Selected notes on software engineering contributions to enterprise systems, microservice infrastructure, and production platforms.
A dedicated hotel search path using AWS Lambda and MongoDB, synchronized from the SQL source through CDC.
Developed the AWS Lambda search endpoint and the Go worker in sync-to-mongo that processes Kafka events into MongoDB as part of a team.
Bank Mandiri's internal HRIS platform with a Laravel interface and employee services APIs integrated with SAP.
As a fullstack developer, I built the Laravel interface and APIs for Employee Personal Data Consent, Data Subject Requests, Integrity Pledge, Business Travel, Car Ownership Program (COP), SRP, and Exit Management, including SAP integration in the relevant workflows.
An internal purchasing system that brings purchase requests, approvals, orders, payment records, documents, and reporting together.
Contributed to SMOOT's serverless backend: request and approval APIs, order workflow, payment records, document handling, notifications, audit trail, search, vendor master, and reporting.
A hotel booking portal for travel agents and B2B users, bringing search, payment, and booking monitoring into one application.
As a Full Stack Developer focused on frontend, I built login and email 2FA, hotel search and detail views, room and rate selection, booking, booking history, and credit/deposit summaries through Laravel API integration. I also kept search parameters consistent across pages and connected checkout to the 2C2P, GMO, and WEX payment gateway integrations.
