Yash Priyadarshi

About

Backend/distributed-systems engineer who built a Golang distributed key-value store on AWS using Multi-Paxos, WAL, and non-blocking gRPC replication (cutting write latency ~40%) and proactively addressed tricky failure modes like leader-election livelock. Also developed a Python/Kubernetes cost-optimization scaling engine deployed with Helm/Terraform, delivering ~$40K annual savings while sustaining 99.99% uptime, and drives contract-first API development (OpenAPI/Swagger) to speed frontend integration.

Key Strengths

• Designed distributed key-value store with Multi-Paxos and linearizability across a 3-node cluster
• Reduced write latency ~40% via non-blocking gRPC replication using Go channels
• Improved durability and crash recovery with WAL + automated log replay; nodes rejoin cluster without manual intervention
• Built Python-based Kubernetes cost-optimization/scaling engine delivering ~$40K annual infrastructure savings
• Maintained 99.99% uptime during peak traffic surges via Helm/Terraform standardization and HA practices
• Identified and mitigated leader-election livelock in Paxos using randomized backoff
• Created Go-based resilience testing to validate Pod Disruption Budgets and prevent availability regressions during maintenance
• Contract-driven API development using OpenAPI/Swagger Codegen; reduced frontend-backend integration time by ~60%
• Hardened production auth and validation (Auth.js + Zod/Pydantic); reduced runtime mismatches by ~95%
• Implemented PostgreSQL row-level security policies for multi-tenant isolation
