Backend developer / shipping systems that scale

Nikhil Parashar

Backend Developer

I build backend systems that stay fast under real traffic. My work spans streaming infrastructure, distributed services, cost optimization, and product features used at scale.

About

Clean engineering with measurable impact.

I currently work at Loco, where I focus on backend systems for scale, performance, and resilience. My recent work includes rebuilding a streaming transcoder pipeline, automating anti-censorship domain rotation, and executing a zero-downtime architecture migration.

Before that, I built core product systems across messaging, virtual currency, load testing, and e-commerce operations. I enjoy projects that combine systems thinking, product impact, and measurable performance gains.

What I optimize for

  • Latency that holds up under load
  • Systems that are observable and easy to operate
  • Product features tied to clear business outcomes

Experience

Work shaped by scale, reliability, and product depth.

SDE-2, Backend @ Loco

Noida, India

  • Rebuilt the HLS streaming transcoder from low-level primitives, bringing initial load time down from 6-12s to 2-6s and reducing end-to-end latency by 60%.
  • Added adaptive bitrate output from 360p to 1080p to improve stream quality across low-bandwidth Tier-2 and Tier-3 regions.
  • Built an automated anti-censorship domain rotation system using regional monitoring and Amplitude-driven config updates.
  • Executed a phased migration from active-active multi-region AWS to a single-region architecture with health-check gating and zero user-facing downtime.

SDE-1, Backend @ Loco

Remote

  • Reduced the daily cost of a high-traffic DynamoDB table from roughly $60/day to $0.40/day through indexing changes and cold-storage archival.
  • Built a Golang load-testing framework from scratch, deployed on Kubernetes with Helm to simulate realistic user behavior.
  • Designed and shipped the full virtual currency lifecycle, including redemption, expiration, and withdrawal flows.
  • Optimized backend APIs to achieve P99 latencies of 180ms for GET and 300ms for POST and PUT under high load.
  • Architected and built Loco DM end-to-end, covering real-time messaging, transaction flows, and notifications.
