System Design: Forward Retry Mechanism In Distributed Architecture

varunshrivastava — Mon, 08 Dec 2025 22:33:50 +0000

A Forward Retry is a mechanism where a failed operation to an external service(s) is automatically attempted again after a certain delay. The primary purpose of this design is to handle transient network failure, temporary outages thereby improving the reliability of the system. I recently faced a similar situation at work where I had to […]

Building Semantic Search for E-commerce Using Product Embeddings and OpenSearch

varunshrivastava — Fri, 27 Sep 2024 12:54:08 +0000

Hey! So, I recently worked on this cool proof of concept (POC) where I tried to combine product embeddings with OpenSearch to enable a k-nearest neighbours (k-NN) search. Basically, I wanted to see if I could make searching through a product catalog smarter by using embeddings (which are essentially vector representations of the product information) […]

Setup Frontend Project Without Needing Backend Using Local Storage (Dependency Injection)

varunshrivastava — Sat, 18 Nov 2023 04:55:20 +0000

Frontend applications have evolved with frameworks like React, Angular, and Vue, allowing for complex logic and seamless user experiences. The entire DOM is now generated using JavaScript, giving developers more control. This article discusses a design pattern that decouples frontend development from the backend, allowing frontend code to run without relying on backend readiness or API responses.
