I Enable Early-Career Enterprise Software Engineers to Continuously Improve

My passion is taking a metaphysical approach to software engineering: what is the nature of the collaborative game that we continuously play, and are there better, more contextually-aware ways to play that game?

By day I lead a team tasked with taking a first-principles-centric approach to intentionally enabling programming language usage at the largest bank in the United States.

By night I write and teach my way through a masterclass in software engineering and architecture targeting early-career software engineers working in large-scale enterprise technology organizations.

What is the primary goal?

To win the game. More seriously: to get 1% better every day at providing business value through software.

Who am I?

I'm a 22-year veteran of the enterprise software industry. I've played almost every role I can imagine:

  • Software Engineer
  • Software Architect
  • Technical Lead
  • Engineering Manager
  • Consultant
  • Product Manager
  • Field CTO
  • Developer Advocate
  • Conference Speaker
  • Author
  • Technical Trainer
  • Technical Marketer
  • Site Reliability Engineer
  • Desktop Support Specialist

I've worked at Fortune 500 companies, a tenacious teal cloud startup, and a not-for-profit children's hospital. I've written a book, and I've hosted a podcast. I've learned a lot along the way, including many things I wish I'd known when I first got started. And so now I want to pass those learnings on to you, especially if you've only just begun your career.

Presentations

Functional SOLID

Robert Martin assembled the SOLID family of principles to provide a useful guide to help us create object-oriented software designs that were resilient in the face of change. In recent years, the need to write highly-concurrent software in order to leverage increasingly ubiquitous multicore architectures, as well as general interest in more effectively controlling complexity in large software designs, has driven a renewed interest in the functional programming paradigm. Given the apparent similarity in their goals, “What is the intersection of SOLID with functional programming?” is a natural question to ask.

Programming with Immutability

For much of the last two years I've delivered a two-part series at NFJS shows entitled “Effective Java Reloaded.” For all pracical purposes, it is an ala carte style rehash of the book Effective Java, written by Josh Bloch. One of my favorite parts of the discussion is of Item #15, which tells us to “Minimize Mutability.” If we turn this inside out, we're actually saying that we want to MAXIMIZE IMMUTABILITY. When we do this, we reap many benefits, such as code that is easier to reason about and that is inherently thread-safe. This can carry us a long way in the direction of program correctness and decreased complexity. However, when we start to program with immutability, several major questions arise.

Critical Thinking in Software Engineering, Part I: Lecture

No matter where you slice software engineering:

  • architecture
  • technology selection
  • process
  • etc.

The root cause of many, if not most problems, is the common absence of critical thinking in how we approach decision making. Instead of thinking critically about our engineering decisions, we often follow a Cargo Cult mentality or blindly follow the pronouncements of the Blowhard Jamboree. The end results all too often include suboptimal productivity, excessive spending, poor quality and cancelled projects.

When we think instead critically about a component of software engineering, we take it apart. We discard our presuppositions. We challenge tradition. We gather our own evidence. We question everything.

Effective Java Reloaded

Even with the recent explosion in alternative languages for the JVM, the vast majority of us are still writing code in “Java the language” in order to put bread on the table. Proper craftsmanship demands that we write the best Java code that we can possibly write. Fortunately we have a guide in Joshua Bloch's Effective Java.

Vagrant: Virtualized Development Environments Made Simple

Have you ever wished that your local development sandbox could look exactly like production, but you've got a mismatch between your local OS and your production OS? And what about the age old “it works on my machine” excuse that quite often stems from differences between developer sandboxes? Many have turned to virtualization, creating a machine image that can be passed around the team. But who manages the template? How do you keep things in sync?

In this session, we'll explore Vagrant (http://www.vagrantup.com), an open source tool that allows you to easily create and manage virtual development environments that can be provisioned on demand and “thrown away” when no longer needed.

Effective Java Reloaded, Part II: Hello, Project Coin!

Even with the recent explosion in alternative languages for the JVM, the vast majority of us are still writing code in “Java the language” in order to put bread on the table. Proper craftsmanship demands that we write the best Java code that we can possibly write. Fortunately we have a guide in Joshua Bloch's Effective Java.

Code Archaeology

Feature requests are steadily pouring in, but the team cannot respond to them. They are paralyzed. The codebase on which the company has “bet the business” is simply too hard to change. It's your job to clean up the mess and get things rolling again. Where do you begin? Your first task is to get the lay of the land by applying a family of techniques we'll call “Code Archaeology.”
