What I'm looking for

I seek roles building backend and AI-driven systems in e-commerce or data-focused teams, with opportunities to ship production services, work on generative AI/RAG, and grow technically within Agile environments.

I am a full-stack engineer with hands-on experience building backend services in C#/.NET and VTEX IO modules, focused on reliability and performance for large-scale storefronts. I have delivered production-ready features that improved API reliability, reduced latency, and streamlined deployment workflows for enterprise clients.

My generative AI work includes revamping RAG pipelines, fine-tuning LLaMA models with FAISS/Chroma embeddings, and developing a multimodal resume-analysis chatbot that significantly reduced manual screening. I combine practical ML engineering with web and automation skills to produce measurable business outcomes.

I enjoy solving backend and automation problems for e-commerce and data-driven products, and I bring a track record of speeding onboarding, increasing engagement, and shipping components under Agile sprints.
