Element Insurance AG - FinLeap, Berlin

Tätigkeitszeitraum

3/2017 – 2/2018

Tätigkeitsbeschreibung

Element is a German fintech startup part of the FinLeap ventures. We aim at revolutionising the world of insurance by digitalising the traditional products and conventional processes which are set in the industry. In the digital age traditional insurance products can unbundled and sold flexibly, tailoring them to the users' needs. Technology can be used to easily interact with the users, manage the selling and claim processes and connect to the partners and the brokers.

I am the only DevOps Engineer part of the scrum development team. I work closely to the Full-Stack developers to architect, build and automate the infrastructure, hosting the Java-based microservices, manage the release process and deploying the support tools to analyse, monitor and provide connectivity to the internal platform. In addition to that, I also execute more reactive tasks, such as solving bugs and fixing security threats affecting the platform.

The infrastructure is completely integrated with the AWS ecosystem and makes use of a number of products, such as EC2, S3, Lambda, ElasticBeanstalk, CloudWatch, DynamoDB, SQS/SNS, Elasticsearch/Kibana, etc.
Hashicorp Terraform is widely used to automate the deployment of the infrastructure, whereas immutable images are created using a mixture of Packer, Ansible, Docker and Molecule.

Continuous deployment is achieved using Jenkins 2.0 pipelines.
Internal scripts and support tools are written in Python, Ruby and Go.

I have also touched frontend and backend development (Java, React.js, CSS, HTML), helping the team in the resolution of application related bugs, performance issues or introducing new features.

After the strong growth of the company and the team split, I have taken the interim Lead role, shaping the team strategy, spreading the knowledge across the members and steering the meetings.

Über mich

I am a technologist, a generalising specialist with a passion for cross-functional development and system operations, in constant search of new material to learn and new challenges to overcome.

I am a passionate, energetic, committed, reliable individual. I believe employment is an opportunity to put my skills into practice, a chance to learn something new, a challenge to go beyond my limits.

I am a fast learner, who can grasp a particular situation and develop a solution to it, based on academic and professional experience.

I am a natural problem solver, I am creative, curious and balanced. I am ready to take stress out of negative situations and turn it into a positive challenge.

I have business acumen to understand particular needs and constraints and determine the product value in an organisation. I can identify appropriate technologies and methodologies. I can play a key role in any phase of the IT service lifecycle.

I recognise the value and take full advantage of team work. I believe that effective human interaction in a happy, stimulating and collaborative working environment is entirely reflected in the final product.

I can gather data from the environments in order to measure the current capabilities, drafting proposals to tune or upgrade in order to reach the desired overall performance and responsiveness and guarantee service quality.

I don't see the value of performing repetitive manual tasks. My mission is to offload work to machines, automating where possible.
