About

From the
front line
to the code

Hey, I'm Alex. I started in customer support at Ubiquo Labs — resolving 1,300+ incidents for banking and government clients with 98%+ satisfaction. That front-line experience gave me something most engineers don't have: an obsession with how things feel to the user.

Now I architect multi-threaded microservices processing millions of daily SMS transactions using Spring Boot, Kafka, and ActiveMQ. I've optimized database performance by 80%, built SDK suites that cut client onboarding from 2 weeks to 3 days, and created automation that eliminated 80% of support tickets. Currently pursuing my Master's in Information Security.
