I’m a Backend Software Engineer with nearly 3 years of experience building scalable backend systems. At Merabo Labs Pvt. Ltd. (Dealshare), I’ve owned critical business systems and delivered end-to-end features across multi-city e-commerce workflows.

I built and scaled the end-to-end Lowest Price Guarantee (LPG) system handling 4K carts/day and 15K SKUs/day across 7 platforms, scaling up to 10K carts/day via horizontal infra expansion. I engineered a configurable wallet rule engine, a scalable SKU- and location-level pricing engine (grammage, ranking, fallback logic), and PDP recommendation/ranking flows with metadata and intelligent fallback strategies.

I also designed scheduled price reporting and an async, queue-driven location-aware crawling/validation pipeline with caching, retries, failure handling, and reconciliation to protect pricing accuracy. My ETL pipelines achieved 99%+ data reliability, and I optimized BigQuery datasets (80GB, 300M+ rows), reducing compute costs by 30%.

I’m a “reliable and high-performance” builder by habit—comfortable with distributed systems, REST APIs, microservices, and data-heavy production workloads. Beyond backend, I’ve worked on ML research (RF/SVM for insider threat detection) and optimized a Genetic Algorithm for 99.95% accuracy, plus I’ve been recognized as Star of the Month for delivering scalable Lowest Price Guarantee platforms.
