Junior CRO Analyst (App Specialist)

LeoVegas (LeoVegas Group)

As a CRO Analyst at LeoVegas, I specialize in experimentation and A/B testing for our mobile apps, driving continuous optimization and data-driven decision-making. After six months in the analysis sub-team—where I led our Quarterly Business Review, monitored and reported key conversion metrics, and managed stakeholder data requests—I have transitioned to the CRO experimentation team, taking sole responsibility for testing on our apps. My role involves running A/B and A/A tests to optimize the app experience, defining and monitoring app-specific KPIs, reporting insights daily to the company, tracking and managing experimentation tickets in Jira, leading ceremonies with stakeholders to align on testing strategies, utilizing tools such as LaunchDarkly, Google Analytics, Contentsquare, Looker Studio, BigQuery, and GitHub to inform and execute testing strategies. With a background in bioinformatics and system development (Python, Bash, JavaScript, Firebase, GitHub), I bridge experimentation with technical implementation, collaborating closely with Analytics Engineering and Data Science to ensure robust tracking and meaningful insights.Passionate about data-driven growth and optimization, I thrive on transforming insights into impactful business outcomes.

2018 - 2024
Bioinformatician/System Developer

National Genomics Infrastructure (SciLifeLab, KI)

I delivered sequencing data to users from their sequencing projects and was method responsible for the data deliveries. I delivered mostly raw data (FastQ- or bcl-files), but also the BP analysis data of nf-core/RNASeq and nf-core/ MethylSeq, all of which I had run the analyses and performed quality checks prior to delivery, mainly from examining the correponding MultiQC report. I used BaseSpace Clarity LIMS to document my work and communicated with the users through ZenDesk. In addition, I also helped develop pipelines, external and internal web pages and interfaces using Python, JavaScript, PHP, HTML, and CSS using GitHub. I mostly worked with the internal website Genomics Status. I was responsible for the external website NGI Sweden and the pages on the SciLifeLab website. I did quite a bit of testing of the pipelines when these had been updated prior to production deployment and also wrote verifications and validations connected to those.

2017 - 2018
Laboratory Technician

Karolinska Institute (MTC), Centre for Translational Microbiome Research (CTMR)

I extracted microbe DNA from various samples from the research projects in Professor Lars Engstrand's research group using Tecan FreedomEVO. This was the first step in sequencing the DNA of the samples, which was carried out by my colleagues.

2015 - 2016
Laboratory Engineer

Octapharma Sweden, QC Support, Sample Reception

I received samples of pharmaceutical drugs in various phases of their production, imported these in SQL LIMS, and passed these on to the lab. I also handled the purchasing of supplies and equipment for the biochemistry lab, using SAP. In addition, I also delivered and received samples from other sites in Sweden as well as abroad.

2014 - 2015
Laboratory Engineer

Karolinska University Hospital in Solna, Department of Clinical Virology, Serology

I analysed blood plasma from patient samples for the detection of antibodies against various infections using ELISA, both automatically with the Tecan Freedom EVO robot and with manual analysis.
