Full-stack and data engineer. I build useful products end to end: polished web interfaces, reliable backends, data workflows, and AI-assisted features.
I adapt to the problem rather than force it into one stack. My work includes web applications, browser extensions, Ruby services, Python data engineering, and developer tooling.
- Product engineering: React, Next.js, TypeScript, Node.js, REST and GraphQL APIs
- Data engineering: Python, ETL pipelines, scraping, automation, PostgreSQL, Redis
- Other stacks: Ruby (Rails) and browser-extension development
- AI: LLM features, RAG, and agent workflows used to solve real product and engineering problems
