Product owner of Bitnbox — crypto payment infrastructure letting businesses accept, convert and settle payments across major blockchains and stablecoins (USDT, USDC), delivered through a REST API, hosted checkout and no-code payment links. - Own the product backlog and roadmap across the full merchant journey: onboarding and KYB, integration, checkout, settlement and payouts - Gather and structure requirements from merchants, integration partners and internal compliance; translate them into user stories with acceptance criteria and process diagrams for the engineering team - Prioritize the backlog against revenue impact and integration effort (RICE), manage scope and delivery risk, and run sprint planning and acceptance with engineering, design and analytics - Design payment flows across all three integration models — API, hosted payment page and shareable links — balancing conversion against the security constraints of on-chain settlement - Own the developer experience as a product surface: API reference and Swagger documentation, webhook contracts, SDK and plugin coverage, and time-to-first-successful-payment as a tracked metric - Define product requirements for multi-chain settlement, stablecoin conversion and volatility protection, working with engineering on chain support prioritization and liquidity constraints - Specify edge-case recovery flows, including funds sent on the wrong chain — turning a common merchant support burden into a self-service product feature - Partner with compliance on AML and fraud controls, designing screening and risk rules into the payment flow so they hold without degrading legitimate merchant conversion - Own the fee model and unit economics: take rate across transaction tiers, withdrawal fees, enterprise pricing, and gross margin per merchant segment - Drive third-party payment integrations (Binance Pay, KuCoin Pay) from partner evaluation through to production release - Define and track the product metrics framework: total payment volume, checkout conversion rate, settlement success rate, integration completion rate, merchant activation and retention, ARPPU Key results: - Grew total payment volume 4.5× — from $2.1M to $9.4M per month over 12 months, while holding the blended take rate at 0.9% - Onboarded 120+ merchants, with the top 20 accounts driving 70% of volume; shifted the acquisition focus to high-volume enterprise after unit-economics analysis showed a 6× difference in LTV between segments - Raised merchant activation (signup → first live payment) from 34% to 61% by rebuilding onboarding and KYB into a staged flow, cutting the drop-off at document submission in half - Cut median integration time from 9 days to 2 through rewritten API documentation, a Swagger sandbox and ready-made plugins — removing the single largest reason merchants stalled before going live - Increased checkout conversion from 71% to 84% by redesigning the payment page around confirmation-wait expectations, the point where most abandonment occurred

Core game designer on Run away from me: Alexandra — a first-person psychological horror in which the player, abducted and held in a killer's country estate, must escape a staged "hunt." The project's defining design constraint: no conventional HUD. The entire interface is diegetic, living inside a fitness bracelet and phone that carry the flashlight, inventory, breathing and pulse. - Designed the diegetic interface system that defines the game. Breathing and pulse are not readouts but live mechanics — the player's physiological state determines whether hiding succeeds, making tension a system the player must actively manage rather than a mood the game imposes - Designed and balanced the core loop — exploration, stealth evasion and puzzle-solving — tuning survival pacing across locations so that threat density, safe-route availability and hidden-item placement sustain pressure without exhausting the player - Designed the branching decision architecture leading to multiple endings, ensuring choices carry consistent narrative and mechanical consequence rather than cosmetic variation - Designed tension-signalling feedback, including the eye-blink visual effect used to communicate danger states without breaking first-person immersion - Built scenes and cinematics in Unreal Engine 5, implemented gameplay logic through Blueprints, assembled prefabs from 3D assets, and worked with level designers to translate mechanics into interactive location layouts with alternate routes - Authored the Game Design Document with the producer — core loop, mechanics, character and visual concepts — serving as the shared reference for narrative, art and engineering - Integrated logic puzzles into the narrative so that problem-solving advances the story rather than interrupting it - Collaborated cross-functionally with narrative, art and design teams to hold story and systems together as one coherent experience Key results: - Shipped a playable Steam demo, validating the diegetic interface concept with real players - Delivered the game to a three-language release scope (EN / RU / JA), with design and UI built to survive localization - Established the GDD as the studio's single source of truth for the project, aligning narrative, art and engineering on shared terminology
