What I'm looking for

I seek senior engineering roles building cloud-native microservices and data pipelines in fintech or e-commerce, with opportunities to lead teams, mentor engineers, and deliver measurable product and performance improvements.

I am a Senior Software Engineer with 15+ years designing and building scalable web applications and distributed systems for high-traffic fintech and e-commerce platforms. I specialize in microservices architecture, cloud-native solutions (AWS/GCP), and performance optimization, and I led a data pipeline optimization that reduced run-time by 80% (5 hrs to 1 hr) for a 5GB daily ingest.

I have deep backend expertise in Java, Python, and Node.js, experience with Kafka and real-time processing, and a strong track record in product collaboration, A/B testing, and mentoring engineering teams. I deliver measurable improvements—such as a 10% lift in AOV through personalization and a 30% reduction in ride wait times—while building resilient, observable systems.
