Darshana

3+ YRS - Software Engineer

Software Engineer crafting seamless digital experiences from backend architecture to pixel-perfect interfaces.

Engineering fit, not just features

I don't start with a familiar stack, I start with the problem, studying the domain, the edge cases, and what's already been tried until I understand what's actually failing and why.

From there I bring in whatever genuinely fits, proven patterns, new frameworks, AI-assisted workflows, filtered through critical thinking instead of trend-chasing. The tools serve the solution, not the other way around.
