Independent software engineer and technical consultant with 20+ years of experience. I build and maintain enterprise systems, web and mobile applications, and production integrations (POS, ERP, healthcare, finance). In addition to client work, I have experience developing and operating long-running internal products (a POS system and a digital signage/presentation system).
