# Harsh Golchha Jain on Tal

## Headline

Software Developer at InMobi \| Building high\-throughput backend systems \(2K\+ QPS\) \| Java, Spring Boot, Distributed Systems \| Codeforces Expert \| Leetcode Guardian \(Top 1%\)\| IIIT Lucknow ’25

## About

I build backend systems that handle thousands of requests per second and don't go down at 3 AM\. Currently a Software Developer at InMobi, where I designed and optimized a high\-throughput IAM service handling 2,000\+ QPS using Java 17 and Spring Boot 3 — reducing p99 latency by 35%\. I've built self\-service provisioning workflows that eliminated 70% of onboarding overhead, optimized data pipelines on Airflow cutting runtime by 12%, and set up monitoring infrastructure with Grafana and Prometheus that brought our MTTR from \~45 min down to \~15 min\. Previously interned at Cimpress, where I built ML\-integrated forecasting pipelines \(18% accuracy improvement\), designed near real\-time anomaly detection for financial data, and optimized SQL queries on 10M\+ row databases reducing latency by 80%\. On the competitive programming side: Codeforces Expert \(1642, top 0\.5% of 900K\+ users\) and LeetCode Knight \(1992, top 0\.3% globally\)\. 1500\+ problems solved across platforms\. B\.Tech in Computer Science from IIIT Lucknow \| 9\.04 GPA Tech I work with daily: Java, Spring Boot, Python, PostgreSQL, Docker, Kubernetes, AWS, Grafana, Prometheus, Airflow, Jenkins Always open to connecting with fellow engineers and discussing system design, backend architecture, or competitive programming\.
