About Me

Hey, I’m R S Devi Prasad! 👋

I am a Senior Software Engineer specializing in Distributed Systems, Data Foundations, and High-Performance Infrastructure. Currently, I build scalable data orchestration pipelines and AI infrastructure at Walmart.

My engineering philosophy centers around system efficiency, JVM tuning, database optimization, and automating complex asynchronous workflows to drive tangible business metrics. I started this blog as a technical notebook to document complex engineering challenges, architectural deep-dives, and performance optimizations.

🛠️ Core Stack & Expertise

  • Languages: Java (Expert – Concurrency, JVM Tuning), Scala, Python, Go, SQL
  • Data & Distributed Systems: Apache Spark, Apache Beam, Kafka (Reactive)
  • Databases & Storage: BigQuery, MongoDB, Redis (Advanced Caching), PostgreSQL, Elasticsearch
  • Cloud & Infrastructure: GCP, AWS, Docker, Kubernetes, Grafana, Jenkins
  • AI Orchestration: LangGraph (Agentic Workflows), Model Context Protocol (MCP)

🚀 High-Impact Wins

Here is a look at some of the scale and infrastructure challenges I’ve tackled throughout my career:

⚡ Scala & Spark Migration (Walmart)

Re-architected a legacy Java microservice to Scala/Spark, slashing pipeline execution runtime from 6 hours to 10 minutes (a 97% latency reduction) and cutting compute costs by 80%.

📉 Infrastructure Optimization (PharmEasy)

Engineered MongoDB and Redis data structures to achieve a 50% data footprint reduction and scaled throughput 4x using Reactive Kafka.

🔄 Asynchronous Orchestration

Spearheaded zero-human-intervention automation for an end-to-end page pipeline, integrating 6 distinct asynchronous services to hit a 500k scale in 6 months.
