Personal Details

Bio

Originally from the Philadelphia area, Sean has 15+ years of experience solving problems as an IT professional and developer for commercial, non-profit, and federal clients. He's currently a Technical Director at CapTech Consulting -- he *highly* recommends you check them out. Aside from loving his work way too much, there's a good chance he's enjoying being a new dad, sipping great beer, exploring the Arlington area, or singing somewhere. You can find him on Twitter at @sjkilleen or blogging not nearly often enough at SeanKilleen.com. He doesn't bite; say hi!

An Introduction to Akka.NET

Akka.NET is an Actor Model Framework that helps .Net developers create powerful concurrent & distributed applications more easily. The Actor Model is a well-established paradigm for building fault-tolerant and scalable applications that has recently seen a resurgence as distributed and asynchronous systems gain popularity. In this introductory talk, Sean will walk you through the concepts of the actor model, its benefits over traditional approaches, and the basics of how to use Akka.NET to achieve these advantages in your .NET applications.

We need your voice! A guide to putting yourself out there

Have you ever wondered whether you have something to contribute to conversations in the tech industry? YOU TOTALLY DO. In this session, Sean will walk through ways to think about adding your voice to help shape our industry, and what benefits you and your community may gain as a result. He'll share prompts to get you started, and tips to help you follow through. His hope is that you will leave with a renewed conviction that your voice matters, and a pathway to put it out there and feel good about it.

Level up Your Team with Better Technical Interviews

Have you ever been stuck at a whiteboard or solving a brainteaser and thought "there must be a better way"? Good news: there very much is. Technical interviews can be a nightmare for both the interviewer and interviewee. In this talk, Sean walks through his philosophy & practical tips for running technical interviews that are primed for success.

Better Operational Visibility in .NET With Structured Logging

Too many developers underestimate the power that is hidden away in their logs. In this talk, Sean will take us through the "why" of structured logging and the basics of how to attain it via Serilog and Seq, with plenty of examples along the way. You'll learn how to log better, how to search those logs, how to use logs to identify performance issues, and how Sean once substituted good log messages for an entire UI in order to provide business value quickly.

The Dark Art of Just-in-time Tech Talks

I once, to my colleague's chagrin, thought through a tech talk during a drive, wrote slides in an hour, and gave a presentation that was well received and lasted exactly as long as it was scheduled. After doing this a few times (for better and worse), I've picked up some tips along the way on how to deliver a talk no matter how rushed or pressured you may feel. We'll discuss some of my tips, as well as how to know when you're in over your head & adjust.

TeamCity, OctopusDeploy, and Azure: So Happy Together

Sean is going where no presenter should ever go -- a live demo! Continuous integration and automated delivery are considered best practices, but how does it actually happen? During this talk, Sean will create -- from scratch -- a CI/CD pipeline for a real project using TeamCity, OctopusDeploy, and the Azure cloud. Along the way, we'll discuss Chocolatey, deployment slots, nuget packages, and more. We'll also touch on Appveyor and some other Azure deployment methods, as well as the "why" of CI/CD.

(Fr)agile: How Agile Falls Apart, and What You can do to Hold it All Together

Working in an agile mindset -- especially when favoring specific approaches -- can go wrong in about 100 ways. In this talk, I describe some lessons as a technical lead and member of agile teams, holding it together with duct tape and a little help from my friends.

Stretching .NET: An Introduction to ElasticSearch

NEST is a fantastic client for the ElasticSearch DB, which has a number of performance advantages and great use cases for solving modern development problems. In this session, you’ll learn some background about ElasticSearch for .NET, and will work through a real-world use case for utilizing it in your applications.

An Introduction to Graph Databases in .NET with Neo4j

Modern development shops are fast discovering that tables & rows aren't the only way to store data. In this talk, I introduce .NET developers to the advantages of graph databases using Neo4j. You'll learn how graph databases differ from traditional SQL DBs, when it makes sense to use a graph database, and what the advantages are. We'll also work through an example project to get a feel for some of the concepts, and sprinkle in a littler Docker goodness for some added fun.

How I Learned to Stop Worrying and Love Feedback Loops

In this talk, I discuss what feedback loops are, why they’re important, and the myriad ways that shortening feedback loops can improve your code, your team, and your career.

Casting a Wider .NET: Working Toward More OSS Maturity in the .NET Community

This talk discusses how to bring a model of open-source maturity to the .NET community in the hopes of getting others involved to realize our shared vision to make .NET a great space for open-source.

A Better Impact: Using Impact Mapping to Explore Representation at Tech Conferences:

Impact mapping is a powerful technique to orient your team toward achieving outcomes instead of writing features. In this talk, Sean will introduce impact mapping and explain its uses and benefits. To explore this concept, he will use impact mapping to demonstrate a path toward something he is passionate about – more diverse representation at conferences, both for attendees and speakers.
