About Sina

Design that feels intuitive. Code that quietly performs.

Sina works at the intersection of UI, UX, and web development. He translates business goals into interfaces that are simple to use and straightforward to ship. Every project starts with understanding users and ends with a maintainable build your team can grow on.

Bridges product, design, and engineering — so fewer things get “lost in translation” between Figma and code.
Obsessed with clarity: clear layouts, clear hierarchy, and clear handoff documentation for your team.
Focused on performance and accessibility so your experience loads fast and works for more people.

From cluttered interface to clear, focused product.

Imagine a SaaS dashboard overloaded with menus, widgets, and charts. Sina restructures it into a small set of clear, task-based views so users find what they need in seconds, not minutes.

Mapped top tasks and removed screens that didn’t serve a real user goal.
Introduced a consistent component library so new features feel familiar by default.
Improved clarity of tables, charts, and filters to reduce support tickets and onboarding time.

How does a typical project start?
+
Usually with a short call and a simple brief. Sina clarifies goals, scope, constraints, and timelines, then suggests a structure that fits your budget and priorities.
Can Sina work with our existing dev or design team?

Can Sina help with small one-off pages?
+
Yes, especially when those pages are important — like a launch page, pricing page, or feature announcement.
