📈 Data informed (MA in Economics) + ❤️ User Obsessed (UX Certification) + 👷‍♀️ 10+ years hands-on experience Hi, I’m Kasia 👋 I help startups and growing companies transform ideas, complex requirements, and stalled products into actionable plans and delivered solutions. I am a Product Manager with 10+ years of experience across technology, product, and integrations, specializing in product discovery, UX research, strategy, and execution. I collaborate with founders, stakeholders, customers, and engineering teams to turn complex ideas and user challenges into clear product decisions, requirements, roadmaps, and delivered solutions. My approach is research-driven and practical. I use Jobs to Be Done (JTBD), customer interviews, usability testing, continuous discovery, experimentation, and analytics to understand user needs, then translate these insights into actionable business and engineering priorities. I can help with: 🔎 Discovery & Validation - Customer interviews and JTBD - Problem-solution fit and feature validation - Usability testing and user journey analysis - Qualitative + quantitative research - Competitor and gap analysis 🧭 Product Strategy - Product vision and value proposition - MVP definition and product positioning - Roadmaps and prioritization - Activation, retention, and PLG opportunities - Success metrics and experiments 🚀 Product Delivery - Translating business and user needs into clear requirements - Backlog management, user stories, and acceptance criteria - Cross-functional collaboration with Engineering, Design, Marketing, and Operations - Product implementation, testing, UAT, and go-live - Coordinating external developers, agencies, and vendors 🔌 Technical & Platform Integrations - REST APIs, webhooks, data flows, and third-party integrations - Payment and subscription platforms including Stripe, Chargebee, and RevenueCat - Analytics implementation with Mixpanel, GA4, and Amplitude - Mobile and web product delivery A few things I’ve done • Increased product activation from 33% to 47% through JTBD research, usability testing, and product improvements. • Took over a MedTech platform shortly before a contract-critical launch, identified key blockers, coordinated a cross-functional team, and delivered on time - securing the deal. • Designed and led the implementation of teleclinic, booking, marketplace, and multi-persona workflows that supported a B2C → B2B strategic pivot. • Led the onboarding redesign for a wellness platform, using customer research and JTBD to improve activation and engagement by 15%. • Partnered with 25+ startups and scaleups across SaaS, TravelTech, HealthTech, AI, and Wellness. What clients say “Super talented Product Manager with UI/UX acumen. If you’re launching a new product, she’s your go-to expert.” “Her product and UX ability were critical—she took us from just an idea to full delivery. We’d hire her again in a heartbeat.” “Kasia is an excellent communicator, and her work ethic is commendable.” I am especially effective when you need to validate a product idea, prioritize what matters, and turn insight into product clarity.
