Greg Leman -

I'm a software development leader with decades of experience. I've worked in large enterprises, startups, and small businesses. From a team lead at Electronic Data Systems to a Senior Director at Oracle, I've seen the inside of large organizations. I've also been a serial entrepreneur. I was a founder of Powerhouse Systems, CEO of Maptronix, and CEO of Metagenix. I'm a techie that is equally comfortable with leading an organization as well as writing code.

Articles / Talks / Patents

Read my blog articles to find out more about my software development philosophy.

Patent #6,604,110: "Automated software code generation from a metadata-based repository" is the patent from MetaRecon. This was a data profiling system that analysed raw data to reverse engineer relationships and automatically generated ETL jobs to populate a data warehouse. This product became part of IBM's Infospehere.

Websites

Here are some websites I've built and maintained:

These projects showcase different aspects of web development including responsive design, performance optimization, and integration with various backend systems and APIs. They're all written in PHP and use Laravel as the framework.

GitHub

Yes, my GitHub is kind of sparse. I spent most of my career building startups or leading in global organizations, which doesn't leave a lot of time for open source projects. This doesn't mean I haven't written a ton of code. My LoC is in the millions. It's just not public. Heck, most of it didn't even use GitHub at all.

GitHub Profile

Featured repositories:

  • Laravel Tools - A utility package for Laravel applications, which includes natural language to SQL processing. Never write SQL or Eloquent again!

Career Highlights

My career spans several decades in software development and leadership roles across various organizations:

  • Senior Director - Oracle Corporation
    Led an organization responsible for building and maintaining custom tools. Also ran the global sales data quality organization, including standing up a service center.
  • CEO - Metagenix
    Founded and led data profiling software company eventually acquired by IBM. This is the product that became ProfileStage.
  • Products Division Manager - Tiburon
    Tiburon acquired Maptronix, and I rose to head the product development group. Tiburon was a leading vendor in systems for law enforcement, fire, and EMS.
  • CEO - Maptronix
    Founded a startup that created the first real time mapping system for 911 call centers. Not such a big deal today, but in the early 1990s this was cutting edge.
  • Team Lead - Electronic Data Systems (EDS) / GeoBased Systems
    Developer in the Geographic Information Systems space.
  • Founder - Powerhouse Systems
    Built what might have been the first CRM. It ran on laptops and communicated via modem in a peer-to-peer network to share sales forecasts.

Throughout my career, I've successfully balanced technical expertise with business leadership, delivering innovative solutions while growing organizations.
