Grounded in software.Driven by curiosity.

LL.Python at the core.Engineering across the stack.

I’m a Software & AI Engineer with a Computer Science background and 3+ years of experience building backend systems and AI applications. My work connects engineering fundamentals with the possibilities of intelligent systems.

From API integrations and event-driven services to multi-agent applications, I care about how the pieces fit together: architecture, data access, evaluation, and the people using the result.
