## Work experience

Software Development Engineer 1 at Blinkit, Jun 2024 \- Present · 2 yrs 4 mos, Gurugram, Architected a multi\-tenant employee performance platform on a normalized PostgreSQL schema, supporting configurable review cycles, dynamic reviewer mapping, automatic expiry and fallback scoring, and multi\-criteria evaluations with tenant isolation\. Drove platform adoption as the input to store\-manager reviews and retention\-bonus eligibility, giving managers a data\-driven basis to identify and offboard underperformers and motivating ∼20% of evaluated workers to improve their ratings month\-over\-month\. Led event\-driven manpower automation using Kafka, enabling asynchronous roster generation and on\-demand slot creation, eliminating manual roster creation and slot\-scheduling effort across operations\. Own and operate a high\-availability distributed microservice powering workforce slot booking, adherence, and attendance workflows across ∼3000 dark stores for ∼1M gig workers; currently leading the migration of its attendance module to a new architecture with idempotent event\-processing workflows, normalized persistence models, and backward\-compatible schema changes, rolling out via store\-level flagged shadow writes for a safe, zero\-downtime cutover\. Resolved a production race condition in the GetOrCreateUserId flow causing duplicate \(tenant\_id, employee\_id\) mappings; fixed the root cause by moving user creation to the upstream Ops layer, safely backfilled and deduplicated historical entries using an is\_active flag, and enforced correctness with a partial unique index – eliminating duplicates without any data loss\. Designed a configurable hierarchical warning framework to automate policy enforcement, replacing manual policy enforcement with warning groups, designation\-specific threshold overrides, and escalation workflows across employee roles and tenants\.

Software Engineer Intern at Jio Platforms Limited \(JPL\), May 2023 \- Jul 2023 · 3 mos, Hyderabad, Built a real\-time PPE detection system using YOLO v8, training models to detect multiple equipment types at >95% accuracy\. Developed a Python desktop application for real\-time detection on a live camera feed using OpenCV and Tkinter\. Created a web\-based image upload\-and\-detection tool using HTML, Python, and JavaScript\.

## Education
