Igor DyakovProduct design & UX research for workflow-heavy B2B systemsigor@igordyakov.com

I design complex B2B products people use to get real work done

I work with interconnected workflows, domain rules, large amounts of data and years of accumulated product decisions.

My job is to make that complexity usable without simplifying away what the product actually needs to do.

Where I can helpThree situations I’m usually brought in for

Your product works. Its UX needs to catch up.

Products grow feature by feature. Over time, workflows become inconsistent, patterns diverge and everyday tasks get harder than they need to be.

I help bring the experience back together — gradually improving workflows, interactions and design patterns without breaking what existing users already rely on.

Your foundation is solid. Your team needs reinforcement.

You already have a product, design logic and people who know the domain. What you need is experienced design capacity.

I can take ownership of a product area, work within the system you already have and collaborate directly with product and engineering without adding management overhead.

You're building something new and need to know what works.

An idea, prototype or early product comes with a lot of assumptions.

I combine research and product design to identify the important ones, test them with the right users and turn what we learn into a stronger product direction.

Latest projectsMostly under NDA, happy to walk you through it

Client work involves sensitive results, data and process insights, so the details stay out of public view, out of respect for clients and partners. Ask, and I’ll send case studies that fit what you’re working on or go through them with you on a call.

BackgroundFrom systems analysis to teaching 1,000+ practitioners

I originally studied systems analysis and applied mathematics at Zaporizhzhia Polytechnic, which probably explains some of my attraction to products with complicated logic.

I’ve also spent seven years teaching practical product design and research, working with more than 1,000 practitioners through corporate programs for PrivatBank, Nova Poshta, Kyiv Digital, PandaDoc and others. In 2023, I spoke at HCI International in Copenhagen.

Alongside product work, I’m doing PhD research into how digital product designers develop professional competency.

Teaching, it turns out, is one of the best pressure tests for thinking: explaining something to a thousand people forces you to actually understand it.
