## Professional Summary

My entire career, I faced a lot of challenges, from which I have learned to become better. The easy route and the hard route lead to the same destination, but I think that the hard route is best, thus this is why I developed my skills.

- Highly adaptable: looking after challenging projects in the wild, working tirelessly on the final product.
- Tenacious: Improving along the way, adapting to the fullest in any moment. It doesn't matter the production is down, I will dig up the problem and fix it.
- Creative: I will come up with a creative way of fixing problems or improving the field I work in.
- Innovative: Picking up broken things, fixing them, and redesigning the way things are done whenever possible, so the creation process is better next time.
- Continuous Learning: Like CI/CD, I apply CL to my own brain. The technology can't await, so I must keep up with it. Rapidly learning and implementing new technologies, like LLMs and Generative AI, extending to LangChain, OpenAI APIs, and various LLM models, either open-source or (pre-)trained.
- Frictionless: Coding with teams keeps me awake, but serving as a self-sufficient "one-man-team" on critical projects? That makes me feel alive!
- Stack-Agnostic: Proficient in building scalable applications using Laravel, Next.js, Remix, Nuxt, you name it. Worked with pretty much many development stacks, so I can adapt easier and can provide a solution that fits best in any moment. I can glide seamlessly across multiple ways of tackling challenges.
- Cloud-Agnostic: In the same manner as being Stack-Agnostic, I am also Cloud-Agnostic. I worked with multiple cloud providers, from AWS, Azure and Google Cloud to Hetzner, DigitalOcean and Vultr, to name a few.
- Role-Agnostic: What do I have to do? Backend? Frontend? Dev(Sec)Ops? Project Management? I can adapt easily, as I said. Wearing many hats can look chaotic, but it is pretty simple for me. It also keeps me away from boredom.

## Key Achievements and Technologies

- Architectured, built and maintained large-scale applications with the help of AWS and Laravel.
- Built Chatbots and RAG applications for various industries: internal applications, Legal, Finances and Advertising, using tools like LangChain, LlamaIndex, vector databases and trained models.
- Self-taught myself by getting a hold of the best practices, technical articles, the best tools and the history of trial and error of others, as well as my own experience of facing challenges.
- Contributed to open-source projects: Laravel packages, Procedural Generation maps, SaaS & Self-hosted platforms. Whenever I had a problem, I would fix it in the public so that others could benefit from it too.
- Mastered the (hard) way of Kubernetes and containerization architecture at scale, with Azure, AWS and Kubernetes.
