# Avinash Kumar on Tal

## Headline

Senior Software Engineer \| Python, React, Distributed Systems, System Design \| Data pipelines, ClickHouse, LLM/RAG \| 7\+ yrs building reliable data\-intensive systems

## About

I'm a backend engineer with 6\+ years building data\-intensive systems and the pipelines and APIs that keep them reliable at scale\. Today I own core data infrastructure at Cloudverse, a multi\-cloud FinOps platform\. I built the pipeline that ingests AWS Cost & Usage Report data from customer S3 buckets into ClickHouse — orchestrated with Airflow, autoscaled on Kubernetes with KEDA, and designed for exactly\-once processing so nothing is double\-counted or dropped\. I also built the Reserved Instance / Savings Plan recommendation engines that turn raw billing data into concrete savings for customers across AWS, Azure, and GCP, and tuned ClickHouse to serve analytics dashboards in under three seconds\. What I care about most is the unglamorous stuff that decides whether a system survives production: idempotency, retries, clean data models, and predictable behavior under load\. On the side, I built an end\-to\-end, LLM\-powered legal research platform that makes millions of Indian High Court judgments searchable — a schema\-constrained extraction pipeline over locally\-served models, semantic search with pgvector, and RAG chat with grounded, non\-hallucinating answers, all on local hardware with no cloud LLM dependency\. I'm strongest in Python \(including the internals — asyncio, the GIL, generators, context managers\), distributed job orchestration, and reliability\-focused system design\. 📫 avinash\.kumar2020@outlook\.com · GitHub: github\.com/a\-v\-i\-7
