About Jonathan J.

I am looking for available career opportunities in software engineering or business management. Highly versatile engineer with a rare combination of experience in risk management, business, operations, and data analysis & data science, with a focus on software development. Quick learner and early adopter who thrives in fast-paced environments focused on leading edge technologies. Reputation for quickly assessing business needs to develop original, creative solutions. Well managed, I demand time boxed, succinct, fast-flowing conversations, that actually build out a business domain or domains.Do you need a leader with the backbone to drive forward and operate in an ambiguous landscape, sans the ego and associated toxicities that demoralize modern technology work spaces? Do you need an engineer who understands hybrid cloud and on premise architecture, building and delivering secure comprehensive solutions? Do you currently employee engineers that demand self healing designs, high resiliency, redundant backups, and highly available solutions? Are you looking for an engineer who understands the challenges of large scale architecture? Are you currently looking to update from outdated solutions to modern technology? Did you mistakenly over bet on new college hires who don’t understand corporate infrastructure or security postures, proxies, intranet, networking, operating over a VPN, customer entitlements & corporate authentication mechanisms? Are you ready to hire a professional, well versed in working in a highly regulated industry? Are you simply looking for a leader with the emotional intelligence to “right your ship?”Good news! I have an inbox!
