About me

I'm a Full Stack Developer with nearly two years of professional experience building SaaS platforms, AI assistants, and data pipelines.

My work spans React, Next.js, Node.js, and Python, from customer-facing interfaces to APIs, databases, and deployment.

I've built tools people discover through search, chatbots that work with domain-specific information, and operational software for managing campaigns and customer conversations.

I enjoy solving the problems between those layers: how data reaches the interface, how a workflow behaves, and how a product performs after deployment.

  • Product development: SaaS platforms, utility tools, dashboards, and CRM systems.
  • AI applications: RAG assistants, LLM integrations, and domain-specific chatbots.
  • Backend engineering: REST APIs, real-time integrations, and data processing.
  • Performance and discovery: Client-side processing, caching, prerendering, and programmatic SEO.
