Ahmad Mukhtar

Senior backend engineer with 5+ years building large-scale, event-driven distributed systems in Java (17/21), Kotlin, and Spring Boot. I've designed and operated service-oriented backends for a multi-tenant, high-throughput card-issuing SaaS platform, using Kafka, SQL stores, and Redis to process transactions reliably at scale. My recent work centers on data-platform infrastructure, running Flink CDC ingestion from MySQL into StarRocks for low-latency analytical SQL. A few things I've shipped: a Delinquent Adjustment Service that cut manual reconciliation cases by 82%, a modernization of legacy Java/Struts modules to Spring Boot 3 that raised test coverage from 40% to 95%, and payment/reconciliation microservices owned end-to-end on AWS (ECS, S3, CloudWatch). I'm looking for a remote senior backend role focused on distributed systems, fintech/payments, or data infrastructure, ideally somewhere I can own services from greenfield design through production operation.
