About Cosmin Harangus

I'm a Fullstack Senior Software Engineer that likes to code in Elixir and Go, writes clean code and doesn't back out of a technical challenge. On the frontend I have a lot of experience with ReactJS (since its initial release and it's precursor Flow) and TailwindCSS. Over the last 5-7 years I've been involved in creating the entire architecture of an European crypto exchange, built an open source matching engine in Go that can handle +200k trades/second, refactored an AI chatbot to allows it to scale with 0 database requests and <50ms latency for non third party requests, built a social network in Elixir with optimised uploads, group instant chat with online presence and complex feed features as well as advised several startups on how to build their products faster. Previously (since 2004 when I started working professionally) I used the latest open source tech to achieve the best results for my clients and was not afraid to learn new tech. I worked with PHP and Javascript (with Angular, Flow, React) for many years and continued with NodeJs, Go and Elixir. I am also proficient working with AWS/GCP, Docker and Kubernetes. Currently looking to be involved with companies that build high performance products using Elixir or Go, so I can have the biggest impact from the start.
