Mahzaib Sher

I’m a Software Quality Assurance Engineer focused on ensuring secure, scalable, and high-quality decentralized applications. I bring expertise in blockchain and DeFi ecosystems, with hands-on testing experience across Solana and Celo, plus finance and trading platforms.

In my recent work, I perform functional and non-functional testing to ensure reliability and performance, and I validate finance-related workflows for data accuracy and compliance standards. I also test and optimize AI chatbot solutions to improve accuracy, usability, and seamless user interactions.

Previously, I tested Solana-based applications for reward timing, deposit/withdrawal integrity, and performance under stress. I also validated wallet and Discord integrations, one-to-one linking, accurate task reward distribution, referral functionality, and UI compliance against Figma designs.

I’m comfortable owning detailed test cases across the SDLC, collaborating with cross-functional teams to resolve issues, and improving QA processes for efficiency and timely delivery. I mentor junior team members, follow STLC and Agile practices, and use tools like Jira, Postman, and JMeter to support strong release quality.
