Langr Software Solutions, Inc. offers software training, consulting, mentoring, coaching, staffing, and development services. Services are provided primarily by Jeff Langr (me) but also in conjunction with a number of peers in the agile software development world. Langr Software Solutions was created in 2003 as a sole proprietorship, and was incorporated in 2013.

I have delivered services in the United States, South America, Europe, and Asia, and can help you no matter where you are.

Jeff Langr

I am a veteran software developer with over a third-century of experience. I’ve written five books on software development:

I also contributed two chapters to Uncle Bob’s (Robert C. Martin’s) bestselling book, Clean Code (Prentice Hall, 2008).

I am ecstatic to be a member of the technical advisory board for the Pragmatic Bookshelf.

I’ve written 90+ articles that appear in publications including PragPub, Software Development magazine (now part of Dr. Dobbs), Informit.com, Ron Jeffries’ XProgramming.com site, Gamelan.com, Developer.com and C/C++ Users Journal. I’ve spoken at various user groups and conferences, including OOPSLA (2001), SD East (2001), Cingular Wave (2001), Agile Developers Conference (2004), Agile 2007, the World Congress for Business Analysts (2007), Agile 2011, and AgileDC (2011). I also provided the keynote for the first-ever technical conference at Marion Correctional Institute in 2010.

I have considerable experience in Clojure, Java/J2EE, C#/.NET, large scale C++, object-oriented design, test-driven development (TDD), behavior-driven development (BDD), agile software development, and extreme programming (XP).

I have worked for several Fortune 500 companies, including Marriott, MCI, and Sabre. I was an Object Mentor consultant from 2000 through 2002, where I had the opportunity to work with and learn from many of the finest people in the industry. I have supplied expertise for customers in a broad array of industries, including government, insurance, airlines, telecommunications, retail, medical, software, research, religion, manufacturing, and finance. I’ve helped design and develop many successful systems, ranging in size from two-week deployed efforts to multi-million lines-of-code systems.

I have created and taught courses to hundreds of students at dozens of customers, including American Airlines, CarFax, CheckFree, eBay, Enron, Ford, Gordon Food Service, Grange Insurance, HP, Key Bank, Nationwide, Sabre, Stanford Linear Accelerator Center, Verizon, the Veteran’s Administration, and Visa. I taught a Java development course at Colorado Technical University, where I also presented an agile seminar to doctoral candidates.

I’ve provided subcontracting services for some great folks in the industry, including James Grenning at Wingman Software, LeanDog, Industrial Logic, SolutionsIQ, and ProTech.

I love doing this stuff–I hope it shows!
