Abhishek Kharche

Computer Science graduate, interested in solving complex problems by building scalable and efficient solutions. At PayPal, I worked on some cool projects like improving latency for checkout flows, scaling a large database from handling 700 payments/second to 10,000 payments/second by database sharding and migrating monolithic core payment fulfillment services to micro service architecture. Currently, I am focussed on building a Geolocalized payment processing so that PayPal could be compliant and offer its services in all parts of the world.
