Angle
I lead and support design teams building systems that are fun, readable, and sustainable to operate: progression, rewards, economies, and live cadence. I also offer gamification consultation for products outside games (NDA-friendly), focused on motivation, learning, and long-term engagement without dark patterns.
What I Deliver
- Game/system vision that translates into implementable specs and backlogs.
- Progression and economy audits with concrete improvement plans.
- Engagement loop tuning (onboarding, goals, challenges, rewards, cadence).
- Playtest and telemetry feedback loops (hypotheses, success criteria, rollout).
- Cross-functional alignment: design that ships, scales, and is understandable to teams.
Gamification Consultation (NDA)
I’ve supported non-disclosed work across health, learning, and platform experiences. Typical engagements include:
- Health & wellbeing apps: habit loops, streaks, progression, and sustainable rewards.
- Learning apps & platforms: mastery paths, challenges, pacing, and feedback clarity.
- Creator/platform products: onboarding, long-term retention, and incentive alignment.
- Ethical engagement: avoid exploitative patterns while still supporting business goals.
