Whether it’s Spark, Databricks, Snowflake, or cloud platforms like AWS and Azure, I treat them as building blocks, not buzzwords. I’ve worked in eCommerce, fintech, gaming, and manufacturing, and what I enjoy most is seeing messy, scattered data turn into clear insights that actually change how a business works. Outside of work, I’m into sports and racing. I like the mix of speed and strategy. I’m also fascinated by physics and technology, especially where they overlap to shape the future of AI and data.
