    I am a passionate Full Stack developer and DevOps engineer with over 5 years of experience in creation of robust software to solve real-world problems. 𝗪𝗵𝗮𝘁 𝘀𝗲𝘁𝘀 𝗺𝗲 𝗮𝗽𝗮𝗿𝘁 ▪ Optimized workflow for speed and efficiency: Over the years, I've honed my workflow to maximize productivity. I use Neovim, the fastest code editor, and thoroughly test critical components to prevent future issues. This enables me to produce a high volume of quality code swiftly. ▪ I communicate well to make sure all possible scenarios and use cases are clarified. ▪ Problem-solving mindset: I can translate real, complex problems into technical specifications and derive clear implementation steps from them. ▪ I design maintainable and scalable environments, architectures, frameworks, and APIs that other developers enjoy working with. ▪ I’ve seen a lot: I’ve spent days trying to figure out why my triangle isn’t rendering in Vulkan, why the neural networks I’ve implemented aren’t getting smarter, or why my TLS certificates aren’t being recognized. Every time, I come to a solution and learn from it. Thanks to my diverse experiences, I excel at debugging. ▪ Entrepreneurial thinking: Development alone is undoubtedly enjoyable. However, it’s an incomparable feeling when I use it to solve real people’s problems.
