What I'm looking for

I'm looking to build scalable backend, ERP, payments, and compliance products where I can lead engineering teams and deliver high-performance user experiences.

I've led engineering for Westmetro's live FIRS/NRS e-invoicing compliance platform and its ERP integration surface, using Go, Frappe/ERPNext, PostgreSQL, RabbitMQ, and DigitalOcean Kubernetes.

At ParallelScore, I delivered scalable backend systems across healthcare, hospitality, and sports technology. I engineered ERPNext integrations with FHIR HL7 specifications, expanded a telemedicine platform with video conferencing, and built NestJS APIs for analyzing large soccer video datasets.

At OyaSync, I head the software engineering team and built three accounting products that help small businesses keep their books in check. I white-labeled ERPNext for fashion and hospitality businesses and extended its APIs for mobile and web applications.

I've also built payments infrastructure for CentryOS, including merchant commerce integrations, dispute handling, and API edge security. Across my work, I use Node.js, TypeScript, Python, Go, PostgreSQL, Kafka, RabbitMQ, and Kubernetes to deliver maintainable, high-performance products.
