DevOps

As an experienced coder who’s been playing with UNIX systems for over 20 years, automating operational tasks comes naturally to me. However, there is more to DevOps/infrastructure than just automation. Especially for smaller organizations, where the overhead of fully-automated infrastructure is not always cost-effective.

I can help you:

• Professionalize your operations to keep your infrastructure fast, reliable and secure
• Find the root cause of that recurring bug bringing your systems down
• Prepare the documentation and code to quickly rebuild your infrastructure from scratch, in case of emergency
• Make incidents rare enough that your team takes them seriously every time

• Schedule a call
• Email me

On the technical side, I have:

• Centralized configuration and laid out the groundwork for automating infrastructure whenever appropriate
• Set up profiling instrumentation to determine the bottlenecks in complex microservice environments
• Performance-tuned configurations from Postgres to Varnish to JVM and more
• Built docker-based infrastructure to run network vulnerability scanners at scale
• And more

But I’m also familiar with the interpersonal side, such as:

• Making DevOps part of the team rather than the stereotypical techies in the basement
• Setting up and managing processes for capacity planning, performance monitoring, disaster recovery tests, authorization, and post-mortems after incidents
• Writing and using runbooks to manage changes gracefully, including back-out plans if there are unexpected setbacks
• Collaborating with developers/DevOps folks to reduce false-positives and prevent alert fatigue

• Schedule a call
• Email me

Some technologies I’ve worked with:

• PostgreSQL, Elasticsearch, MongoDB, MySQL, Redis, Solr/Lucene
• Graphite, Kibana, Grafana, Logstash, Icinga, Jenkins
• Varnish, HAProxy, Pound, Nginx, Apache, Passenger
• Ansible, Vagrant, Docker, DCOS, Kubernetes
• SSH, OpenVPN, TCP/IP
• tcpdump, strace, lsof, and friends
• Linux (Debian, Ubuntu), FreeBSD
• AWS (EC2, ELB/ALB, S3, CloudFront, Lambda, Batch, VPC, etc)
• Ruby (including Ruby on Rails, Sinatra, and standalone applications)
• C#, Java (Spring/Hibernate)
• JavaScript
