About Me

Computer science graduate and GenAI enthusiast with over 1.5 year of practical interactions with LLMs, experience in building an enterprise AI Agentic framework in MVP version, supporting many business use-cases getting started with AI Agents. Seeking to join a team of innovators and contribute to building state-of-the-art AI technologies.

Agentic AI Development

Built an enterprise AI Agentic framework in MVP version, supporting many business use-cases getting started with AI Agents.

LLM Observability

Leveraged LLM observability tools to monitor and analyze the performance of AI Agents.

Evaluation-Driven Development

Took into account the evaluation metrics to improve the performance of AI Agents.

Deployment

Deployed AI Agents in multiple environments.

My Background

I hold a Bachelor's degree in Computer Science from the Wrocław University of Science and Technology, where I completed CS courses with final GPA 4.56/5.00 and received a grade 'bardzo dobry' (very good) in Diploma.

Final thesis: Intelligent Assistant For Foreigners

This project was aimed to help foreigners in Poland to address challenges such as finding reliable legal information from Temporary Residence Permit application process, Visa, information about Universities, scholarship, schools and health insurance.

I successfully implemented a multi-lingual chatbot applying RAG techniques and using LLMs to answer users' questions.

Skills & Expertise

My technology stack focuses on building AI Agents frameworks and tools to support the development, deployment and monitoring of AI Agents.
