Building Products
That Simplify Complexity

I'm Serhii. I design enterprise SaaS products that help people make faster decisions. Over the last 6 years I've worked on fintech platforms, analytics tools and internal enterprise products — where clarity matters more than visual trends.

Great products don't start with interfaces. They start with understanding people.

Working on financial platforms and internal enterprise tools, I've learned that the hardest part isn't drawing a screen — it's understanding who uses it, why, and what's stopping that person from making a decision faster right now.

My process rests on a handful of simple questions I ask at the start of every project — from a financial dashboard to a mobile app.

How I Think

The framework every project starts with

These questions get asked at the start — and then again a few more times along the way, because the answers are rarely final.

01Who are we designing for?
02What are their goals, motivations, and constraints?
03What problem matters most right now?
04What can we remove?
05What did we learn from real users?
06How can we make it even better?

Design systems aren't built for Figma. They're built for teams.

Deeper Dive

Four cases, in depth

01 · Enterprise Financial Analytics Platform

Analytic Dashboard

Problem. Customers kept asking for the same thing: a single place to understand portfolio performance. Reports existed, data existed — an analytics experience didn't.

Insight. Working with product managers and the sales team, I mapped the questions customers asked most: what changed, what requires attention, how is performance evolving, what should I do next.

Solution. Information was organized around those questions, not internal product logic. Multiple concepts were explored, balancing density, hierarchy and readability.

Scaling. As visualizations multiplied, I proposed a reusable Plotly component library — teams could build dashboards faster while keeping a shared style.

→ Became one of the platform's flagship products
→ Consistently positive feedback from customers and sales
→ A foundation for future analytics products
02 · Enterprise Financial Analytics Platform

Design System

Problem. The product was growing faster than visual consistency could be maintained across new analytics features.

Solution. A shared design language: variables, typography, components with variants — buttons, inputs, tables — plus documentation with precise spacing rules.

Principle. Design systems aren't built for Figma — they're built for teams. Reusable components cut duplicated work and made design–engineering collaboration much smoother.

→ A shared system of variables and components
→ Noticeably faster design–engineering collaboration
→ Documentation reduced ambiguity in review
03 · Enterprise Financial Analytics Platform

Issuance Monitor

Problem. Issuing financial products involves many teams and approvals. The challenge wasn't completing tasks — it was understanding where every process stood.

Pain. All the data lived in a single flat table: no filters, no views, no drill-down, no relationships between records.

Solution. Instead of one overwhelming table — several interconnected views: Deal View, Class View, K-Matrix View — with alerts, notes, exports and filters built into the workflow.

→ One of the platform's flagship products
→ Strong adoption among enterprise users
→ A scalable foundation for future features
04 · Blockchain Track-and-Trace Platform

Sojo Shield

Context. A real-time track-and-trace platform built on top of Oracle NetSuite. My job was adapting enterprise workflows for mobile and designing new desktop experiences for operational teams.

Insight. Manufacturing doesn't happen behind a desk: operators work across warehouses and production lines. The mobile experience was built around that context, not as a scaled-down desktop.

Solution. Navigation, hierarchy and interactions were redesigned for the mobile context, while keeping shared interaction patterns across devices.

→ Enterprise workflows became accessible beyond the desktop
→ Improved usability for operators on the floor
→ Consistency across desktop and mobile platform-wide

Looking Back

Designing enterprise software isn't about fitting more information onto smaller screens.

It's about understanding where people work, how they make decisions, and giving them the right information at exactly the right moment.
