Need an expert?

Software Development Consulting

Hi, my name is Dathan Guiley (

I am a tech veteran with 20 years of professional experience developing and managing at top internet companies including Amazon, Netflix, Yahoo, and Overstock.

For the last few years I have been a freelance expert stepping into companies of all sizes and pushing them forward.  This includes projects from getting a startup launched with the right technology to working with an enterprise migrating to microservices.

I am full stack, focusing on Java based technologies (Scala, Groovy, Spring), AngularJS, HTML5, Web Services, Micro Services,  relational and NoSql databases (Couchbase, Cassandra), Big Data (Spark, Storm, HDFS), Queueing (JMS, AMQ, Kafka), AWS, BDD, etc. etc.

There are many reasons to turn to an expert when developing software.

  • If you want to start your project off right.
  • If you have a gap in your development team.
  • If you want to make your development team more effective.
  • If your project is at risk.
  • If your project is scaling.
  • If you need coding done right (understandable, testable, and maintainable)
  • If you need help hiring (job descriptions, interviewing).
  • If you need assurance you are on the right track.
  • If your project is keeping you up at night.

I am unique due to my depth of experience combined with my availability to do this kind of client work.  I am the primary contact for all PowerUp Consulting work and own the project until your team can take it on.

Contact me.  I am happy to talk about your project and give you my initial thoughts.
