Event-driven backends and distributed systems.

Munich, Germany

About

I build event-driven backends and distributed systems — the kind that have to keep moving when a downstream service stops answering. Most of that work is Python: FastAPI and Flask services, Kafka topics between them, PostgreSQL and MongoDB underneath, running on Kubernetes across AWS, GCP and Azure.

Over 5+ years I have done that for aircraft manufacturing at Joby Aviation, order routing and logistics at H&M, advertising workflows at Stylight, and BMW's autonomous driving platform at DXC.

On the side I run Dnsium and a handful of small DNS and networking tools, which is where I get to own the whole thing end to end — the Next.js frontend, the Go API, and the Terraform and Ansible that put them on a server.

Experience

  1. Software Engineer, Joby Aviation

    – Present

    Munich, Germany

    • Built backend services integrating internal factory systems with various tools used in aircraft manufacturing.

  2. Software Engineer, H&M Group

    –

    Stockholm, Sweden

    • Developed event-driven microservices for order routing and logistics across multiple distribution channels using FastAPI, Apache Kafka, PostgreSQL and MongoDB.
    • Built and maintained high-volume event-processing services deployed on Google Cloud Kubernetes infrastructure.
    • Designed fault-tolerant distributed systems with retry mechanisms, message ordering guarantees and resilient handling of partial failures using Kafka and Pydantic-based validation.
    • Improved observability and operational monitoring using Datadog and structured service instrumentation.

  3. Software Engineer, Stylight

    –

    Munich, Germany

    • Designed and developed backend APIs and microservices for advertising workflows and partner integrations using Flask, Falcon, SQLAlchemy and Alembic.
    • Built scalable AWS-based systems using ECS, Lambda, SQS and SNS to handle traffic spikes during campaigns and peak seasonal demand.
    • Automated Google Ads product feed generation and data-processing workflows using PostgreSQL, DynamoDB, Redshift and Google BigQuery, improving data quality and reducing manual workload.
    • Delivered performance data pipelines and monitoring solutions with Datadog to support ad optimisation and revenue tracking.

  4. Junior Software Engineer, DXC Technology

    –

    Sofia, Bulgaria

    • Developed monitoring and data-processing services supporting BMW's autonomous driving platform using Python, Flask, Apache Airflow and Kubernetes.
    • Designed and executed performance and reliability testing for distributed systems, leveraging NumPy and pandas for large-scale data analysis.
    • Enhanced observability through centralised logging and monitoring with Elasticsearch, Logstash, Kibana (ELK) and Grafana, improving issue detection and diagnosis.
