I'm Pierre FILSTROFF. A senior software engineer based in Strasbourg, France.

Software engineer with over 15 years of experience, I specialize in Ruby on Rails and Hotwire, with deep expertise in Android and iOS mobile development. My versatility allows me to master both backend development and the creation of native mobile applications.

Currently a senior software engineer at Heloa, I work as an individual contributor on the Malo product, focusing on Ruby on Rails. I tackle diverse technical challenges — from implementing pub/sub in-app purchase notifications and integrating health check-ups, to setting up self-hosted monitoring with Grafana and Prometheus, building Elasticsearch-based recommendation systems, and configuring Kamal deployments. Previously as Senior Lead Developer at Heloa, I served as the technical referent of the Malo team alongside the CTO, responsible for product security, API and mobile releases, and development of Android/iOS applications using turbo-android and turbo-ios.

Rigorous and methodical, I invest myself in each project with a quality-oriented approach and continuous integration. My global vision of the software development cycle, from design to production, enables me to provide complete, long-term solutions to the most complex technical challenges.

Beyond backend and mobile, my interests extend to Docker, Kubernetes, DevOps, and self-hosting infrastructure with Proxmox. Father of three, I dedicate myself to my family and my work which is also my passion. I love to learn and share my knowledge with others — pushing my limits is a daily challenge.
