What I'm looking for

I'm looking for remote backend and platform work in EU/EMEA time zones, building reliable data integrations and event-driven services with PHP, Symfony, DDD, Kubernetes, strong automated quality practices, observability, and collaborative code review.

At Productsup, I build the Connector Development Environment, a Kubernetes-based platform that internal teams and external developers use to build, run, and monitor data integrations. I work on Symfony 7 and PHP 8.3 services that orchestrate isolated connector runs, use S3-compatible storage, and publish Kafka events for other teams.

I helped evolve runtime orchestration from scheduler-based polling to Kubernetes API-driven events, reducing API load and worker footprint. I also work across connector runtimes, DuckDB/DuckLake migration, streaming endpoints, SDKs, reference connectors, public documentation, testing, GitOps, and production investigation.

Across Productsup, Oracle, eMAG, Orange, and Incognito Concept, I’ve built and improved PHP backends, integrations, microservices, and cloud infrastructure. I keep domain code free of infrastructure through DDD and CQRS, and treat automated testing, static analysis, observability, code review, and AI-assisted engineering tooling as part of delivering every feature.
