I build reliable backend integrations and distributed fintech platforms.
What I'm looking for
I'm delivering a bank-platform implementation at Vyntra Global, deploying fraud and transaction-monitoring analytics across client server clusters. I build Python and Bash automation, troubleshoot Kafka, Mesos, Helix, ZooKeeper, and Elasticsearch, and harden RHEL systems with Ansible, mTLS, and OAuth 2.0/OpenID Connect.
Previously at Davis & Shirtliff, I built multi-country tax and e-invoicing integrations connecting Microsoft Dynamics 365 Business Central to revenue-authority systems in Zambia, Tanzania, and the DRC. I also built real-time Kafka pipelines handling 10,000+ IoT messages daily, improved API transaction processing by 40%, and developed automation, reporting, and internal platforms used across the business.
