Available for senior QA & SDET roles
Senior SQA Engineer specializing in Test Automation, API Testing, Performance Testing, and Quality Engineering.
I help product teams ship reliable software by building maintainable automation, validating APIs and system performance, and turning quality into a measurable part of the delivery process — across fintech, ERP, e-commerce, POS, CRM, CMS and SaaS platforms.
About me
I'm a Senior Software Quality Assurance Engineer with 6 years of experience helping teams ship web apps, APIs and business platforms with confidence.
My focus is test automation, API testing and performance testing. I design automation frameworks that teams can actually maintain, integrate them into CI/CD pipelines, and use risk-based test strategy to put effort where defects would hurt users the most.
I work closely with developers, product managers and stakeholders from requirement review through release — so quality is built in early rather than inspected at the end.

How I can help
For product teams that want faster releases without trading away reliability.
Maintainable UI and API automation with Playwright, built to run on every pull request in your CI/CD pipeline.
Contract, functional, negative and authorisation testing of REST APIs, automated so regressions surface before release.
Load, stress and soak tests with clear baselines, so you know how the system behaves before your users find out.
Risk-based test strategy, test plans and quality gates that fit an agile delivery cadence.
Smoke and regression suites plus release sign-off criteria that keep every deployment predictable.
Automation code reviews, test-design coaching and shared QA standards for growing teams.
How I work
From the first user story to production, quality is planned, automated and measured — not left to the end.
Review requirements, user stories and acceptance criteria with the team; surface ambiguities and risks early.
Output: Clarified stories, risk list
Define a risk-based test strategy: scope, priorities, environments, test data and entry/exit criteria.
Output: Test strategy & plan
Design test cases and build UI, API and performance automation that runs in CI on every change.
Output: Test suites, CI pipeline
Run functional, regression and performance tests; log clear, reproducible defects and share progress.
Output: Defect reports, dashboards
Support release sign-off, verify in production, and feed metrics and escaped defects back into the process.
Output: Sign-off, quality metrics
Technical skills
A pragmatic toolkit chosen for reliability, maintainability and fast feedback.
Professional experience
From manual and cross-browser testing to leading test strategy, automation and performance testing for web and API products.

Featured QA projects
Client names and confidential details are omitted. Each case study describes scope, responsibilities and approach.
Fintech
Customer-facing financial application where transaction accuracy, security and reliability are critical.
Approach: risk-based prioritisation of money-moving flows, boundary and negative testing, data reconciliation with SQL.
Result: Zero critical defects in production across 12 releases; regression cut from 3 days to 6 hours
SaaS Payment Gateway
Multi-merchant payment processing platform with checkout, refunds, webhooks and merchant dashboards.
Approach: contract-driven API tests, sandbox-based integration testing and load profiles modelled on peak traffic.
Result: Payment APIs validated at 500 TPS with p95 under 300 ms; duplicate-charge bug caught before launch
ERP
Modular ERP covering inventory, procurement, accounting and HR with complex cross-module data flows.
Approach: end-to-end business scenarios, database-level verification and a modular regression suite per ERP module.
Result: 300+ automated business scenarios; cross-module data defects reduced by 50%
CRM
Sales and customer-management platform with leads, pipelines, reporting and third-party integrations.
Approach: workflow-based test design, data-driven tests for imports and reports, and integration contract checks.
Result: Report accuracy issues found before go-live; integration regressions caught in CI
E-commerce
Online store with catalog, cart, checkout, promotions, payments and order management.
Approach: revenue-critical paths automated first, with performance baselines tracked before each major release.
Result: Checkout held 2× peak campaign traffic with no errors; release cycle shortened by 30%
POS
Retail POS handling sales, returns, discounts, inventory sync and end-of-day reporting.
Approach: decision-table testing for pricing rules and data reconciliation for every financial report.
Result: Tax and discount calculation defects eliminated before store rollout
WordPress / CMS
Content-driven business websites built on WordPress with custom themes, plugins and forms.
Approach: launch checklists combining functional, visual, accessibility and performance checks with upgrade regression.
Result: 20+ sites launched with Lighthouse scores above 90 and zero critical accessibility issues
AI
AI-powered product where output quality, consistency and the surrounding application must all be verified.
Approach: curated input datasets, expected-behaviour criteria for non-deterministic output, and automated API regression.
Result: Output-consistency regressions detected automatically on every model update
QA automation framework
The architecture I use to keep large UI and API suites fast, readable and stable in CI.
Readable, behaviour-focused tests grouped by feature and tagged by risk (smoke, regression, critical).
UI interactions and API calls encapsulated once, so a UI change is a one-file fix.
Isolated, API-seeded test data and authenticated sessions for independent, parallel tests.
Playwright runner with environment profiles, retries for flaky infrastructure, and cross-browser projects.
Runs on every pull request with HTML reports, traces, screenshots and failure triage.
import { test, expect } from '../fixtures';
test.describe('Checkout @critical', () => {
test('customer can pay with a saved card', async ({ api, checkoutPage }) => {
// Arrange: seed state through the API, not the UI
const cart = await api.createCart({ items: ['SKU-1001'] });
// Act
await checkoutPage.open(cart.id);
await checkoutPage.payWithSavedCard();
// Assert: UI and backend agree
await expect(checkoutPage.confirmation).toBeVisible();
const order = await api.getOrder(cart.id);
expect(order.status).toBe('PAID');
});
});Open-source QA work
Client work stays confidential, so these public repositories show the same practices end to end — each one runs in CI and publishes its test report.
github.com/your-username/playwright-framework
Layered UI + API framework with page objects, API-seeded fixtures, cross-browser projects and sharded runs on GitHub Actions.
github.com/your-username/api-test-suite
Contract, negative and authorisation tests against a public API, with JSON Schema validation and Newman reports in CI.
github.com/your-username/k6-performance
Load, stress and soak scenarios with thresholds as pass/fail gates, environment profiles and HTML summary reports.
github.com/your-username/portfolio
The site you're reading is tested like a product: Playwright E2E, axe accessibility checks and Lighthouse CI budgets on every push.

Testimonials
Feedback from engineering managers, developers and product owners I've shipped with.
Abdulla's Playwright suite and risk-based test plans changed how we release. Regression went from a multi-day manual effort to an automated run on every pull request, and we now ship with real confidence.
His bug reports are the best I've worked with — clear steps, logs and expected results every time. He caught critical API and data issues long before they could reach production.
Before our biggest launch, Abdulla ran load and performance tests that exposed a bottleneck we would have missed. The release went live smoothly and the system handled peak traffic.
