# MARION MORANETZ (541) 507-7549 | Marion.m.moranetz@gmail.com | linkedin.com/in/melmarion github.com/melmarion | Open to Relocation --- Growth engineer who builds engagement systems grounded in behavioral science. Architect of Persuasion-Max, a mechanistic persuasion prediction engine calibrated on 126K human interactions. Built 80 products in 2 weeks — 14 casino games in a single session, a procedural open-world game with emotional creature AI, and 27 reusable engagement design systems. Looking for Growth Engineering roles where retention and engagement are engineered from behavioral principles, not guesswork. --- ## ENGAGEMENT SYSTEMS & GROWTH ENGINEERING ### ARCANE — 14-Game API Credits Platform | 2026 *Full casino platform with 14 provably fair games (Crash, Mines, Plinko, Blackjack, Duck Cross, Dragon Tower, Dice, Limbo, Pump, Keno, Wheel, HiLo, Flip, Snakes). Each game standalone HTML with canvas rendering and Web Audio. Built in one session.* - **Replicated Stake.com's engagement patterns**: auto-round countdown timers, session continuity hooks, loss-aversion cashout mechanics, streak indicators, and history chips that create social proof of activity. - **Implemented provably fair system** (SHA-256 outcome hashing) — the trust layer that converts skeptical users into depositing users. Every outcome verifiable. - **Designed VIP/rakeback tier system** (Bronze through Mythic) with escalating rewards — the retention mechanic that increases lifetime value by rewarding cumulative spend, not individual wins. ### Wild Hearts — Open-World Engagement System | 2026 *Procedural Canvas game with emotional creature AI, breeding, combat, and resource collection. Every engagement mechanic documented with behavioral science citations.* - **Engineered variable reward schedules** across 4 income sources: passive (timer-based orchards), active (hunting), discovery (treasure chests), and social (breeding). Unpredictable sources generate more dopamine than fixed (Schultz 1997). - **Built parasocial bonding loop**: creatures have emotional state systems (ears flatten when scared, eyes open with trust, blush at high mood). Behavioral science: endowed progress — 2 feeds and animals seek you out. 3 feeds and they follow permanently. - **Implemented combo system with escalating feedback**: 2x → SUPER → MEGA → ULTRA with screen shake scaling, particle count increasing, and sound pitch rising. Each tier triggers the next dopamine hit. ### 27 Engagement Design Systems (Claude Code Skills) | 2026 - **Gamification Architect**: 11-minute session model, 2 primary mechanic limit (>2 causes 35% abandonment), streak mechanics (+60% commitment), variable reward tiers (small/medium/jackpot on 30-90s/3-5min/1-3% schedules). - **DOSE Neurochemical Framework**: maps every engagement feature to its neurochemical target (Dopamine: anticipation/variable reward, Oxytocin: bonding/social proof, Serotonin: status/progression, Endorphins: flow/celebration). Includes exact hex colors, sound frequencies, and haptic timings per neurochemical. - **Kingdom Loop Designer**: collect-spend-defend-expand cycle with spending pain sweet spot (40-70% of current holdings), threat timing (60-70% abundance / 30-40% defense), and partial loss design (full wipe = quit, partial damage = another cycle). ### Persuasion-Max — Message Optimization Engine | 2026 - **400-cell technique x persona interaction matrix** revealing 21.8pp compliance spread. Applied to content optimization: auto-selects techniques per audience personality profile. - **Platform-specific effectiveness calibration**: Reddit favors self-disclosure (0.9) and storytelling (0.9); LinkedIn favors expert testimony (0.9) and evidence-based framing (0.85). Closed-loop system auto-updates ratings from observed engagement. - **126K human interactions processed**, discovering that linguistic features contribute +10pp AUC but technique binary detection adds zero incremental signal — the HOW matters more than the WHAT. --- ## PRODUCT DEVELOPMENT (80 REPOS) - **34 iOS applications** including 4 iterative versions of social skill training (measuring conversation effectiveness), idle builders with prestige loops (Jeju Island), and card-drafting games with scarcity psychology (Aftergreen: 15% golden / 5% mystery variant rates). - **39 browser-based projects** including influence detection tools, 14-game casino platform, propaganda analysis systems, and ambient generative experiences. - **7 Python systems** including Persuasion-Max, a 56-tool autonomous content agent (Social Pilot), and a 50-tool MCP marketing server. --- ## TECHNICAL PROFICIENCY **Growth & Engagement:** A/B testing, session architecture design, retention mechanics (streaks/VIP/rakeback), variable reward schedules, DOSE neurochemical framework, funnel analysis, loss-aversion optimization **Languages & Frameworks:** Python, Swift/SwiftUI, JavaScript/React, Canvas API, Web Audio API, FastAPI, scikit-learn, Matter.js **ML/AI:** LLM fine-tuning, Claude API, NLP feature engineering, logistic regression, prompt engineering **Behavioral Science:** Operant conditioning (Skinner), Zeigarnik Effect, Peak-End Rule, Fogg Behavior Model, cognitive appraisal theory, Moral Foundations Theory, Big Five personality modeling **Tools:** Git (80 repos), Xcode, VS Code, Claude Code, MCP protocol --- ## EDUCATION **Southern Oregon University** — B.S. Innovation & Leadership (3.76) | Minor: Rhetoric & Reason | 2025 **Southwestern Oregon Community College** — A.S. General Studies (3.8, top 5%) | 2023 --- ## KEY METRICS - 21.8pp persona compliance spread — same technique, dramatically different outcomes by personality - 14 casino games built in one session with engagement loops, sound design, and provably fair outcomes - 126K human interactions calibrated across 4 research datasets - 27 reusable engagement design systems with documented retention lift ranges - 414 automated tests, 302 documented model parameters
