Case Studies

Real Problems.
Real Fixes.

We don't just write test cases. We solve business problems caused by technical instability. Here's the work.

Blockchain / Fintech

Stablecoin & Crypto Payments Platform

Reducing Transaction Failures by 28% in High-Volume Crypto Payments
⚠️The Problem

The platform was experiencing a high rate of silent transaction failures during peak volatility. Users were being charged gas fees for failed transactions, leading to massive support ticket volume and user churn. Their manual QA process couldn't simulate realistic blockchain network congestion.

🔧What We Fixed
  • ✓
    Implemented automated on-chain simulation testing using forked networks
  • ✓
    Created a synthetic transaction generator to stress-test payment gateways under high-load/high-gas scenarios
  • ✓
    Built real-time alerting for 'stuck' transactions to trigger automated retry logic before user failure

Deployment Speed

"Transaction success rates stabilized, reducing customer support costs by 40%. The engineering team moved from 'fear-based' weekly releases to confident daily deployments."

Wealth Management

Paytm Money — Wealth Management

Scaling Quality for 6.5M+ Daily Active Users
⚠️The Problem

As Paytm Money scaled rapidly from early adoption to millions of users, the legacy testing infrastructure crumbled. Regression testing took 3 days manually, meaning critical market-timing features were delayed. Crashes during market opening hours were eroding trust.

🔧What We Fixed
  • ✓
    Architected a parallelized automation framework that reduced regression time from 3 days to 4 hours
  • ✓
    Implemented 'Chaos Engineering' for market-open spikes to ensure order execution systems never froze under load
  • ✓
    Shifted quality left by integrating API contract testing into the developer PR workflow

Payments / POS

Paytm — Payments, PG & POS

Improving Payment Success Consistency at National Scale
⚠️The Problem

Inconsistent payment success rates across different banking networks and POS devices were hurting merchant trust. 'False negatives' (where money was deducted but payment showed failed) were the biggest pain point.

🔧What We Fixed
  • ✓
    Developed a multi-rail reconciliation test suite to verify payment statuses across issuer, acquirer, and network layers
  • ✓
    Automated physical POS testing using robotic arms and simulated card inputs for hardware reliability
  • ✓
    Created an intelligent routing test matrix to identify and isolate underperforming bank gateways in real-time
