About

I am a Software Engineer who loves building systems that are fast, reliable, and built to scale. Over the years, I’ve worked across different parts of the tech world, but I’ve developed a strong foundation in financial systems from payments to trading pipelines to real-time data flows. I enjoy the mix of precision, performance, and problem-solving that finance demands. I work mostly with Golang, Python, distributed systems, and cloud-native architectures, and I’m passionate about designing systems that stay resilient under load. I also explore areas like blockchain, HFT concepts, and low-latency architectures because I enjoy how finance pushes engineering boundaries. Recently joined Advisor360° as part of the AI Engineering team, where I’m working on intelligent systems that make life easier for financial advisors and improve how clients are served. I’m always excited about challenges that involve scale, real-time data, or deep technical thinking, and I love connecting with people who share the same passion for building impactful systems.
