Meet Vladyslav ✨

An AI/ML Engineer and LLM specialist with three years of experience building multi-agent systems, RLHF training pipelines, and AI-driven automation workflows. Vladyslav focuses on the intelligence layer of AI products, working with prompt engineering, model evaluation, adversarial testing, and agent orchestration to make LLMs perform reliably in production environments.

His work includes designing multi-agent systems using Google ADK and LangGraph, developing adversarial prompt datasets that improved LLM robustness by identifying hallucinations and reasoning failures, and building probabilistic simulation engines for game mathematics. He brings a strong analytical foundation with hands-on experience in machine learning, NLP, data analysis, and large-scale statistical modeling.

Vladyslav is backed by certifications from Stanford, DeepLearning.AI, and DataCamp covering supervised learning, NLP, CNNs, and prompt engineering. He works with Python, LangChain, Hugging Face, TensorFlow, and GCP, combining research-level AI understanding with practical engineering to ship systems that actually work.

If your product needs someone who can design intelligent agent systems, optimize LLM behavior, and build evaluation pipelines that keep AI quality high at scale, Vladyslav is the engineer who makes your AI smarter 🚀
