Cloud and Application Modernization
Technical articles and architecture insights on cloud migration, modernization strategy, legacy transformation and enterprise IT.
Everyone is building “agents” now. But ask five engineers what an agent actually is and you’ll get six answers. I’ve spent the last year working on agentic systems — from industrial diagnostic agents to workflow …
The hardest part of building software is not writing code. It’s understanding what to build. I’ve facilitated dozens of workshops with enterprise teams — some building new products, some untangling decades of legacy processes. …
