Message

On Bitwyre’s crypto trading platform, I maintained Python and Rust microservices and developed the KYC verification system for customer onboarding. I also worked on event-driven data processing with Kafka and Red Panda.

At RK Industries, I developed Python and Django applications, RESTful APIs, and PostgreSQL solutions. I also worked on enterprise integrations and asynchronous processing with Jitterbit, Celery, and Redis.

Across projects with papamana.com and Karamel.id, I developed websites, dashboards, and APIs. My work has also included NLP systems, data integrations, and services deployed in Docker environments.
