Career

Tech Lead

Since Nov 2020

Worten

Tech leading a team of 14. Designed and implemented solutions for order orchestration and shopping cart rules. Streamlined team's development process while deploying to production multiple times per week. Worten is part of Sonae group, which had 8.4 Billion € turnover in 2023. (more) (less)
Created a system processing 100's of thousands of order updates per day using mostly Kafka and PostgreSQL. Steered the team with continuous deployment methodology averaging over 2 releases per day (including hot-fixes) over the last two years.

Founder and Developer

Nov 2017 to Oct 2020

METRIC4

Developer of backend services and sensor firmware. Worked as a consultant since January 2020, the clients were based in Switzerland. (more) (less)
Developed a threads and messages middleware (in Rust) to run on low end hardware with intermittent connectivity. Wrote drivers for several peripherals, tools for logging and monitoring, self updated, still running today. Wrote services in Go for data ingestion, monitoring, user notifications, realtime feeds, KPI batch processes and metadata APIs. Contributed to a Rust microservices framework used to deploy services in a Kubernetes cluster. Communicated among services using gRPC and controlled ingress using Istio. Used a custom DSL to generate database schema and GraphQL queries / mutations. Provisioned everything using terraform. Invested heavily in CI/CD and fostered code reviews. Having never done it before, developed a frontend client facing application in Typescript using React. The apps ranged from IoT, banking, to warehouse management solutions.

Senior Developer and Product Manager
