References

Worked with YC-backed and high-growth startups on onboarding, product and MVP builds.

Filip was amazingly helpful for us. Helped us revamp our entire onboarding flow and managed to get insights intuitively that took us months of talking to users. Highly recommend working with him

Ayush, CEO @ Autumn

I’ve seen Filip turn loose ideas into focused plans and ship reliably. Sharp product sense, clear planning, and punctual. A strong asset to any team!

cool guy, pretty much capable of anything. ive seen him turn a random idea into a full, polished app in only a few weeks.
