Where it began
My story
Arjan Walia
Founder of OpenHearth · Pianist & builder
Music, technology, and accessibility. Rooted in Seva.













Growing up, beyond years of rigorous training in piano, my grandmother’s (Dadi’s) philosophy of “Seva” (selfless service) has shaped my identity. A lifelong teacher, she tutors under-privileged children and pays for their tuition.
As an avid pianist, I’ve always valued my access to self-expression. However, seeing others struggle with accessibility limitations made me question what happens when people cannot pursue what they love. Dadi’s philosophy of “success is measured by what you give, not what you accumulate” became central to my design choices for vulnerable populations facing barriers to accessibility, and it is always an inspiration for me to continue building for accessibility.
In middle school, I began exploring technology to answer this question. I learned that accessibility barriers stem from cost, physical ability, or mental health. My journey started when I coded a tennis biomechanics analyzer using Node.js and React to make private coaching affordable. But I soon realized cost isn’t the only hurdle people face, so I built solutions to manage mental health wellness and assist physically disabled pianists, using Python, Supabase, and Pandas.
For a deeper understanding, I advanced research in audio processing during UC San Diego’s selective COSMOS program and through IEEE publications. These experiences allowed me to address more complex challenges. I engineered a sensory-safe online stage with AI monitors for musicians, and developed an LLM-security framework for AI agents to prevent malicious activity, which also won a hackathon. Three internships have equipped me with cybersecurity and architecture expertise to build modern and safe solutions.
Putting Seva into practice continues through my service as a music therapy volunteer for people with Down Syndrome and a teaching volunteer for neurodivergent children.
I aspire to solve the same barrier Dadi is solving with books: access.
