Palash Sarkar has designed interfaces for fintech platforms, crypto exchanges, esports products, and consumer apps, and no matter how different the brief, the same handful of principles keep showing up in the decisions that actually make a design work. None of these are secret — they're taught in every design course — but knowing them and applying them consistently under deadline pressure are two very different skills. Here are the 10 Palash Sarkar comes back to on every project.
Principles That Create Clarity
- Visual hierarchy. The most important element on a screen should be the easiest to find, without a caption explaining why.
- Contrast. Text and interactive elements need enough contrast to be legible in bad lighting, not just on a calibrated design monitor.
- Alignment. Nothing undermines a design's credibility faster than elements that are almost, but not quite, aligned.
- Proximity. Related items should sit close together; unrelated items should have real space between them. Grouping does half the explaining for you.
Palash Sarkar treats these four as non-negotiable — they're usually the difference between a screen that reads instantly and one that needs a second look.
Principles That Build Trust
- Consistency. The same action should always look and behave the same way, everywhere it appears in the product.
- Feedback. Every action a user takes deserves a visible response — a state change, a confirmation, something.
- Forgiveness. Good design assumes people will make mistakes and makes those mistakes easy to undo.
These three matter more in fintech and crypto UI — categories Palash Sarkar has designed extensively — than almost anywhere else, because a user who doesn't trust the interface won't complete a transaction, no matter how good it looks.
Principles That Respect the User's Time
- Progressive disclosure. Show what's needed now; reveal complexity only when the user actually asks for it.
- Fitts's Law. Frequently used targets should be large and close at hand; rarely used ones can be smaller and further away.
- Accessibility. Designing for people with different abilities isn't an add-on step — it's part of getting the first eight principles right in the first place.
Key Takeaways
None of these 10 principles are individually impressive — what makes a design feel effortless is applying all of them together, consistently, on every screen, not just the hero screens in a portfolio deck. That consistency is what Palash Sarkar treats as the actual craft of UI/UX design.
