Curious about me? Here you have it:

Greetings! | I'm a passionate, computer engineer who specializes in fields of full stack, network, data and machine engineering, mobile appilication development (Flutter, React-native & expo) and embedded systems. I am enthusiastic individual with a delve mix with curiousity. Reasearching, and working on the deep infastrature of the toolings i use and writing clear, readable, highly performant code matters to me.

I began my journey as a Computer engineer in 2020(previously a medicine university student), and since then, I've continued to grow and evolve as a well all round engineer, taking on new challenges and learning the latest technologies (mostly involved during the 'write it in rust phase') along the way. Now, in my early time entering twenties, 4 years after starting my journey in tech, I'm building and progressively producing cutting-edge applications (web, mobile or server infastrature) using modern technologies such as Next.js,TypeScript, SvelteKit (highly und strongly recommend) Tailwindcss, PostgreSQL and much more.

I am very much a progressive thinker and enjoy working on products end to end, from ideation all the way to development.

You can find me surfing around on youtube or trying to brain storm what i envisioned before picking up a career in tech, witnessing the journey of early startups or enjoying some free time. You can follow me on Twitter where I share tech-related bites and build in public (lies, i only use twitter for news and whats trending, hehe), or you can follow me on GitHub.

Finally, some quick bits about me.

  • B.Sc. Computer Engineering
  • Freelancer oder contractor
  • Avid learner
  • Aspiring indie hacker
  • I watch anime too but not like those you lurk in the shadows do (thriller, mystery, romance)
  • I play games too (lies, well its only valorant and genshin i played like a game)

One last thing, I'm available for freelance work, so feel free to reach out and say hello! I promise I don't bite 😉
