About
More than a resume
Builder at heart — clean architecture, measurable impact, continuous learning.

I'm Brahmaiah — a Senior Software Engineer at ŽEJN Group in Ljubljana, Slovenia, holding an EU Blue Card. My decade-long career spans fintech credit card platforms processing 8M+ customer records, event-driven document pipelines, and cloud-native systems across 50+ microservices.

What drives me isn't just shipping code — it's designing systems that handle real-world chaos gracefully. I think in Kafka topics, circuit breakers, and SLA budgets.

Outside engineering, I'm building a Telugu-language YouTube channel for children's stories, exploring Europe, and constantly reading about distributed systems.
