What I'm looking for

I’m looking for a company with amazing people, product market fit, and opportunities to have high impact.

I'm a Senior Software Engineer with a strong background in architecting scalable and fault-tolerant systems. At Bloomberg, I developed a real-time async event-driven system that improved client satisfaction by 20%. My experience spans multiple technologies, including Kotlin, Python, and Kafka, and I have a proven track record of leading teams and projects that enhance operational efficiency.

Previously, at Compass, I played a pivotal role in processing over 1 billion web activity events, which became the primary data source for AI/ML models. My contributions were instrumental in the company's successful IPO in 2021. I thrive in dynamic environments and am passionate about leveraging technology to solve complex problems and drive innovation.
