Special Circumstances Ltd
January 2017 - current
Freelancer
I founded Special Circumstances to be free to offer the best of the expertise I gathered so far in my career, anywhere, to any firm in the world.
Special Circumstances coaches and supports teams and firms on a wide variety of important tasks that constantly challenge the modern IT industry, like:
- choose right tools and Cloud providers
- how to migrate from/to the Cloud strategies
- Infrastructure as Code setup and refactoring
- extend system automation to free operators from toil
- gather visibility over KPIs through telemetry
- unit + integration + E2E test and code review workflows via Continuous Integration / Continuous Delivery pipelines
- Serverless architectures and dev environment (local and remote) setups
- SPA applications leveraging modern technologies like reactive/responsive web frameworks and JAMStack
- planning and execution of deliverable (build) deploys, dataset migrations, middleware major version upgrades, etc.
- Monolith vs. Micro-services strategy analysis
- (virtual) network layout design
- …and more
Keeping everything secure and usable by both end users and operators is our most dear core value.

Bonial International GmbH
Berlin (Germany)
July 2013 - December 2016
Senior System Engineer
Bonial, multinational business in the publishing field, was looking for someone willing to embrace the challenge of refactoring their relatively big Puppet codebase, all while expanding their operations. I was eager to get onboard and test my skills on a new scale (thousand of servers).
I happily joined the Operations team as team lead and put in charge of the overall infrastructure stability, robustness and maintainability, enforcing best operational practices.
In my years at Bonial I witnessed first hand the IT department and especially the Operations team exponential growth. We regularly faced interesting new challenges, some of them planned, like cloud providers migrations (from Rackspace to AWS), some of them unexpected and frantic, like embracing the new micro-services paradigm, which in itself put an incredible amount of new goals and responsibilities on my team.
As the new way took off more and more, we gradually abandoned self managed hosts (and Puppet with them) moving towards cloud services. Terraform was our tool of choice to help us manage at best our multi-account, multi-region AWS setup. We decided to implement internally our Terraform orchestrator to better integrate with our CI/CD pipeline, react to failures, and enforce good coding practices.
The technological stack:
- AWS / Rackspace cloud
- Debian GNU/Linux
- Ganeti virtualization
- Docker
- Terraform
- Puppet
- Icinga
- Apache web server
- Tomcat/JVM
- PostgreSQL
- Python automation with Fabric and Boto libraries
- Jenkins
- Gerrit
- Datadog
- OpenLDAP
- data confidentiality with LUKS

Senior System Engineer
Technical operations lead, in charge of the infrastructure (mostly AWS based) overall stability and scalability. Responsible for the constant improvement of transparency and visibility (via logging and monitoring), and maintainability of the platform (via config management/automation).
I took over all the things operations and gradually worked to introduce new tools and practices following the DevOps principles. Upgraded config management from internally developed Bash-based system to a Puppet-based one. Added visibility and telemetry with Zenoss Core and ELK stack (Elasticsearch, Logstash, Kibana).
The above effort enabled the infrastructure to sustain a fast grow that eventually brought us to the 1 million users target and above.
