• Building a web-based commission management tool consolidating 30+ Excel sheets into a centralized platform for 20+ partners. 

• Leading multiple SAP integration projects: Aconso HR system integration into SAP, SAP Business One to Azure data warehouse migration, and consulting on R3 to S/4HANA migration. 
• Successfully delivered PoC and contracted for full-scale rollout. 

• After a successful buyout of (name on request), at SBS we focused entirely on a new stack
• The new company only focusses on energy and heating management, which is only a small subset of the functionality that the noah platform tried to provide 
• There were also new features specific for the niche customers we encountered in addition to the existing customer base which was migrated
• Technically we moved from Azure to AWS, split our repositories between GitHub and Gitlab, moved from Jira to Linear, switched from MongoDB to InfluxDB and deprecated the monolithic infrastructure
• All our services are now deployed cloud natively, we worked with FastAPI for multiple micro APIs, which were layered and used to improve reusability
• At (name on request) we had a separate frontend team, but in SBS we started out as a shared team, so I also took on frontend responsibilities
• We are working with Vue 3 and the composition API using TypeScript
• We also switched to external authentication provider Auth0 (by Okta) and kept Stripe as a payment provider
• Even though we operate at much lower capacity (currently only one additional developer), we managed to automate most of the deployment tasks and are able to focus entirely on the development of new features

• For a private customer we built a tool for an uptime monitoring solution
• Users were able to monitor server uptimes and pings using different hubs for a low ping check on their web servers
• Furthermore we used n8n and the n8n API to integrate with different notification providers like Telegram Bot, Email or a custom web hook for the user
• The login was provided by Auth0 and payments were collected via the stripe API

• Delivered M365 rollout support for enterprise client Solvay, including training video production, user awareness sessions, and on-site change management to facilitate Google Workspace to Microsoft 365 migration. 

• Developed industrial data logger application in C# to consolidate and visualize serial device output for production monitoring. 

• Led technical development and team of 8 developers building IoT platform for building management and sensor data analysis. 
• Architected transition from Django monolith to FastAPI microservices across 3 products (web and mobile). 
• Managed DevOps, backend development, and cross-functional team leadership through ~2.1M? funding round. 

• As the resources of the small team were scarce, a lot of the IT infrastructure was being automated as it was deployed
• We worked with Ansible for some services, which were deployed on premise, i.e. n8n, traefik and Sentry
• Most of the load however was carried by services in the Azure cloud environment, where we utilized Azure functions, Azure web apps and databases
• Furthermore we worked with MongoDB to host the data for the IoT devices
• For the micro services we built custom GitHub workflows which would build Docker containers and deploy them in Azure or on premise
• For (name on request) I also built custom financial models in Microsoft Excel and maintained the Jira and GitHub instances, as well as taking care of deployment and testing pipelines

• For a private customer I built the backend for a document chat application
• Users of the application are able to upload a document and - using a selfhosted LLM - interact with the document
• The solution is targeted at German/European business clients, which is why beyond the LLM the vector storage is also self hosted
• My responsibility in the team was to implement the backend with FastAPI, write unit tests for the backend and deploy the solution on a custom Linux machine

• I co-developed a Wordpress website for fivehead, according to a provided design
• My responsibility were the technical details of the site, like hosting the site on a Unix machine, automating updates and backups and implementing the design in Elementor

• At Postbank we continued the project started at Deutsche Bank and supported the Postbank developers with the migration
• There were different smaller challenges that we didn?t encounter on the DB site, but overall we benefitted a lot of our established processes and workshops

• Supported enterprise M365 migration at Deutsche Bank and Postbank, coordinating with developers and application owners to migrate applications to 64-bit Office 365 platform.

• At Deutsche Bank I was part of the migration team for the Office 365 project
• My responsibilities were the technical consulting and coordination of tests of custom legacy applications
• Most of the applications were written in VBA or used an Office connection, so the transition from 32 bit based Office to 64 bit was a technical challenge for many
• Thus we supported the worldwide rollout and helped migrating over 5000 tools

Built automation tool for patent review and translation workflows using Django full-stack development. 

• In this natural language process project we built a tool, automating some parts of the patent reviewing process for a patent attorney
• We worked with the natural language toolkit library and Django as web framework
• We used frontend and backend capabilities of Django and TailwindCSS as a components framework

Bachelor thesis: on request (NetworkX, matplotlib).

• As a research assistant at Fraunhofer Institut für Werkzeugmaschinen und Umformtechnik I wrote a tool for converting ontologies into bayesian networks as a part of my Bachelors thesis
• The tool was written with NetworkX, matplotlib and different ontology specific tools

• For a private customer I lead the team to develop a full stack web application, which was also available offline
• The customer needed a Power-Point style presentation tool with a lot of custom gimmicks like special animations, a presenter panel with custom sounds or a live chat when used online
• We used Django as the back- and frontend and exported a Node based Electron app for offline use

• For a private customer I developed a full stack application in Django for hosting a small art store website, where the owners can upload pictures of their artwork to show online
