E-dash is a Japanese company established by Mitsui & Co., Ltd., focusing on supporting corporate and municipal initiatives to reduce CO2 emissions through a comprehensive digital platform. The primary product they offer is the “e-dash” service platform, which helps visualize, calculate, and manage CO2 emissions.As a Full-stack Developer, I am responsible for developing new features and fixing bugs for the “e-dash” service platform. My role involves working on both the front-end and back-end components of the platform, ensuring its functionality, usability, and performance meet the needs of our users.

Traffic Sim is a company that provides various services and hardware for broadcasting companies. I have worked in various projects:1. Electric Current Monitoring Service- Worked as one of the main Full-Stack Developer and implemented the frontend as well as backend components that receives and displays electric current data, which then can be used to detect anomalies and potentially reduce electric usage cost.- Worked with 8 other people including 2 software developers from Vietnam.- Deployed the system on AWS cloud using Terraform and ECS.- We use Go for the back end for better performance and Next.js for the front end for better react project management.- Applied software development best practices (e.g. Clean Architecture, CI/CD, Atomic Design) to improve code maintainability.2. Stream Monitoring Service- Devices will send the stream to the server and it can be watched through a web application with small latency.- Worked with 2 other people as a full-stack developer that mainly handles the front end and non-stream-related back end.- Because of my work, the User Experience and how the web app feels when operating it became better and smoother.- We used AWS for the deployment.- We used Node.js configured for TypeScript for the back end and Vue.js for the front end as we deemed that Single Page Application should be enough for the web application that we’re trying to make because we don’t need to make it open to the public.

I was working on a project with Pertamina RTC (Research and Technology Center). The goal of the project is the update of the software that can predict well performance with various enhanced oil recovery methods. The software can also be used to optimize production and is integrated with energy economics to predict whether it is profitable to use certain methods or not. Unique to this iteration is the application of Neural Network as the previous one only used regression in their calculation. my part is the Chemical Injection Huff and Puff Method. I create and plan the engineering side while communicating with a dedicated programmer so that the physics matched with the calculation and matched with the software.

I was researching the application of machine learning in the Oil and Gas industry. This leads to the goal of submitting one paper to the Technological Journal of Ikatan Ahli Teknik Perminyakan Indonesia (Indonesia's Petroleum Engineer Association). I lead a team of 3 people for this task.

I was tasked to monitor producing wells and to create programs for troubled producing wells. I was also sent offshore to watched over the workover process for one week.

Conducting well log data analysis on 5 fields (Belimbing, Jirak, Rantau, Sago, Talang Jimar) to be considered as references for future Plan of Development. I'm also conducting a literature study on waterflood optimization software.
