Haseeb M.

QA Engineer with $2K+ earned and 194 hours on Upwork — I've shipped quality on production SaaS, AI/LLM platforms, payment systems (Stripe, Flapjack), and loyalty/engagement engines. 9 contracts, zero refunds. I help SaaS founders and product teams ship reliable software across web, mobile, APIs, payments, and AI features — manual + automation, with the kind of bug reports your devs will actually thank you for. Products I've tested end-to-end: 🤖 SanaLabs — enterprise AI assistant with multi-model support (GPT, Claude, and other LLMs). Tested model switching, response consistency across models, prompt handling, context retention, file uploads, streaming responses, and Stripe subscription billing. 🍽 CafeZupas (Web + Mobile) — restaurant ordering platform. Owned: • Loyalty/rewards engine testing using Braze and Session M — points earning, redemption, tier transitions, expiry rules, segmentation triggers • Full Stripe payment flow — cards, Apple Pay, refunds, partial payments, 3DS, failure-path UX • Push notifications on iOS & Android — delivery, deep links, segmentation, payload validation • Headless API testing for third-party integrations exposed to Uber Eats and DoorDash (no UI involved) — schema validation, auth, rate limits, error responses, order sync 💳 Flapjack — payment/billing platform. End-to-end payment flow testing, edge cases, and reconciliation. 🛠 CMMS Platform — full product testing of a Computerized Maintenance Management System (work orders, assets, scheduling, role-based permissions, reporting). 🚀 Appical — employee onboarding SaaS, web + mobile app. Functional, UX, and cross-device testing.

I'll ask the questions your dev team would want answered. If your product touches AI, payments, loyalty, push, or third-party APIs, we're a strong fit. Open to hourly or fixed-price — happy to do a small paid trial bug-hunt before committing.
