About Me
I'm a backend engineer with 4+ years of experience building production systems that handle millions of requests and terabytes of data. My journey started with building RESTful APIs, and evolved into architecting cloud-native solutions on AWS.
What drives me is the intersection of performance, reliability, and security. I believe the best systems are both powerful and maintainable—elegant solutions that solve real problems without unnecessary complexity.
Over the years, I've developed a strong focus on security-aware engineering. From implementing encryption and access controls to threat modeling and incident response, I approach every system with a "secure by default" mindset.
Currently exploring opportunities where I can contribute to building secure, scalable backend infrastructure—especially roles open to visa sponsorship.
