Hi, I'm Arihant. I'm a Principal Software Engineer. I’ve built production ready web apps and websites using React, Typescript, JavaScript, Node.js, Next.js, Astro, Redis, TailwindCSS, Strapi, Keystatic. I am passionate about teaching, because I understand not everyone learns the same way.
I've been in the startup trenches for over 15 years, having experienced both the early stage crucible and the continuing support of successful projects. As a mentor, I volunteered and worked for an educational non-profit for 4 years. I've also been an instructor and emcee for a local Lindy Hop dance venue I started for the past 4 years. It's a secret life I live away from the computers, but I believe those experience has helped me as a mentor. Most importantly, I believe in supporting newcomers and underrepresented groups into tech field, because this is the way to make technologies better serve the whole world. As a developer, I've worked on technologies used by film icons like Brad Pitt, designed and developed online games that had millions of users, and built mission-critical health care systems. As a mentor, my strength is in the ability to explain domain knowledge in a way that is easy to grasp, through analogies and examples. I have hired and coached many early-career engineers and it's something that I particularly enjoyed. To me, software engineering is a tool that brings ideas to life, and my career focus has reflected that. While I love to learn and talk computer science theories with fellow programmers, my passion lies in building what delivers value for the end users, our community, and the world.
Expert in swift, objective-c, Xcode. Programming for iOS since 2008. Crashes, performance issues and weird bugs are welcome.
Young generalist engineer graduate from Icam de Nantes (France), I am fond of a lot of stuff. Most of them are linked to new technologies, IT, and software development. I am currently in charge of R&D at Startup Palace, a company providing lots of services to startups, where I actually do many different things (which is something I like!). For example, I am helping CTOs of different startups with various tech problems they encounter. I also recently defended my PhD thesis in Software Engineering. I care about Open Source, and I like when my code is simple and maintainable. I'm here to meet interesting people with interesting problems, and do my best to help them! (Note: in case you wonder, helping beginners *is* an interesting problem)
I want to share the experience which I've gained during the last 15 years of production software development, so more great engineers will be available on the job market.
