Devops

As an experienced coder who’s been playing with UNIX systems 20+ years, automating operations 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.
• Much 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, post-mortems after incidents.
• Writing and using run-books to manage changes gracefully, including back-out plans if there are unexpected setbacks.
• Preventing alert fatigue by working with developers/devops folks to reduce false-positives.

• 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 (both Ruby on Rails, Sinatra, and standalone applications)
• C#, Java (Spring/Hibernate)
• Javascript
