About Me
QA Engineer with 5+ years architecting automated testing solutions that cut regression time and slash production bugs. I specialize in Python, Selenium, Appium, and Pytest to build comprehensive frameworks for web and mobile platforms.
What sets me apart is my proactive collaboration style—partnering with product and design teams during ideation to anticipate issues before they exist, and translating quality metrics into business impact. My background in Entrepreneurship sharpens my focus on efficiency gains that drive bottom-line results.
From monitoring production health with Apache Superset to engineering Metabase BI dashboards, I blend technical QA expertise with data-driven operations. Based in Dubai, I thrive on solving complex testing challenges that help teams ship faster with confidence.

Featured Projects
Odoo
I hopped in the back office of a rice wholesaler and replaced the tower of clipboards with one Odoo box. Now every 50 kg bag that rolls off the truck is scanned, weighed, and instantly booked; same click prints invoice, charges inventory account, and updates the web-store stock counter. The owner used to chase nightly Excel sheets—now he pours tea while the system reconciles itself before close of business.
Selenium on Investagrams
Selenium scripts quietly patrol the site after each deploy, replaying every path a real trader might take—log in, open a chart, place an order, switch dark mode, log out. When someone accidentally breaks a selector or a new build slows down the dashboard, the suite pings Slack before the coffee finishes dripping. The tests don't ship features, but they keep Sunday nights free of rollback panic.
Visa Tracker
Agencies juggling tourist and freelance visas needed a shared desk, so I gave them a SvelteKit + PocketBase CRM: each customer gets a card, every embassy PDF lives in one drag-and-drop pile, and a color badge tells the agent where things stand without opening e-mails. No more hunting through drives for passport scans or guessing which embassy replied—one search bar surfaces the whole story.
