I’m a Full-Stack Software Engineer with a strong focus on building fast, clean, and scalable digital experiences. I work primarily with TypeScript and Python, crafting intuitive frontend UIs and reliable backend systems that solve real-world problems.My background in competitive programming and hackathons shaped my ability to think critically and engineer efficient solutions under pressure. Today, that translates into writing clean architecture, thoughtful abstractions, and maintainable code across the stack. I’m currently expanding my expertise in Python backend development and exploring how AI-powered features can enhance modern applications—leveraging APIs, LLM workflows, and automation to build smarter tools. I believe in learning continuously, staying curious, and evolving with technology—one project at a time.
