Software engineering for 40+ years. Have run development groups from 4 to 60 people and personally written over 2M lines of code in multiple languages. Specialize in server-side high-volume business applications. Best if involved in all aspects of a project - overall business requirements with management, detailed usage study with departments and users, system architecture design, then detailed design and implementation. Find that this is the most productive way to go from concept to production - any missing or ambiguous requirement can be resolved quickly since the entire context is understood.
