I have 15 years of experience developing software for scaling startups and delivering large, confidential projects for corporate clients. Recently, I've been working on the architecture of the world's largest distributed trading systems, which support more than $7 trillion in assets under management (AUM).

My professional work is conducted using corporate accounts and company-managed version control, so you won't find confidential, work-related projects in my personal GitHub portfolio.

For professional experience, see my LinkedIn profile.

My public repositories showcase hands-on work in LLM tooling and AI-powered software, alongside open-source contributions such as Janito, backend engineering with Java and Spring Boot, distributed FinTech components, API and contract testing, and Python-based automation and data analysis.
