About

From Code to Architecture

I began as a web developer - writing production code, debugging client-facing systems, and understanding what makes software reliable at scale. That foundation didn't fade; it became the lens through which I evaluate every technical decision.

My path followed a steady upward arc: in a mid-sized agency, I grew from developer to team lead - managing engineers, running estimations, and presenting solutions to clients. In a larger software company, I stepped into technical consulting - analyzing feature requirements, integrating APIs, and coordinating across QA, DevOps, and commercial teams.

Today I operate at the intersection of engineering execution and solution design - owning projects end-to-end, bridging technical and business stakeholders, and steadily expanding toward solutions architecture.
