What I'm looking for

I'm looking to build scalable backend infrastructure, payment workflows, and event-driven distributed systems where I can deepen my Golang, system design, and fintech engineering experience.

I'm building Golang-based payment infrastructure at Triple-A, integrating Fuse and Numeral for cross-border fiat payments, AED payouts, and EUR IBAN SEPA and SEPA Instant transactions.

I've migrated Fireblocks webhook processing from V1 to V2 through a feature-flagged rollout, and built Dedicated Wallet infrastructure that moved 33K+ merchants to unified wallet workflows for top-ups and invoicing.

At Castler, I independently built a CDC pipeline with Spring Boot, Debezium, Kafka, MySQL, and Redis, including initial migration of 300K+ records and near-real-time synchronization workflows.

I also build Golang microservices, API gateways, gRPC and GraphQL services, authentication flows, and scalable backend architectures.
