From a raw idea to product–market fit.

Ran a fully-automated global affiliate service with a CPA network under the hood — took it from a raw hypothesis to found product–market fit over three years. Led cross-functional teams on Agile & Kanban; owned discovery, roadmap planning, CJM and deep CustDev/JTBD interviews with publishers; built a gamified retention loop. Project capitalization reached $1.5M.

Drove funnel growth for the Telegram mini-app (TMA) ecosystem — a multi-million global audience. Market analysis, feature-rollout planning, backlog grooming and a large volume of quantitative tests. Co-designed and documented the API incl. the TMA 2.0 spec, and rebuilt the docs structure data-driven from user behavior & integrator feedback so it reads and parses cleanly.

Product strategy, growth & delivery across several B2B SaaS products. In a goods-accounting SaaS for marketplace sellers (Topseller) I lifted core metrics via gamification, referral scenarios and AI-assisted onboarding → 82% 30-day retention, 56% referral. In a real-estate CRM (Vladis) I designed an internal messenger as the core workflow, ran downmarket adaptation to SMB and a legacy audit. Litebox — AI customer support up to L2 on GPT/Claude API + RAG. Plus a 0→1 mobile subscription launch (MeditationSteps) with multi-currency payments.

One-off and project-based consulting engagements. An international VPN product under constant blocking: alt-acquiring + crypto as backup payment rails, closed unit-economics, a year-ahead plan around regulatory risk. A top-10 iGaming product: retention & engagement for the VIP/whale segment — progression, loyalty and protective mechanics against abuse at the top tier.
