Web front ends built on modern JavaScript frameworks like React and NextJS balance client and server side rendering for blazing fast response time. Well designed REST APIs provide access to cloud native services like search and pub-sub . Mediation by an ESB is the most common design pattern to bring together cloud and traditional back end services such as ERPs and CRMs.
Agile and Waterfall methodologies are applied depending on the client circumstances. Some applications cannot be launched as an MVP and requirements must be fully fleshed out before signoff and development.
Modern DevOps are leveraged using the clients already in place tooling or best practices implemented when needed.
