Predicting Traffic in Guangzhou, China

Associated with MSc. Data Science, University of Helsinki

Data Scientist & Data Engineer • Python • Jan 2022 — May 2022

The delivery product is a model that gives good enough accuracy with less cost, including the run time of the model's training. This project consists of four people. My responsibilities were

• Explored the causes of traffic from variables that were given
• Tried several models that could give good enough accuracy
• Created a data pipeline on Amazon Web Service
• Monitored and analyzed computing costs between models

News Topic Classification

Associated with MSc. Data Science, University of Helsinki

Data Engineer • PyTorch • Feb 2022 — Apr 2022

This project's purpose is to classify multi-label news topics on each document. Each document is in XML format. This project consists of three people. My responsibilities were

• Created a pipeline to process the classification on CSC's High-Performance Computing (HPC)
• Monitored and analyzed computing costs on CSC's HPC

Analyzing Annual Performance Evaluation

Associated with National Public Procurement Agency of Indonesia

Data Analyst • R Language • Dec 2021 — Jan 2022

This project aims to measure employee performance. NPPA has three types of employees, namely individual consultants, consulting firms, and other services. With an annual performance evaluation that is analyzed in-depth like this, upper management can gain insight to determine what actions need to be taken to manage employees in the future. This project was purely my own initiative without any orders from others because I saw that there was no good scoring and evaluation system at that time. These assessment parameters will be continuously updated according to the work environment.

Predicting New Particle Formation (NPF) in Forest

Associated with MSc. Data Science, University of Helsinki

Data Scientist • R Language • Oct 2021 — Dec 2021

This project aims to figuring out when the NPF Events occur and classifying the NPF events. This project consists of two people and use R language. My responsibilities were finding the correlation between variables, tried the dimension reduction, tested classifiers, and estimated classifiers. The methods that are used were

• Created a correlation between variables
• Analyzed correlation between all datasets (mean and std.)
• Used Principal Component Analysis for the dimension reduction due to the nature of how it derives its factors
• Tested classifiers using discriminative (Support Vector Machine) and generative (Naive Bayes)
• Estimated the performance of the classifiers using two metrics":" Accuracy and perplexity
• Made the estimates more generalizable to the test set using k-fold cross validation

Predicting Graffiti Using City Layout

Associated with MSc. Data Science, University of Helsinki

Data Analyst • Python • Sep 2021 — Oct 2021

This project analyzes what city properties correlate with graffiti generation in Vancouver, CA. This project consists of three people. My responsibility in this project was to explore the relationship and correlation between variables so that we could focus on the causes of graffiti further.

SIKaP

Associated with National Public Procurement Agency of Indonesia

Product Manager • - • Jan 2019 — Dec 2021

Sistem Informasi Kinerja Penyedia (SIKaP) is a vendor managemet system. I led releasing two major versions of SIKaP, 2.0 and 3.0. Some major features are vendor registration, vendor and buyer assessment, public search for vendors, transparency of change history and data verification, and integration data with several ministries, such as the Ministry of Finance, Investment Coordinating Board, and Ministry of Public Works and Public Housing.

This project is the most challenging for me. Why challenging? Because there were many things to be done in technical and non-technical aspects. For example, vendor registration features.

Uniform User Experience

Product Manager • - • Jan 2019 — Dec 2021

This project aims to make it easier for users to use the system created by the NPPA. In addition, in this project, I also focused on making the system friendly to people with disabilities. I started this project because I noticed difficulties for users when using some of the existing systems with different experiences. Meanwhile, unifying all these systems is very difficult because several systems have different requirements, and the complexity is quite difficult. Therefore, this project needs to be implemented in every system so that the system can implement the experience offered by this project.

Inaproc

Associated with National Public Procurement Agency of Indonesia

Product Manager • - • Mar 2018 — Sep 2018

Inaproc is a system that contains all the contents of Indonesia's goods/services procurement. Apart from that, one of its major features is to impose sanctions on vendors by blacklisting them. I led a team of systems analysts, programmers, and technical writers. The challenge for this product is implementing standard regulations into applications. The next challenge is to make a product that is easy to use. If the user has difficulty, it is feared that the user will make an error in displaying this black list.

Moreover, the users who broadcast this black list are officials whose positions are already very high in their respective agencies. Consequently, an error in the blacklist may prevent the vendor from participating in government procurement throughout Indonesia, and legal action may be taken against the user.

The solution offered is to match a user-friendly display for these officials. High-ranking officials owned one of the social media that I knew at that time was Facebook. So, I adopted a look and experience similar to Facebook. The following solution is to communicate with users to get a system that suits their needs.
