2+ years building backend microservices and ETL workflows — from Java Spring Boot APIs to SSIS pipelines in the insurance sector. Strong software foundation applied to reliable data systems.
I'm a Software Engineer with 2+ years bridging backend development and data pipeline work. Currently at PT. Asuransi BRILife, I design and maintain SSIS-based ETL workflows for insurance transaction data while also building and maintaining microservices for the MoKlaim claims platform.
Before that, I built backend HRIS systems and payroll modules at PT. Lawencon International using Spring Boot, PostgreSQL, and Angular — and completed an intensive Data Engineering bootcamp covering ETL pipelines, data warehousing, and SQL-based transformation.
I'm equally comfortable writing a stored procedure and scaffolding a REST API. I hold an AWS Cloud Practitioner certification (in progress) and am deepening my modern data stack skills.
Maintained and enhanced a legacy claims application built in PHP CodeIgniter, then led the re-architecture to Java Spring Boot and Python microservices. Also maintains the ETL pipelines and data-serving APIs used across multiple business units at BRILife.
Built core payroll and HR backend modules consumed by multiple microservices using Spring Boot and Java. Developed responsive Angular 16 interfaces and supported payroll, time, and attendance features for large enterprise clients.
Built backend APIs with Spring Boot and PostgreSQL in a microservices architecture, enabling organizations to manage and track physical assets with full audit trail and reporting capabilities.
Implemented an indoor positioning system using Bluetooth Low Energy (BLE) and ESP32 microcontrollers. Built a real-time JavaScript interface to track people's positions indoors — an early foray into IoT and embedded systems.
Designs and maintains SSIS ETL workflows to extract, transform, and load insurance transaction data into SQL Server for reporting and analytics. Builds and maintains microservices and REST APIs for the MoKlaim claims platform (Spring Boot, Python, PHP CodeIgniter, PostgreSQL). Containerizes and deploys services with Docker and Kubernetes, and optimizes CI/CD pipelines for improved reliability and faster deployments.
Developed backend microservices and REST APIs for enterprise HRIS platforms using Spring Boot and PostgreSQL. Built Angular frontend modules for end-to-end HR workflows. Implemented automated report generation with Apache POI and Jasper Reports. Also completed an intensive internal Data Engineering bootcamp covering ETL, data warehousing, and SQL-based transformation.
Supported maintenance of Single Lane Free Flow (SLFF) tolling systems and assisted in deploying Automatic Vehicle Counting (AVC) systems. Researched and tested STM32-based embedded systems for Electronic Toll Collection (ETC) and helped integrate IoT solutions into large-scale transportation infrastructure.
Open to Software Engineering, Data Engineering, or hybrid roles. Happy to chat about microservices, ETL pipelines, or the modern data stack.
