Emma's story

Software Developer at ThoughtWorks on £32,000

Before Makers I trained as a historian of gender, education and technology. Coding is like craft-making, figuring out puzzles, even experimenting in the kitchen, activities I enjoy doing but would never have thought could be related to software engineering. It requires teamwork, imaginative thinking, and curiosity. It’s language-learning, problem-solving and communication all in one - I love it and because of that I got into coding.

Code sample

            require 'set'
            
            class Cell
            
              attr_reader :slices, :value
            
              def initialize(value)
                @value = value.to_i
                @slices = []
              end
            
              def add_slice(slice)
                @slices << slice
              end
            
              def solved?
                @value && @value != 0
              end
            
              def to_s
                return '_' unless solved?
                @value.to_s
              end
            
              def solve!
                return if solved?
                assume(candidates.first) if candidates.length == 1
              end
            
              def assume(value)
                @value = value
              end
            
              def candidates
                (1..9).to_set.subtract(neighbours)
              end
            
              def neighbours
                @slices.flatten.map(&:value).inject(Set.new) {|set, digit| set << digit}.delete(0)
              end
            
            end
            

I chose to present this code because I am proud of the small, clean methods each with obvious names and clear responsibility.
