When I am useful
The existing product has become difficult to evolve.
Clarify the replacement or modernisation path while protecting essential operational behaviour.
Product intent gets lost between business, UX, and implementation.
Keep the decisions, workflow, experience, and delivery aligned from first idea to working software.
How I carry work forward
Find the real problem
Talk with the people who do the work, map the rules and exceptions, then agree what the product needs to achieve.
Make it usable
Shape the workflows, screens, permissions, and edge cases into an experience people can use in their day-to-day work.
Carry it into production
Choose a practical technical path, prototype where it helps, and stay close to implementation, release, and improvement.

“Over the last 3 years I’ve been working together with Sergii on various projects from first idea, a set of wireframes, MVP up to a fully functioning product …”

Practical product understanding, kept connected to delivery.
I am an independent Technical Product Manager based in Warsaw. My background combines end-to-end product delivery with earlier legal and business-process work, which helps me reason carefully about rules, risk, institutions, workflows, and regulated constraints. I work best where deep product understanding and practical delivery need to stay connected.
Technical context: Next.js/TypeScript, Flutter, Supabase/PostgreSQL, FastAPI/Python, APIs, CI/CD, and production monitoring.
Have a complex product or operational workflow to untangle?
I am open to contract, interim, fractional, and project-based B2B assignments. Send a short description of the situation, expected start, working model, and location.
