About

Professional summary

I am an AI/ML engineer and data scientist with more than six years of experience building machine learning, data, and full-stack software solutions. I work across the complete lifecycle, from data engineering and model development through deployment, monitoring, and ongoing improvement.

I specialize in LLM and RAG applications, computer vision, MLOps, and financial software. My work includes automated model retraining, experiment tracking, model versioning, real-time observability, anomaly detection, and production serving.

I build practical AI systems using Python and modern ML frameworks, including solutions for document intelligence, multi-agent retrieval workflows, stock-signal modeling, and object detection. I focus on traceability, evaluation, reliability, and measurable model performance.

I also develop full-stack applications and financial management systems with robust accounting workflows, audit logging, role-based access, reporting, and automated operational processes. I am comfortable deploying on-premise and containerized applications.

Most of my client engagements are confidential, but my public GitHub projects demonstrate the architectures and engineering practices I use in production. I also contribute to open-source projects, including Indonesian job-board providers for the career-ops platform.

I am available immediately for remote or hybrid full-time, contract, and freelance roles in ML engineering, data science, MLOps, and full-stack development.

Career history

Data Scientist & ML Engineer (Freelance) Independent Consultant

I deliver data, machine learning, and software projects for enterprise and public-sector clients, taking engagements from discovery and scoping through deployment, monitoring, and maintenance. Most client work is confidential, with representative architectures available through public GitHub projects or on request.

I have built automated ML retraining pipelines, real-time monitoring and alerting systems, and multi-stage computer vision pipelines that improved accuracy over single-stage baselines. I manage the end-to-end MLOps lifecycle, including experiment tracking, model versioning, serving, observability, and anomaly detection. I have also delivered financial management systems with double-entry accounting, audit logging, and automated operational workflows.

Data Analyst Confidential Clients (Public Sector)

I analyzed digital media performance across multiple platforms for public-sector communications teams. I performed exploratory data analysis to identify engagement trends and insights that informed campaign strategy.

I built dashboards and reports designed for non-technical decision-makers. These reporting tools helped stakeholders understand engagement data and take action based on measurable communication performance.

Data Engineer Intern Star Energy

I supported a migration from legacy file systems to SharePoint during a data engineering internship. My work included assisting with the movement and organization of existing data assets.

I contributed to metadata standardization and data consistency checks to improve the quality and usability of migrated records. This work supported a more structured and reliable document-management environment.
