Ways to work together.

Focused product design and prototyping engagements for teams that need clarity, validation and implementation-ready artifacts.

S1, Sprint

Product Prototype Sprint

Turn an idea, feature or product concept into a realistic prototype that can be tested, presented or handed over to engineering.

Best forNew product ideas · MVPs · feature concepts · stakeholder alignment · investor demos
Typically 1–2 weeks
Best whenYou need alignment before committing engineering budget.
What you get
UX concept
User flows & core screens
Realistic prototype
Optional coded prototype
Next-step roadmap

S2, Sprint

AI Product UX Sprint

Design AI-powered workflows that are useful, controllable and understandable, beyond the default chatbot interface.

Best forAI copilots · agent workflows · document intelligence · decision-support systems
Typically 1–3 weeks
Best whenThe model exists, but the product experience around it is unclear.
What you get
AI interaction model
UX flows
Trust & control patterns
Fallback states
Prototype & validation plan
Design an AI workflow →
S3, Project

Design System & Frontend Accelerator

Create or improve interface systems that bridge design and implementation.

Best forInconsistent interfaces · slow handoff · scaling teams · Figma-to-code gaps
Typically 2–6 weeks
Best whenDesign and code keep drifting apart as the team scales.
What you get
Design system audit
Component structure & tokens
Documentation
Figma / code alignment
Prototype-ready component logic
Improve your design system →
S4, Discovery

UX Research & Product Discovery

Understand users, workflows and product risks before building the wrong thing.

Best forUnclear user needs · complex workflows · product risk · early validation
Flexible scope
Best whenYou’re not yet sure you’re building the right thing.
What you get
Stakeholder & user interviews
Workflow mapping
Problem framing
Opportunity areas
Prototype test plan
Start with discovery →

FAQ

Common questions.

Complex digital products: B2B SaaS, deep-tech and industrial tools, data products, AI workflows, dashboards, internal systems and professional software where information density and product judgment matter.

Both. I work with founders and small product teams as well as corporate innovation groups and established product organizations. The common thread is product complexity, not company size.

Yes. Beyond high-fidelity design prototypes, I build frontend-near, coded prototypes when realism, interaction or technical feasibility needs to be proven before development.

Yes. Confidential work is the norm. Sensitive cases are presented privately, and detailed metrics or screenshots are only shared with approval.

I bridge both. I prepare components, documentation and implementation logic, and collaborate closely with engineering teams to keep design and build aligned.

A focused 1–2 week engagement: align on goals and constraints, structure the product logic and flows, build a realistic prototype, then use it to test assumptions and define next steps.
