From unit tests to performance evaluations, I've championed the importance of comprehensive testing, recognizing its pivotal role in crafting resilient, bug-free software. Beyond mere functionality, tests empower us to build applications that are not just robust, but also easily maintainable. Performance lover: I'm passionate about performance optimization.

1.5xp | Ruby enthusiast 🌱 | My heart project: @Youclub | My SaaS : @Musicast

New profile

🌱 1.5 years experience as a developer (Permanent, Entrepreneurship, Freelance) Depozen: Permanent contract, I was focused on notifications and API integrations. Youclub (activities/clubs search engine): Initiated by my frustration with inefficient Google searches for local clubs, I envisioned and developed a dedicated app using a Ruby GraphQL API and React Native client, with web views integrated into the Rails codebase. Challenges : finding an API to query for to seed my app. Ensure data integrity between models and graphQL types. Challenges were about improving performance of query . Still improves to make. Despite its potential, it was a commercial failure, leading me to flush the database and remove it from Heroku. I later redeployed it in its MVP state for demonstration purposes. Co-founded Musicast: A platform for music competition organizers. After my co-founder departed due to loss of faith in the project, I continued alone, securing early clients before coding the entire SaaS from scratch. This included features like user roles, workflows, AI capabilities, and a dynamic planning generator which I believe is my most complex work due to its customizable settings. I chose not to commercialize it as handling customer support, marketing, sales, product design, and coding alone was overwhelming, particularly in a niche market. This led me to resume my job search. Recently: Diving deeper into Ruby methods to better understand how it works under the hood. Last very interesting moment was re-coding the belongs_to method in Rails with TDD. Current Learning: Diving into Swift during my free time to expand my mobile development skills. (Stanford course) Interests: I have a thing for projects with a mobile component. I am keen on tackling larger-scale projects and deeper Rails functionalities, areas I haven’t explored in my personal projects. Improving performances is an area that I like too. I attend every Paris.rb and React Native Paris events. Career Aspirations: Looking for a collaborative team with structured processes, code reviews, and a senior mentor to further my growth.
