Hello, World!

I'm Mukesh Joshi

Design Architect & Software Developer

I am a Design Architect driven by a simple conviction: "A better solution exists." My journey began as a Java Software Developer in India, took me to Barcelona in 2017, and brought me to Stockholm in 2023. I focus on supporting architectural alignment, contributing to cross-cutting engineering topics, and working with open telecom & security standards. When I'm not collaborating on architecture topics, you'll find me hiking, exploring new technologies, and experimenting in my self-hosted sandbox environment—hence this website.

"Hutta" — my daughter's first word for babies. A name born of pure curiosity.

About Me

A brief look into my professional principles and hobbies

Design Architect

I support architectural topics, help align distributed engineering teams on shared design models, and contribute to cross-cutting concerns across scalable platforms. I strongly believe that a better solution always exists.

Enterprise Java Developer

My core engineering foundation is Java. I contribute to building and evolving secure, reliable services using the Spring ecosystem and relational databases, supporting transitions toward modular, cloud-ready architectures.

Tech & Hiking Enthusiast

Outside of system design, I enjoy discovering new tech, hiking across Europe, and visiting family in India. I use my personal sandbox to experiment with emerging frameworks and upgrade my technical skillset.
