Work Experience
Software Engineer
2023 - 2024
Okta
- Revamped the Go SDK from scratch to support various authentication flows for Okta.
- Implemented passwordless login options using email and phone number and revamped standard OAuth 2 authorization code flow.
- Implemented the 1st ever decentralized authentication mechanism using users' Ethereum keys via a wallet like Metamask. This empowered users to authenticate with their Ethereum keys through Okta, eliminating dependence on centralized mechanisms.

Software Engineer
2022 - 2023
Reddit, Inc.
- Set up Prometheus monitoring services for the ads serving team, helping them gain insights on metrics. Set up alerting and monitoring on top of those metrics, decreasing issue turnaround time by around 30% compared to a sentry-based alerting system.
- Prepared, discussed, and led a company-wide initiative to migrate from thrift to gRPC communication. Reduced latency by 5% across ads service on an average, better load balancing across all the pods due to client-side load balancing.
- Designed and led the integration test framework for the core ads services to increase the test coverage and discover bugs in the system. After the implementation, we were able to decrease the incidents by 10%.

Experience
Pay Later POC
https://github.com/ohmpatel1997/pay-laterPay Later is a POC application for leading fintech company Simpl (https://getsimpl.com/), enabling users to make immediate transactions with partnered merchants. Users can pay later (monthly) based on their billing. The idea behind this project was to model the architecture, designing the database models and microservices. The project was entirely built using Golang.
Decentralized Storage
https://github.com/ohmpatel1997/ipfs-ethereumA project that leverages an interplanetary file system to store files in a decentralized network and track and maintain the files' metadata on the Ethereum blockchain. It uses ganache and Go-Ethereum for development purposes.
Logs Analytics Using Elasticsearch
https://github.com/ohmpatel1997/logs-extraction-elasticsearchThe project extracts logs from a huge log file of 16 GBs in seconds. The purpose of the project is to develop a Command Line Interface (CLI) tool that extracts logs efficiently from log files within a given range. The logs are then fed into an elasticsearch cluster for faster and more efficient querying and management. Hot-cold node architecture is used for time-based indexes. The project was built using Golang and features out-of-the-box elements such as synchronization primitives, memory pools, goroutines, and channels.
Twitter Mock Application
https://github.com/ohmpatel1997/twitter-graphqlA Twitter-like back-end app built using Golang, MySQL, and GraphQL for querying. The app can log in/signup. A user can post a Twitter-like two-sentence text post, follow another user, and view their timeline. The app is deployed using Docker Compose into multiple containers of the GraphQL server and database server.
