I am a Senior DevOps Engineer with a decade of experience building cloud-native platforms and production-grade financial systems, focused on transactional correctness and operational reliability.

I design and implement double-entry ledger services, payment provider integrations, and core lending workflows using Node.js with TypeScript, PostgreSQL, Kafka, and Kubernetes, prioritizing ACID integrity and idempotent processing.

I have driven migrations to EKS and AKS, automated infrastructure provisioning with Terraform and GitHub Actions, and introduced observability and SRE practices that materially reduced MTTD, MTTR, and rollback incidents.

I mentor teams on ledger design, secure payment handling, PCI-DSS patterns, testing strategies, and CI/CD best practices, consistently improving reconciliation accuracy and deployment velocity.
