CashFlow AI - Smart expense tracker

My second personal product, built using React Native and Python Django, allows users to track their expenses effortlessly without filling out numerous forms. Simply type your multiple income or expenses in a sentence or paragraph, for example, "spent $20 on gas, $100 on tuition fees, earned $500 from freelancing," and the app will automatically create three separate entries for you: two expenses and one income. It's that simple. Read the dedicated blog post here.

Jobcase

Jobcase is a leading platform for blue-collar workers. Jobcase acquired upward.net, raised over $80 million and became the third-largest online jobs portal. I've developed multiple new features for Jobcase as Sr. Software Engineer at Arbisoft.

• Led a team of seven engineers to exceed client expectations and deliver high-quality results in each sprint.

• Led end-to-end implementation and improved performance from 20fps to 50+fps

• Upgraded React Native from 0.64 to 0.68, resolving several breaking changes

• Improved app speed through effective use of memoization.

• Implemented a user-connection feature

• Streamlined QA with the integration of Detox end-to-end testing and GitLab pipelines using custom runner

Technologies Used: Javascript, React Native, Redux, Detox, Jest, Launch Darkly, CI/CD, Fastlane, Adjust SDK

The Bitcoin Company

• Developed TheBitcoinCompany's app, a simple, private, and easy-to-use platform for earning, learning, spending and saving Bitcoin

• Wrote test cases to ensure reliable public releases in beta version

• Got this freelance project from a previous client(Sifir.io) to convert mockups to responsive design, integrate APIs, and configure end-to-end testing with Detox

Technologies Used: Javascript, React Native, Redux, React Query, Detox, Fastlane, Stripe

Sifir.io

• Designed and coded a visually stunning, user-friendly Bitcoin open-source wallet (Sifir.io) in React Native

• Optimized animations for fast performance and minimized JS overload

• Provided customization options for privacy and anonymity

• Rethought UX for optimal mobile use and accessibility for all users

Here's how it looks!
