What I'm looking for

I'm looking to own backend architecture and delivery for payment, authentication, workflow, or distributed systems, solving complex integration and reliability challenges.

I'm building and owning banking, payments, authentication, and e-commerce systems at Zethic, from architecture and API contracts through database design and release planning.

I rescued a stalled news portal engagement shortly before delivery by restructuring the technical approach and leading frontend and API recovery to a successful demo. I also serve as an escalation point for cross-system banking and payment integrations, resolving issues across frontend, QA, and infrastructure.

Previously at myautoIQ, I owned workflow systems from design through production monitoring and automated synchronization across four automotive CRM platforms. I improved high-volume MongoDB processing by redesigning queries, indexes, and scheduled-job execution paths.

Across projects including PINpoint, Leopay, and global commerce integrations, I've built configurable approval workflows, merchant payment platforms, identity services, asynchronous webhook engines, and idempotent synchronization pipelines. I work across Node.js, NestJS, Go/Gin, PostgreSQL, Redis, Docker, AWS, and automated testing.
