I build high-throughput Java microservices for aviation, streaming, and enterprise platforms.
What I'm looking for
I build Java backend systems for AMC Global Media’s OTT platform, delivering services for content discovery, subscriptions, identity, personalization, VOD, licensing, and offline viewing.
Previously, I built aeroCONNECT from scratch for Air Arabia: a cloud-based, high-throughput aviation messaging platform integrating airline, third-party, and government systems through Kafka, JMS, IBM MQ, Couchbase, gRPC, and AWS. I also led stabilization and feature delivery for airline pricing and seat-inventory systems.
Across Toptal consulting engagements, I’ve developed inventory-management backends, high-volume data-ingestion pipelines, MongoDB aggregation queries, OCR integrations, audit capabilities, and secure licensing mechanisms.
I bring 10+ years of production Java experience, combining hands-on architecture and delivery with production support, code reviews, recruitment, mentoring, and technical training across distributed international teams.
