What I do well
My background is in multi-role enterprise platforms, data-dense dashboards, and 0 to 1 products. I have shipped five-role clinical platforms managing 100,000 patients and redesigned feature-dense SaaS products without breaking live operations.
I think in systems, work across the full design process from research through handoff, and push back on the brief when the framing is wrong. Pretty screens are the easy part. The hard part is products that hold up in production.
I am not a strategist or a brand designer. I am a senior IC who works alongside PMs and engineers and produces interfaces that actually ship. Since 2025 I also build working software with AI coding tools: two Android apps, a design-tool prototype, and several production sites, including this one.
How I work
I ask why the brief exists before I open Figma.
Most design problems are framing problems wearing a costume. Before pixels, I ask whether the problem is framed correctly, what the second-order effects of the proposed solution are, and what success looks like.
I write more than I draw.
Every component, flow, or system I deliver comes with the reasoning attached. Engineers know why a dropdown beat a modal. The next designer can pick up where I left off without a long handover call.
I ship and stay through QA.
I work in production-adjacent fidelity from week one and treat handoff as the actual deliverable. I stay in the loop through implementation and QA so the product that ships matches the product that was designed.
I am honest about scope and trade-offs.
If something is going to take three weeks, I say so in week one. If a feature is going to make the product worse, I push back before I execute it. You are paying for senior judgment, not senior compliance.

What I bring to a product team
Dashboards that hold up under real data.
Most dashboard mockups quietly assume 8 rows and 4 columns. Mine assume 50,000 rows and someone on a critical Zoom call.
Regulated and high-stakes UX.
Fintech payment flows, healthcare workflows, KYC, clinical interfaces. HIPAA, PCI, FDA-adjacent. Calm, accountable design under constraints.
Design systems engineers actually use.
Token architecture, component APIs, documentation that survives the designer leaving.
Product problems into interface decisions.
This is the senior part. Anyone can move boxes around. The job is knowing which box, why, and what it costs you.
Working with non-designers.
PMs, engineers, clinicians, founders. Plain language, no jargon ego, decisions documented in Notion.
Tools: Figma, ClickUp, Slack, Notion, Loom, Framer, Webflow, Cursor, Claude Code
Outside the work
I teach UI/UX at UIMC, partly because explaining a thing is the fastest way to find out whether you understand it. I mentor designers across South Asia informally, mostly over coffee and overlong Loom videos.
