About Me

About Me picture

Hello World! 👋 My name is Prateek Bansal. I am a software engineer with 4+ years of experience building scalable distributed systems and high-performance microservices. Currently, I am working at Payoneer as an L4 Software Engineer. People here love me and calls me a Revamp boy 😎.

I consider myself an artist who builds products using creativity and of course "JavaScript". From slashing API response times by 96% to building systems adopted by ~75% of clients, I love solving crazy engineering problems that impact people's lives. Finding elegant solutions to complex backend challenges is what makes me happy and satisfied.

Fun-Fact — I love JavaScript, Jalebi and Jethalal 😄
