Who I Am

About Me

I'm a software engineer from Bhaktapur, Nepal, currently working as an AI Developer at Bent Ray Technologies. I hold a Bachelor of Engineering in Computer Engineering from Khwopa Engineering College.

My journey started in PHP and full-stack web development, and over six years I've grown into architecting SaaS products, microservices, and real-time communication systems. Since 2024 I've focused on AI โ€” building chatbots and SMS bots with self-hosted LLMs, OpenAI, and Gemini using RAG pipelines.

Beyond code, I've led teams as a Project Lead and certified Scrum Master (PSM I), mentoring junior developers and shipping products on time.
