At Alaris Labs, I enhanced an asynchronous messaging pipeline processing up to 25,000 SMS per second, using parallel processing and Apache Kafka.

I also expanded the payment platform to support Stripe, PayPal, Revolut, and TripleA. I built the TripleA integration and implemented a unified payment flow with webhooks, verification, and idempotent processing.

At BIFIT, I implemented backend updates for the iBank banking information system and improved PostgreSQL query performance and service stability.

At Digital Economy League, I progressed from QA Engineer to Java Backend Developer and Key Subsystem Developer. I led backend development for a team of four developers and one analyst, and worked on microservices, REST APIs, and distributed workflows.
