Background

About Darius Cupsa

I'm a senior fullstack software engineer with over a decade of experience building scalable systems across multiple programming languages and platforms. Since 2019, I've been working as a freelancer with an emerging ai company where I completely rewrote their initial MVP and scaled it to handle thousands of concurrent chats. I've architected most of their current system and led the technical transformation from intent-based support bots to LLM AI agents, while growing and mentoring a team of developers around me. My technical expertise spans TypeScript, GoLang, JavaScript, and Elixir, with deep experience in system architecture design, DevOps, AWS, GCP and OVH. Throughout my career, I've worked on diverse projects ranging from crypto trading exchanges and blockchain implementations to e-learning platforms and healthcare systems. I'm particularly skilled at taking projects from concept to production-ready solutions, whether it's building a sophisticated crypto trading platform like ParamountDax or developing real-time collaboration tools for global companies. I thrive in fast-paced environments and have extensive experience with Agile methodologies. My approach combines strong analytical skills with practical implementation - I believe in building robust, scalable solutions that solve real business problems. In my spare time, I'm an active open-source contributor and enjoy tinkering with IoT projects using Arduino and Raspberry Pi.
