Building trust into systems and shipping products that move the physical world. I build in three places at once — identity & access security, an actual quick-commerce startup, and an ML routing research track heading for publication.
I engineer trust into systems and ship products that move the physical world.
I'm a final-year Computer Science engineer at BMS College of Engineering, Bangalore. My path started with a curiosity about how large systems trust each other and ended up crossing into how physical supply chains actually move.
I found the intersection accidentally. While researching ML-driven electric bus routing for a journal, I was also negotiating with cement suppliers to fulfill 60-minute deliveries for BuildMart. In parallel, I was thinking hard about who gets access to what, and when — the quiet problem that underlies every product that scales.
So my work today runs on three rails: applied security in identity & access engineering, building BuildMart into a real quick-commerce operator for construction materials, and pushing SPARC-EB toward publication. The through-line is the same: engineer trust into the system before scale forces the question.
Ship things that survive contact with the real world — supplier trucks, hostile networks, and regulators — not just the demo.
Case studies from a founder and a researcher — same person, same operating system.
How I think about trust, access, and systems at scale.
I work in identity & access security — the discipline of deciding who can do what, when, and under what conditions. It's less about tools and more about designing trust surfaces that don't collapse when the org grows 10x.
Authorization Models
RBAC, ABAC, ReBAC — choosing the right model per system, then making the policy actually observable and testable. Access decisions should be diff-able, not tribal knowledge.
Access Governance
Reviewing, certifying, and revoking access at scale. Turning access reviews from a compliance exercise into a signal of organizational risk.
Identity Lifecycle
Joiner-mover-leaver flows that are provably correct. Access follows the person and the role — not the ticket.
Emergency Access
Break-glass frameworks that grant privilege fast, log irrefutably, and revoke automatically. Trust the process because the process forces the paper trail.
