Product Experience

ruhly Founding Product Manager (pre-launch app)

  • Scope: cut the Ramadan v1 to four features and moved the Quran reader, social feed and B2B tools to after launch, so a small team could ship a polished core on a fixed date. Set launch KPIs: D7 retention, K-factor, free-to-paid conversion. Pre-launch, so results come after release.
  • Streak tradeoff: the streak counted a tap, so a 300-day streak could mean nothing was read. It now counts only once a passage has been open long enough to read: a lower number, but an honest one. Added banked rest days so one missed day doesn’t wipe out a habit.
  • Paywall: kept it dismissible, never a hard gate. Cut two advertised features that didn’t exist yet and rewrote the rows around what users feel, not our feature list. Designed ruhly+ (RevenueCat), a Stripe donation checkout, and a two-tier referral program.
  • Trust: cut onboarding from 11 screens to 8 and flagged the dropped under-13 age gate as an open compliance call. A religious content review I ran before launch caught a bug labelling four ordinary days a year as Eid.

BeReal x Extern Product Management Extern

  • Mapped the funnel with AARRR and found 6 friction points. The real gap was retention: only a daily notification brought people back.
  • Compared TikTok, Instagram, and Snapchat, then proposed friend streaks to give users a social reason to return.
  • Prototyped the feature and ran moderated tests, where 82% of tasks were completed successfully.

Vosyn AI Product Manager Intern, Rotation II

  • Stepped in to lead internal automation for 3 departments after the PM left. Interviewed each team and ranked requests by hours saved against effort.
  • Started with the founders’ dashboard, which was updated by hand from Notion to a spreadsheet to Power BI, and automated it in n8n. Across all projects, saved 120+ hours of manual work a month.
  • Launched an SOP library and internal LLM chatbot (owned prompts and retrieval). Internal tool adoption grew 45%.
  • Rewrote user stories to be shorter and outcome-first after engineer feedback; sprint delivery reached 91%.

Vosyn AI Product Manager Intern, Rotation I

  • Owned the co-watching product built on Vosyn’s real-time AI translation engine, which keeps the nuance and emotional tone of dialogue for content like anime.
  • Shaped the core experience: users queue videos, pick their language, and watch together in moderated community spaces.
  • Worked with Engineering, Design, QA, and AI teams in two-week Scrum sprints.

Projects

Words With Friends FTUE Redesign ↗ Onboarding Teardown, Live Prototype & Test Plan

  • Played through the iOS first-time experience and found 4 points where new players drop off before day 1. Ads came up in 58% of 450 recent negative App Store reviews.
  • Redesigned the first match with one “Play your first word” button, 3 in-context tips, a balanced starting rack, and no ads, giving up first-session ad revenue to protect D1 retention.
  • Built a playable web prototype (real rules, 80K-word dictionary), a spec with 8 acceptance criteria, and an A/B test plan.

ProdHealth ↗ Open-Source Tool for AI Product Quality

  • Free browser tool linking thumbs-down feedback to the model or prompt change behind it; flags releases that fail a 24-question test.

PM-OS ↗ AI Workflow for Product Managers

  • Chains 6 AI agents to take a product problem from research to a reviewed PRD and clickable prototype (Next.js, Vercel).

Work Experience

  • Triage calls, emails and alarms from 900+ branches at BMO’s security intake centre using access control and CCTV, and resolve or escalate incidents within SLA.
