// About Me
About Me
I'm a founding engineer and backend lead with 5+ years shipping production systems. Currently at Lyntel, where I've scaled an eSIM platform from 5,000 to 100,000+ users.
I build the backend infrastructure, agent integrations, and internal tooling that keeps things running—including MCP-based systems for automated log analysis and developer workflows. I've worked on AI agent security (prompt injection, data leakage), built APIs optimized for LLM consumption, and created tools that reduced support tickets by 70%.
When I'm not coding, I'm probably reading, listening to music, or playing board games.
