What I'm looking for

I'm looking for part-time remote contracts where I can build production ML and LLM systems end-to-end, from modeling and evaluation through deployment, monitoring, and measurable product impact.

At Avito.Tech, I built and deployed ML systems that generated $150k–$300k in monthly revenue, reduced image manipulation fraud by 70%, and improved service satisfaction by 17%.

I engineered an LLM-powered buyer assistant and real-time RAG pipeline that increased CTR by 12%, alongside systems for tariff evasion, moderation evasion, credit-offer abuse, vehicle attribute extraction, and cross-category content leakage. I also mentored ML interns through production projects to independent ownership.

At Plata Card / MX Credit Systems, I develop scoring and uplift models end-to-end, including feature engineering, validation, deployment, monitoring, drift detection, and retraining pipelines.
