About

I’m a Backend Software Development Engineer (SDE-2) with ~4 years of experience building and scaling high-throughput, fault-tolerant distributed systems in FinTech and large-scale SaaS platforms. At Wio Bank, I have worked on international payments domain, designing Kafka-based event-driven systems with idempotency, retries, and async orchestration, reducing end-to-end transaction processing time by up to 20x (mins → seconds). Previously at CommerceIQ, I scaled backend automation platforms handling 700,000+ actions/day and 10,000+ actions/hour by building resilient microservices and optimizing throughput under heavy rate limits and external dependencies. I enjoy working on: • Distributed systems & backend architecture • High availability, reliability, and scalability • Event-driven systems (Kafka, async workflows) • Production ownership, observability, and on-call Tech stack: Java, Go, Python | Kafka, Redis, SQL/NoSQL | AWS, Kubernetes | CI/CD, monitoring Currently open to SDE-2 / Backend roles.

Designed and implemented a fault-tolerant cross-border payments platform using a Kafka-based, step-driven event architecture, enabling idempotent processing, async orchestration, and reliable retries, and reduced end-to-end transaction processing latency by 20x.
Built a distributed message management framework with idempotent Kafka consumers for SWIFT message processing (MT103, MT202, MT199, MT950), enabling safe replays, horizontal scalability, and handling 450,000+ financial messages per day.
Developed real-time observability and audit dashboards using Grafana and Metabase, improving system visibility and traceability, and reduced incident recovery time by 60%.
Collaborated with cross-functional stakeholders to improve back-office tooling, validation layers, and timeout handling across payment workflows, resulting in 30% fewer support tickets, 35% reduction in RFIs, and 20% faster issue resolution.
