Klira
2017-01 - 2019-04
Klira is Sweden's third largest broker for consumer loans. During my tenure we grew the team from zero to 18 tech team
members. My responsibilities included from architecture to architecture to compliance.
Our first challenge was in replacing the PHP legacy backend with a new micro-service architecture with Kafka as the mes
sage broker, all hosted on Kubernetes. A key aspect of this replacing the legacy system was in utilizing Kafka as an event
-log so that writes could be replicated and written to both systems.
We also decided to replace the front-end systems with a "micro-service"-based front-end architecture where each group of front-end use-cases, gets its own front-end code-base. This way, if a single front-end system turned out to be poorly
written it could easily be replaced.
Metrics and monitoring turned out to be important for us and the next step, was to implement a modern and scalable mo
nitoring solution that could be used by in a DevOps fashion by the developer's. I worked on setting up a modern metrics
stack based-on Prometheus and the accompanying JMX agent.

Aevy
2015-02 - 2017-01
Aevy built a search engine for finding candidates for recruiting. To do this Aevy aggregates data from various sources on the web such as Github, StackOverflow and Facebook.
My first task at Aevy was replacing the Ember-based front-end with a new front-end based on React.JS. As part of this w
e went from a semi-interactive app to one that is fully interactive and felt like a single page web app.
The next challenge was Dockerizing the Ruby on Rails application and the other services so that we could start using Doc
ker both in development and in production. After dockerizing the applications the natural next step was to introduce Ansi
ble so as to replace manual operations for the infrastructure.
The next project was replacing the basic queuing/worker system based on Redis/Sidekiq with RabbitMQ which offers imp
roved reliability, which allowed us to switch to a more event rather than task driven architecture.
As we grew we wanted to index more data and the next step scaling up our Elasticsearch cluster from 3 to 15 nodes (eac h with 64gb). The cluster was operated using Ansible and deployed to bare-metal servers.
After adding even more load our Postgres Cluster started performing poorly and we had to design a solution for this. To s
cale up beyond a single database node, allowed by postgres, we decided to switch to Cassandra for certain types of data, and I setup a cluster for this.
My final big project at Aevy was setting up a large scale email validation system that used SMTP to milions of email-addr
esses. To achieve the speed we wanted we needed to use a large number of connections and threads; so many in fact th at even Java could not handle that kind of load. For this reason I used Elixir, a variant of Erlang having better syntax.
