01. About

Who I Am

I'm a Software Engineer with 5+ years of experience building scalable enterprise applications, cloud-native services, and modern web platforms. My expertise spans backend architecture, distributed systems, and full-stack product development.

Beyond professional work, I'm passionate about building products from scratch — taking ideas from concept to production. I've shipped a password management platform, a plug-and-play feedback SDK published to npm, and AI-powered automation services that leverage LLMs.

I believe great software combines technical excellence, simplicity, and user-centric thinking. My long-term goal is to build impactful software products and push the boundaries of what technology can achieve.
