Full Stack · Backend · Automation & AI
I build and operate production systems: integrations across communication channels, workflow automation, multi-tenant architectures and LLM-powered pipelines. I work with AI as a daily tool — Claude Code, Cursor and Claude models for development and process automation.
Selected work
Production systems I designed, built and operate — told as engineering case studies.
More shipped systems
Breadth beyond the case studies — systems used daily by multiple teams.

About
I'm a Software Engineer with 2 years building and operating production systems at a digital marketing agency — integrations across communication channels (WhatsApp, TikTok, Twilio, SMTP), n8n automation, multi-tenant architectures and LLM-powered pipelines.
I work AI-native: Claude Code, Cursor and Claude models are part of my daily toolkit, both for writing software and for automating internal processes. I care about systems that are measurable, auditable and honest about their tradeoffs.
