What I'm looking for

I seek a dynamic role where I can leverage my skills in AI and full-stack development, contributing to innovative projects while fostering a collaborative and growth-oriented company culture.

As a self-taught Full-Stack Engineer with over two years of experience, I specialize in building scalable web applications and developer tooling. My journey has led me to develop AI infrastructure, particularly focusing on VS Code extension development and Python-based AI agent orchestration using LangChain and LangGraph. I am passionate about creating intelligent developer tools and financial platforms that operate at scale.

In my current role at AmoYou AI, I designed an AI-powered code assistant that integrates seamlessly with IDEs, enhancing developer productivity through real-time autocomplete and error correction. My previous experience as a Software Developer Intern at Khatabook allowed me to build robust features for a cross-platform app, significantly increasing user engagement. I thrive in environments that challenge my skills and allow me to contribute to innovative projects.
