Product & Data Analyst — Case Study Portfolio

// finds where users drop off, then rebuilds the flow so they don't

I spend most of my time in funnels — the ones users abandon and the ones products live or die by. Give me session logs, a query editor, and a drop-off number, and I'll tell you where it's happening, why, and what to ship next.

Case Studies

Three funnels, three fixes

Each entry below follows the same shape: what the data showed, what I changed, and what moved. Tags mark whether the impact is measured in production or modeled from cohort assumptions.

Mid-Session Drop-off, All India Gaming Federation

Measured
PRD‑01 · Data Analyst Internship · Aug–Oct 2025
Problem

High-value players were vanishing mid-session, and nobody knew exactly where. I pulled 20K+ gameplay sessions with SQL and Excel to find the moment.

Analysis

Cleaned and validated the underlying event data first — reporting was only as trustworthy as the pipeline feeding it — which lifted data accuracy by 25% and made every downstream number defensible.

Solution

Built interactive dashboards tracking retention, session length, and revenue side by side, so product and business teams could watch the drop-off point instead of debating it.

Session start100%
Reached mid-session engagement point82%
18% of high-value users dropped off right here
Shipped Impact+12% user engagement

Swiggy Onboarding Optimization

Modeled
PRD‑02 · Independent Case Study · Feb 2025
Problem

I mapped Swiggy's onboarding funnel in Excel/SQL and found 35%+ of users dropping off during the login and location-permission steps — right before first order.

Solution

Redesigned the flow around guest browsing, cutting the path from 5 steps to 3, using the funnel data and UX heuristics to decide exactly which steps to remove rather than trim arbitrarily.

App opened100%
Login + location permission (as-is)65%
35%+ drop-off across these two steps today
Onboarding complete (3-step redesign, projected)~82%
Modeled Impact+15–20% completion · −12% time-to-first-order
What I'd do differently
  • Validate the projection with a real A/B test instead of relying on cohort simulation alone.
  • Track activation and Day-7 retention after rollout, not just completion.
  • Pair the funnel data with qualitative feedback to catch friction the numbers miss.

E-commerce Product Analytics & Optimization

Modeled
PRD‑03 · Independent Case Study · Dec 2024
Problem

10K+ transactions held a story about which categories converted and when — but no one had segmented it by time.

Solution

Built time-based demand models in SQL/Excel to flag peak conversion windows, then used them to steer inventory allocation and dynamic pricing toward the moments that mattered.

Off-peak conversion rate (baseline)100%
Peak-window conversion, after re-allocation+10–15%
Modeled Impact+10–15% conversion · +8% revenue per user
What I'd do differently
  • Validate the pricing and inventory recommendations with live experiments before full rollout.
  • Segment users by cohort and purchase frequency rather than treating demand as uniform.
  • Measure downstream effects on retention and customer lifetime value, not just conversion.

Swiggy Onboarding Optimization

Draft PRD
PRD‑04 · Companion spec to Case Study PRD‑02
Goal

Reduce onboarding friction and increase the share of new users who complete onboarding and place a first order.

Target User Inferred

New users installing the app for the first time, particularly those dropping off at login or location-permission.

Success Metrics
  • Onboarding completion rate (from case study)
  • Time-to-first-order (from case study)
  • Activation rate, per-step drop-off, guest-to-registered conversion, Day-7 retention Inferred
In Scope
  • Guest browsing before account creation
  • Reducing onboarding from 5 steps to 3
  • Reworking the login and location-permission steps
Out of Scope Inferred
  • Payment flow
  • Restaurant discovery & recommendation engine
  • Checkout experience
Risks & Edge Cases Inferred
  • Guest users may convert to registered accounts at a lower rate than users onboarded the old way.
  • Delaying location permission could weaken early restaurant-recommendation relevance.
  • Some downstream features may still force account creation earlier than the new flow intends.

Rollout Plan Inferred
Phase 1
Internal testing
Phase 2
10% user rollout
Phase 3
A/B test vs. current flow
Phase 4
Full rollout if KPIs improve
Why Product

Why I want to do this

My work has consistently centered on using data to understand user behavior and improve outcomes. During my internship, I analyzed gameplay data and built dashboards that shaped product decisions, and my independent case studies came from the same instinct: find where users get stuck, then figure out what to change. Over time I noticed I wasn't satisfied just naming the problem — I wanted to decide what got built to fix it. Product management is that combination: analytical thinking, user empathy, and cross-functional decision-making, aimed at outcomes that matter for both users and the business.

Draft — I'm still refining this in my own words
