Hi πŸ‘‹, I'm Piyush Lahoti

Software Engineer | Backend & Distributed Systems | Building Systems That Scale

Typing SVG


πŸš€ About Me

  • ☁️ Currently working as Software Engineer III @ eBay, on eBay Cloud β€” managing cloud security and building new features using Kubernetes and Go
  • 🏦 Previously at JPMorgan Chase, building reconciliation systems that process millions of transactions daily
  • πŸ”­ Before that, at Gupshup Technology, where I architected event-driven systems processing 50M+ daily events and cut messaging latency by 60%
  • πŸ’‘ I care about system design, reliability, and performance β€” turning "it works" into "it works at scale"
  • πŸ“š I write and maintain resources on LLD and HLD to help others (and myself) get better at system design
  • 🎯 Actively exploring backend/infra roles at product-based companies
  • ⚑ Fun fact: I've cut deployment time by 85%, latency by 60%, and infra cost by ~20% β€” I like making systems faster and cheaper at the same time
