Attention to Detail
I catch the edge cases others walk past, cross-referencing Figma against live builds across hundreds of screens.

Quality Mindset
I think in risk, coverage, and prevention. Quality is planned into the STLC, not inspected in at the end.
Technical Depth
API validation in Postman, on-chain flow checks, and smart-contract testing, not just clicking through happy paths.
Reliability
Independent ownership of the full STLC, shipping secure, high-quality software on schedule across 8+ products.
About
Quality isn't a phase. It's a mindset.
I'm a Software QA Engineer based in Islamabad with 2+ years delivering end-to-end quality assurance across web, mobile, and blockchain platforms. I've independently owned the full STLC, from test planning and execution to defect management and release sign-off, across 8+ live products in the Web3, DeFi, and AI sectors.
My work spans API testing, performance testing, and cross-platform validation. A dual background in project management means I collaborate closely with developers, designers, and stakeholders to ship secure, high-quality software on schedule, not just to log bugs after the fact.

Case Studies
Problem, approach, result.
Four products where full-STLC QA turned into shipped, dependable releases across web, mobile, and Web3. Each one carries an artifact from the actual work.
CS-01
10+ modules · 50+ screens verified
JONI — Personal AI Computer
Quecko Inc. · Web & Mobile · QA Lead
Problem
An ambitious AI platform spanning web and mobile, with 10+ feature modules, multi-step auth, a multi-chain payment system, and an AI agent marketplace, all needing quality coverage before release.
Approach
Led QA across all modules. Authored test plans and cases in TestRail covering functional, regression, smoke, UI/UX, and security. Validated multi-step authentication and the multi-chain payment flow end to end with Postman plus manual testing, and exercised the AI agent marketplace and enterprise dashboard.
Result
Ensured design fidelity across 50+ screens by cross-referencing Figma against live builds, logging UI defects in Jira with annotated screenshots. Shipped a complex multi-platform product with auth and payments validated end to end.
| ID | Title | Steps | Expected | Status |
|---|---|---|---|---|
| TC-014 | Valid login | Enter valid credentials, submit | Redirect to dashboard | Pass |
| TC-018 | 2FA / OTP step | Submit valid OTP within window | Session established, token issued | Pass |
| TC-022 | Session timeout | Idle past expiry, perform action | Re-auth prompt, no data loss | Pass |
| TC-031 | Multi-chain payment | Pay across two chains, confirm | Both txns reflected, balance correct | Review |
why it matters: Auth and payments are where trust is won or lost. Structured TestRail cases make that coverage auditable, not anecdotal.
CS-02
100+ screens · web/mobile parity
Gems Trade — Centralized Crypto Exchange
Web & Mobile · Full test strategy
Problem
A centralized crypto exchange on web and mobile where real-time market data accuracy and wallet security were non-negotiable, and any drift between platforms would erode user trust.
Approach
Designed and executed a comprehensive test strategy across all modules. Validated real-time market-data accuracy against source feeds, tested the multi-step wallet security flows, and verified feature parity and UI consistency between web and mobile.
Result
Confirmed feature parity and UI consistency across 100+ screens, web versus mobile, with market data and wallet flows validated for accuracy and security before release.
GEMS-2218
Critical
Market price freezes on mobile after websocket reconnect
why it matters: A reproducible ticket with clear expected-vs-actual is the difference between a one-sprint fix and a trader losing money on stale data.
CS-03
Full suite · performance & load tested
Gems Rocks — Memecoin Launchpad
Web3 · Token creation & bonding curves
Problem
A Web3 memecoin launchpad where token creation and bonding-curve mechanics had to behave correctly under load, with on-chain logic that fails loudly and expensively if wrong.
Approach
Built and executed a full test suite for token creation and bonding-curve mechanics, ran performance and load testing against the platform, and tracked defects through their lifecycle in Jira.
Result
Token-creation and bonding-curve flows validated for correctness and stability under load, with defects triaged and resolved before they reached users on-chain.
// Postman test script — validate bonding-curve quote
pm.test("Status is 200", () => {
pm.response.to.have.status(200);
});
pm.test("Quote price increases with supply", () => {
const body = pm.response.json();
pm.expect(body).to.have.property("price");
pm.expect(Number(body.price)).to.be.above(0);
pm.expect(body.supply).to.be.a("number");
});
pm.test("Slippage within tolerance", () => {
const { expected, quoted } = pm.response.json();
const slip = Math.abs(quoted - expected) / expected;
pm.expect(slip).to.be.below(0.01); // < 1%
});
smoke ✓
api ✓
load ✓
regression ✓
sign-off ✓
why it matters: On a launchpad, a wrong quote is real money lost. API-level assertions catch curve and slippage errors before they hit a wallet.
CS-04
All wallet APIs validated · security-first
Flash Wallet — Lightweight Crypto Wallet
Mobile · Full QA lifecycle owner
Problem
A lightweight mobile crypto wallet where a single unhandled API edge case could mean lost funds, requiring security-first QA across the whole product.
Approach
Owned the full QA lifecycle. Authored the test plan and complete test suite, validated all wallet API endpoints via Postman covering request/response, authentication, and error handling, and took a security-first approach to every flow.
Result
Every wallet API endpoint validated for correct responses, auth, and error handling, with the full suite documented and repeatable for future releases.
| Endpoint | Case | Expected | Status |
|---|---|---|---|
| POST /tx/send | Insufficient balance | 402, no broadcast | Pass |
| POST /tx/send | Invalid address checksum | 400, validation error | Pass |
| GET /balance | Expired auth token | 401, re-auth required | Pass |
| POST /tx/send | Network timeout mid-send | Safe retry, no double-spend | Review |
why it matters: In a wallet, the error paths are the product. Validating every failure mode is what makes "lost funds" a non-event.
