Programming is speaking in computer languages
to give computers instructions

What do I do?

I write instructions for computers

I write programs that solve people's problems

I help people solve problems with my technical art

Solving People's Problems

Methodology for solving problems

  • Break problems down into small pieces
  • Solve the small pieces (build functions)
  • Combine pieces into solutions

Over time, patterns emerge.

Software Paterns

Software patterns describe common approaches:

  • Module
  • Factory Pattern
  • Builder Pattern
  • Lazy Initialization
  • Adapter Pattern
  • Inheritance
  • Repository
  • Unit of Work
  • Inversion of Control

Solving problems

Often times I use the Scientific Method to solve problems

Constantly learning

Software is changing really fast.

I'm constantly learning new technology.

Users generally have similar problems

so there are very stable things too.

I love that I get to keep learning.

Programming is a team sport

I work with:

  • Graphic Designer
  • Network Engineer
  • Project Manager
