Braze Integration and Cross-Platform Engagement Strategy
Brainly — Product Owner
Brainly needed a robust engagement automation platform to support scalable user communication across push notifications, in-app messaging, and email — all localized and behavior-triggered across platforms.
The engagement stack was outdated, non-personalized, and inefficient to scale across Brainly’s 350M+ user base.

Strategic Vision for a Personalized, AI-Driven Learning Experience
Brainly — Marketing Strategist
Brainly needed to evolve from a high-traffic homework Q&A platform into a more engaging, indispensable learning companion.
This self-initiated vision work aimed to define what that transformation could look like through a structured, personalized, and AI-augmented study experience.
Despite its scale, Brainly’s user experience was transactional — users came for one-off answers rather than long-term study support.
The opportunity was to design a product direction that shifted from isolated queries to structured, session-based learning journeys, aligning with user behavior, retention, and educational value.
- Conducted research to map user pain points and emotional friction in the current experience.
- Analyzed competitor platforms and user motivations to uncover opportunities for differentiation.
- Designed a modular product framework centered on guided “study sessions” combining AI-generated support, user goals, and progress tracking.
- Proposed features such as dynamic content personalization, dual-model answer comparison, citation generation, paraphrasing tools, and learning analytics dashboards.
- Integrated AI into user workflows not as a gimmick, but as a tool for confidence-building, clarity, and reduced cognitive load.
- Created a phased rollout roadmap, including MVP scoping, adoption strategies, and UX principles for long-term engagement.
- Delivered a complete strategic blueprint for platform evolution, presented to internal stakeholders.
- Elevated internal discussion around long-term product direction, AI integration, and session-based learning value.
- Positioned the platform to explore deeper engagement models beyond reactive Q&A loops.
Student Experience Research and Pain Point Mapping
Brainly — Product Manager
As Brainly matured, it needed a deeper understanding of its student users’ emotional journey — beyond surface-level metrics — to inform more engaging, trust-building, and learning-focused product strategies.
Product teams lacked a clear map of how students experienced the platform emotionally and cognitively.
This created misalignment between feature delivery and actual user needs — especially in moments of frustration, uncertainty, or disengagement.
The opportunity was to synthesize a comprehensive student experience map to guide strategic priorities and product narratives.
- Designed and executed a mixed-method research initiative combining in-depth interviews, guided user testing, behavioral surveys, Hotjar recordings, and session replays.
- Analyzed user behavior across different journey stages — first contact, repeated use, disengagement, frustration, churn — to identify key inflection points.
- Led synthesis workshops with Product, Design, and Growth teams to align findings to platform decisions.
- Produced a visualized journey map connecting emotional states, behavioral patterns, and product interactions.
- Framed opportunity areas for feature ideation, UX adjustments, and AI augmentation grounded in real user struggles.
- Delivered actionable research assets used in multiple product and marketing team roadmaps.
- Revealed blind spots in product assumptions, shifting roadmap priorities toward learning support and frustration mitigation.
- Informed the development of multiple new features aimed at increasing trust, reducing confusion, and reinforcing engagement.
- Reframed internal product language around student motivation, cognitive load, and emotional states.
- Became the foundation for broader initiatives exploring learning sessions, motivational design, and AI-based support.
Redesign of the User Ban Experience for Fairness and Trust
Brainly — Product Manager
Brainly’s automated moderation and ban systems were functionally effective but often perceived by users as opaque, arbitrary, or unfair — undermining platform trust and increasing support ticket volume.
Users who were banned (often for violating content or behavior policies) received minimal context or guidance, resulting in confusion, frustration, and unnecessary churn.
The opportunity was to redesign the entire ban experience — from messaging to appeals — to increase clarity, reduce repeat violations, and preserve user trust even during enforcement.
- Audited the existing ban triggers, messaging flow, and user-facing touchpoints across platforms.
- Proposed and implemented a tiered penalty system with escalating consequences tied to user behavior history.
- Designed new UX patterns including clear messaging on cause, ban duration, and user recourse options.
- Integrated the system with Zendesk to generate automatic tickets for review, reducing response latency and support overhead.
- Added educational content and community guideline links to all ban-related communications.
- Aligned enforcement flows with user sentiment data and legal/privacy guidelines.
- Reduced repeat ban rates through clearer warnings and educational interventions.
- Improved user perception of fairness in platform enforcement — confirmed via support feedback and user interviews.
- Lowered support team workload by automating ban-related ticketing and triage.
- Strengthened Brainly’s moderation framework without alienating borderline users.
Exploration of a Dynamic Metering System for Monetization Optimization
Brainly — Product Manager
As Brainly looked to evolve its freemium model, static access limits (e.g., fixed paywalls after X answers) created blunt user experiences and left revenue on the table.
There was a need to explore more nuanced, behavior-based metering to balance engagement and monetization.
The existing access model treated all users the same, regardless of behavior or intent — either offering too much for free or pushing away high-value users too early.
The opportunity was to design a dynamic metering system that adjusted content access thresholds based on user behavior, predicted conversion potential, and platform value delivery — increasing monetization without harming engagement.
- Conducted exploratory research on metering strategies used by subscription-based content platforms (media, edtech, productivity).
- Designed a scoring algorithm using behavioral inputs (session depth, feature usage, engagement history) to dynamically assign access thresholds.
- Proposed content gating flows (e.g., adwall, soft paywall, reward-unlock gates) tailored to user clusters.
- Used principal component analysis (PCA) and engagement signals to simulate user segmentation for prototype testing.
- Outlined experimental design for phased A/B testing, including fallback conditions and sensitivity analysis for impact on churn, engagement, and LTV.
- Delivered a full spec doc including architecture, scoring logic, threshold calibration strategy, and success metrics.
- Provided a technically and behaviorally grounded framework for adaptive monetization experimentation.
- Shifted internal thinking away from fixed thresholds toward intent-driven gating models.
- Enabled future pilots of metering strategies aligned with personalization and AI scoring tools.
- Positioned Brainly to scale monetization intelligently without compromising trust or learning outcomes.
Personalized Year-End Learning Summaries for Engagement and Retention
Brainly — Product Owner
To boost engagement and reinforce Brainly’s value as a learning companion, the team developed a year-end feature that celebrated user progress and encouraged reflection and return use.
