Case Studies

Here are some examples of projects I have delivered recently.

Agentic workflow system

Connecting a LLM-based AI agent to a toolset that allows it to perform real-world tasks within a specific problem domain, backed up by an internal knowledge base. System is built to support working with any 3rd party model provider, avoiding vendor lock-in. It also includes human supervision capabilities to avoid relying on AI blindly.

Impact: Automation of the routine tasks allowed to reduce the completion time to minutes instead of hours.

Key tech: Python, Postgresql, RabbitMQ, LLM API integrations, RAG pipeline.

Migration from monolith to microservice architecture

I defined the change roadmap and led the team performing a split of an existing monolith system into microservices which then got deployed within a 3rd party microservice architecture.

Impact: The company integrated its product into a partner's ecosystem, unlocking additional market opportunities, which led to 10x increase in daily user count.

Key tech: Node.js, Java, MongoDB, Kubernetes.

Stock market volatility tracker

A website and the underlying backend system that tracks high-volatility events in the U.S. stock market and sends automated notification emails to mailing list subscribers.

Impact: Added value allowed to grow the mailing list with a new offering.

Key tech: Python, SQLite, stock market and email API integrations, Polars and NumPy for data processing.
