What I'm looking for

I seek roles building scalable web or ML systems with strong engineering practices, measurable impact, and opportunities to own end-to-end features in collaborative teams.

I am a full-stack software engineer and computer science student with strong foundations in web development, machine learning, and systems engineering. I build end-to-end products—from marketplaces with escrowed transactions to high-performance e-commerce features—while focusing on performance, reliability, and user safety.

My projects include ML explainability libraries, secure PDF redaction tooling, and a high-performance C++ plagiarism detector; professionally I shipped production systems that achieved sub-200ms page loads, 99.9% uptime, and thousands of active users. I prioritize clean engineering, measurable impact, and practical explainability in ML.
