@andrsbulla
I build distributed platforms, data systems, and reliable cloud architectures that improve performance at scale.
FranceWhat I'm looking for
I've designed platform and data architectures at Aircall and PriceHubble, from event delivery and storage systems adopted by 10+ engineering teams to distributed property-data pipelines spanning 30+ advertisement sites.
At Aircall, I designed a monolith-to-serverless telephony migration that cut incoming-call setup latency from about 2.0 seconds to 0.2 seconds. I also designed and maintained Airflow analytics pipelines processing around 3 million calls a day.
At PriceHubble, I reduced GCP costs by about 60% while improving operational visibility through Grafana, Sentry, and incident practices. Most recently, I've built an end-to-end AI-agent product in TypeScript, C#, React, Node.js, and Docker.
