Stephen Sweeney
25+ years building and explaining software systems across aviation, autonomous systems, AI governance, edge computing, search, geospatial platforms, and mobile applications.
Professional focus
I work where architecture, operational authority, and evidence must agree. I am open to principal or staff architecture, technical leadership, governed-autonomy, and senior technical-writing work involving architecture docs, APIs, compliance narratives, and product specifications. Writing samples are at /portfolio.
