Clinical Wound Assessment App

QA for an FDA-regulated mobile application used by clinicians to photograph, measure, and track wound healing progress with AI-powered analysis. Nurses and wound care specialists in hospitals and home health settings relied on the app daily to document patient wounds and generate treatment reports. Because the AI measurements directly influenced clinical decisions, testing accuracy was not just a quality concern but a patient safety requirement.

The Challenge

Medical software has zero tolerance for errors. Incorrect wound measurements could lead to wrong treatment decisions, and the FDA submission required documented evidence of measure...

Global Fashion E-Commerce

Comprehensive QA for a celebrity-backed athleisure brand with millions of monthly visitors, complex subscription models, and international checkout flows. The storefront operated in 12 countries with localized pricing, currency conversion, and region-specific tax calculations. We built automated API test suites using PactumJS to validate all backend endpoints, payment integrations, and subscription billing APIs. We also built a custom AI-powered migration agent using GitHub Copilot that converted their entire legacy Python Robot Framework test suite into modern Playwright tests, saving months of manual rewrite work.

The Challenge

Flash sales drove massive traffic spikes that could hit 50,000 concurrent users within seconds of a product drop. The subscription model (VIP membership) had complex billing logic ...

VIP membership subscription billing cycles including trial conversions, pauses, and cancellations

QA for a Web3 platform that issues blockchain-based proof-of-attendance tokens, handling millions of claims across multiple chains and wallet providers. Event organizers used the platform to create unique digital collectibles that attendees could claim by scanning a QR code at physical or virtual events. QA was essential because failed minting transactions or duplicate token issuance would undermine the trust and value of the entire verification system.

The Challenge

Smart contract interactions had to work flawlessly across Ethereum, Polygon, and other chains, each with different gas models and confirmation times. Wallet connection flows varied...

Enterprise Learning & HR Platform

Long-term QA engagement for an enterprise learning management system used by 5,000+ organizations for employee training, compliance tracking, and performance management. The platform served everyone from 10-person startups to Fortune 500 companies, each with unique configurations and permission structures. QA mattered because compliance training failures could expose the client organizations to legal liability, and any data leak between tenants would be a dealbreaker for enterprise customers.

The Challenge

The platform served enterprise clients with strict SLAs requiring 99.9% uptime and sub-3-second page loads. Multi-tenant architecture meant a bug for one client could cascade acros...

Medical Professional Network

QA for a SaaS platform connecting medical professionals with pharmaceutical research opportunities, handling sensitive health data and regulatory compliance. Doctors used the platform to find and participate in clinical trials, while pharmaceutical companies used it to recruit qualified participants and manage study logistics. QA was essential because the matching algorithm directly influenced which doctors saw which trials, and any data handling error could violate HIPAA and expose the company to significant legal penalties.

The Challenge

The platform processed protected health information (PHI) and needed strict HIPAA compliance across every feature, from user profiles to messaging to document uploads. Complex matc...

DTC Beauty & Skincare Store

QA for a fast-growing direct-to-consumer beauty brand with international shipping, influencer-driven traffic spikes, and complex bundle pricing logic. The brand had a loyal following on social media, and every product launch was amplified by influencer partnerships that could drive tens of thousands of visitors to the site within minutes. QA was critical because the combination of bundle discounts, subscription savings, and promo codes created a pricing rules engine that was surprisingly easy to break.

The Challenge

Influencer campaigns drove unpredictable traffic spikes that could go from 500 to 30,000 concurrent users in under five minutes when a post went viral. Bundle pricing and discount ...

Web3 Investment Platform

QA for a decentralized investment platform enabling tokenized asset trading with smart contract-based settlement and multi-chain wallet support. The platform allowed users to invest in tokenized versions of real-world assets like real estate and commodities, with trades settling on-chain through audited smart contracts. QA was non-negotiable because every transaction involved real funds, and blockchain transactions cannot be reversed once confirmed.

The Challenge

Financial transactions on blockchain are irreversible, so smart contract bugs could lock user funds permanently with no way to recover them. The platform needed to handle volatile ...

Smart contract audit and edge case testing including overflow, underflow, and precision loss scenarios

Freight Management SaaS

QA for a cloud-based freight management platform used by trucking companies to manage dispatching, invoicing, driver tracking, and compliance documentation. Small and mid-size carriers relied on the platform to run their daily operations, from assigning loads to generating BOL documents to collecting payment. QA was critical because invoicing errors could mean trucking companies under-billed their customers, and compliance documentation mistakes could result in DOT fines or trucks being taken out of service.

The Challenge

The platform managed real-time GPS tracking of hundreds of vehicles simultaneously, with location updates flowing in every 30 seconds that needed to be processed, stored, and displ...

Telehealth & Patient Portal

QA for a telehealth platform enabling virtual consultations, prescription management, and patient health record access across web and mobile. Patients used the platform to book appointments, have video consultations with their doctors, receive prescriptions, and access their health records from anywhere. QA was critical because a failed video call meant a missed medical consultation, and any error in the prescription workflow could have direct patient safety consequences.

The Challenge

Video consultation quality had to be reliable across varying network conditions, from broadband connections to rural cellular data, because patients in underserved areas were a key...
