### Summary
Hello! Iām an electronics and computer enthusiast with a passion for exploring the world of technology. My interests revolve around various areas such as **[electronics](https://www.instagram.com/arduino_craft/)**, **[video editing](https://youtube.com/gabrielkheisa)**, web and **[cloud development](https://www.cloudskillsboost.google/public_profiles/5aebc257-069e-4ea3-8aa8-289d903f8a35)**. I find joy in simplifying tasks and processes using cloud infrastructure and AI technologies. When Iām not immersed in the digital realm, you can often find me indulging in video games, which are a great source of entertainment and relaxation for me.
As an avid learner, Iāve delved into the realm of IoT and microcontrollers. I particularly enjoy creating Arduino or microcontroller-powered devices that connect to my server. Speaking of servers, I have my very own [**home server**](https://www.nslookup.io/domains/meme.gabrielkheisa.xyz/dns-records/), repurposed from an old Intel Celeron laptop. Prior to embracing cloud computing, I utilized this server as an IoT and API gateway for my microcontrollers.
In terms of achievements, I was a finalist in the [**EU Digital Marathon**](https://gabrielkheisa.xyz/img/sertifikat_digithon.jpg), specifically for my efforts in combating cyberbullying as part of the Nagantaka team. Additionally, I had the privilege of being the 1st winner in the UAV team as a hardware programmer in the [**National Flying Robot Contest**](https://dcse.fmipa.ugm.ac.id/site/id/gamaforce-juara-umum-pada-kontes-robot-terbang-indonesia-krti-2021/). With two years of experience in flight controller programming and computer vision, I contributed to the success of the GAMAFORCE team.
Another notable accomplishment was winning the **[Farmasi Innovative Academy UGM](https://www.bulaksumurugm.com/2021/12/02/farmasi-hadirkan-kompetisi-inovatif-dengan-kolaborasi-3-universitas/)**, where I developed software for medicatia.co. This experience allowed me to showcase my skills as a software developer. Moreover, I am a [**2022 Bangkit Graduate in the Cloud Computing Learning Path**](https://gabrielkheisa.xyz/img/graduate.jpg), achieving the [**distinction**](https://gabrielkheisa.xyz/img/graduate.jpg) of being selected as part of [**The Best Team**](https://gabrielkheisa.xyz/img/capstone.jpg) in the Bangkit Company Capstone Project. My journey in Bangkit equipped me with a strong foundation in cloud infrastructure, encompassing essential services like compute (e.g., virtual machines, serverless functions), storage (e.g., object storage, block storage), databases (e.g., relational, NoSQL), and networking (e.g., virtual private networks, load balancers). I also gained expertise in CI/CD practices, particularly leveraging Github Actions and Jenkins for automated builds, testing, and deployments. Furthermore, I honed my skills in cloud automation using Ansible and Terraforms, enabling the efficient provisioning and management of cloud resources.
I leverage my expertise as a full-stack developer and [**cloud engineer**](https://www.linkedin.com/in/gabrielkheisa/), tackling challenging projects and contributing to the development of robust cloud-based solutions. Previously, I served as a [**Cloud Computing Mentor**](https://gabrielkheisa.xyz/img/sertifikat_mentor_bangkit.jpg) from July 2023, where I remotely assisted mentees with capstone and product-based projects, providing guidance on cloud deployments, machine learning integration, and mobile development.
To enhance my knowledge and skills, I have obtained certifications in cloud engineering and architecting from platforms like [**Coursera**](https://www.coursera.org/account/accomplishments/specialization/certificate/YDPV66P8WJCP) and **[Dicoding](https://www.dicoding.com/certificates/81P2G6Y2NPOY)**. Additionally, I have achieved the Python PCAP certification to strengthen my programming skills.
I am constantly driven by curiosity and the desire to explore new frontiers in technology. With my diverse background and experiences, I strive to make meaningful contributions in the ever-evolving world of electronics, computing, and cloud technology.
