💼 Experience: 7+ years (3.5 years in production environment)

Professional Summary

I’m a backend software engineer with over 7 years of experience in software development, including 3.5 years of real-world experience in production-grade systems at companies. My core specialization lies in Golang and PHP, focusing on building scalable, efficient, and maintainable backend systems. I’ve worked extensively with Kafka, REST APIs, and large-scale databases handling millions of records monthly. I’m comfortable working in environments powered by Docker, Kubernetes, and CI/CD pipelines using GitHub Actions or Jenkins.

Key technical strengths:
- Performance and memory optimization
- Asynchronous processing (workers and message queues)
- Feature flagging and gradual deployment
- Observability and APM (logging, tracing, profiling)

I believe that great engineering solves real-world problems and drives real impact. I enjoy iterating on system design, debugging complex cases, and delivering robust solutions that scale in production.

PT Majoo Teknologi Indonesia | Remote

Backend Senior Associate – Core Backend Engineering Team

As part of the Core Backend Engineering Team, I was responsible for the development and maintenance of key business modules, including Transactions, Inventory, Products, and Accounting. My role was focused on three main areas:
🛠 Feature Development
- Designed and implemented backend features using Golang, following clean architecture principles and REST API standards.
- Collaborated closely with Frontend engineers, QA testers, and Product teams to deliver reliable and user-aligned functionality.
🐞 Bug Fixing & Maintenance
- Handled production bugs and issues by performing log analysis, tracing, and root cause investigation.
- Optimized complex SQL queries and batch processes managing millions of records.
- Utilized Kafka, MySQL, and various observability tools for stability and monitoring.
🌱 System Improvement
- Refactored legacy modules to improve code quality, performance, and maintainability.
- Improved memory efficiency in high-load processes—e.g., using stream-based Excel generation to export large reports without loading all data into memory.
- Reduced execution time of intensive operations to under 5 seconds.
- Implemented feature flagging using GoFeatureFlag to manage rollout strategies.
CI/CD pipelines were managed using Jenkins, with containerized deployment via Docker and Kubernetes. Production environments were monitored using Elastic APM, Grafana, etc.

PT GITS Indonesia | Remote | Internship

Back End Developer Golang (MSIB)

As part of a structured backend training program at GITS Indonesia, I focused on learning and applying Golang for web development. The program culminated in a capstone project titled "Dorplas", a web application developed using Go (Golang) and PostgreSQL.
📌 Key Responsibilities:
- Built backend API endpoints using Golang, implementing basic CRUD and relational logic.
- Managed PostgreSQL integration and schema design.
- Handled deployment and environment configuration using Heroku, including build pipeline and config variables.
- Gained hands-on experience in version control (Git), RESTful API design, and collaborative development.
This experience gave me a strong foundation in Golang-based web development, including both programming and deployment aspects.
