Lazy by Design
My greatest professional quality is laziness.
I hate doing the same thing twice. So I automate it, simplify it, or design it away.
For clients that means systems with fewer moving parts, less manual work and lower maintenance costs for years. Good laziness isn't doing less: it's doing it once.
AI is part of how I work, not a buzzword on top: agentic tools driven by solid architecture and clear specs deliver senior-level quality at a pace that used to take a whole team.
