Test Automation and Accounting Tool for Blockchain

Software Engineer Go Rust Kubernetes ...
Software Engineer
During my time at Parity I mainly worked on two projects, which I designed and implemented from scratch.

The first was automation for "burn-in testing" of in development versions of Polkadot. The system was written in Go with a simple React frontend, used a GitOps approach and GitLab CI to manage deployments and integrated with Matrix-based chat for notifications (https://github.com/haikoschol/burn-in-tests).


The second project was a custom indexer for Kusama and Polkadot plus a web application to access the indexed data. The indexer and backend API were written in Rust and the web frontend in React/TypeScript. Everything was deployed to Kubernetes and the indexer jobs were managed as CronJobs.


Apart from that I collaborated with the infrastructure engineering team to deploy and manage the infrastructure for above mentioned tools and improve Prometheus-based monitoring and alerting.

Machine Learning pipelines on Kubernetes

Software Engineer Python Kubernetes AWS
Software Engineer
 

The Pricing & Forecasting department delivers sales forecasts and pricing recommendations that are crucial to the business.

My responsibilities included development of Kubernetes operators for orchestrating machine learning pipelines in Python, based on an open source framework (https://github.com/zalando-incubator/kopf).

The team I worked with was going through a transition period, with many new joiners within a few weeks. I accelerated onboarding of the new members by giving talks about architecture and code deep dives, in-depth code reviews and pair programming sessions.

Software-Entwickler

Joining the IaaS Management team, I worked on a product that allows teams to describe and
maintain cloud infrastructure as declarative code. It is similar to Terraform, but more tailored to
common use cases and focused on enabling a collaborative, git-based workflow.

As part of the Open Source Team at HERE, I worked on automating the legal compliance workflows
(licenses, copyrights, patents, etc.) for releasing proprietary software to customers, as well as open
source projects.
My responsibilities included contributing to tooling used by the team, such as ScanCode
(github.com/nexB/scancode-toolkit) and OSS Review Toolkit (github.com/heremaps/oss-review-
toolkit) as well as helping teams inside the company understand and complete the process.

Managed WiFi Platform

Software-Entwickler Go AWS Docker ...
Software-Entwickler

Superscale builds a managed IoT/WiFi platform, leveraging consumer hardware running OpenWRT (with our additions written in Rust)

My focus was on the "cloud" side of the product, which consists of an external HTTP/JSON API, a few internal services and a messaging layer built on MQTT.

My main responsibility during this contract was extending the upload mechanism to allow appending data to existing datasets. Additionally I contributed to the design of an interactive upload process, that allows the user to adjust various parameters that were inferred/suggested by the software.
