The app has an indexer service & REST API written in Typescript/NodeJs and a React front end.

* Worked closely with engineers and managers to conceptualize, architect, build, maintain and improve full-stack web and mobile applications and back-end services in accordance to best practices.* Mentored junior team members.* Proficiently addressed time-sensitive technical incidents in the production environment.* Conducted code reviews.Highlights:* Built and maintained an internal full-stack web application for monitoring and processing cryptocurrency payments across multiple crypto payment providers. The app had a Javascript back-end and a simple EJS frontend.* Built and maintained a suite of microservices for processing cryptocurrency transactions on multiple networks (Bitcoin, Ethereum, Ripple, Stellar, Tron). All services were written in Javascript.** Reduced Bitcoin transaction fees by leveraging the number of inputs & outputs of a transaction.** Improved user experience for Ethereum withdrawals by implementing transaction resubmit mechanism to avoid stuck ETH transactions from a single account.

Designed and implemented a back-end in PHP with Laravel for a custom content management system for companies in various industries.
