drevelopment

• Built an internal e-commerce operations portal that gives the team a single interface to manage product listings and track orders across e-commerce storefronts, eliminating the need to switch between platforms manually. • Designed the system to consolidate multi-channel order fulfillment into one unified view, reducing operational overhead and the risk of missed or duplicated orders across sales channels. • Delivered the portal as a fully production-ready system with secure VPS hosting, SSL encryption, and scalable frontend deployment which was built to support the team's long-term growth without requiring infrastructure changes

•​ Build and ship SuperMap-based and ESRI-based GIS applications end-to-end for retail and government clients, translating user needs into reliable, map-driven products. •​ Develop a geospatial portal for a government intelligence agency, integrating spatial data from heterogeneous sources including Esri ArcMap and Eternix Blaze Terra into a unified platform featuring a project and data catalog, daily data gallery for weekly picket schedules, and quick-access hub for ArcGIS and Blaze Terra tools with revenue of 300 million rupiah. •​ Develop location-intelligence solutions that turn geospatial data into decisions (site selection, coverage analysis, regional insights). •​ Create AI-powered image recognition workflows for plant-health monitoring to detect anomalies and inform agriculture operations. •​ Deliver mobile logistics tools for on-premise vehicle navigation and fleet efficiency within private facilities. •​ Engineer ETL pipelines that migrate/transform multi-source datasets into the SuperMap ecosystem for high-performance visualization and analysis. •​ Implement Python snapping-detection algorithms to analyze pipeline networks and distinguish multi-branch connections for accurate mapping. •​ Own end-to-end maintenance for government GIS apps: triage and fix defects, handle license expansions, prioritize codebase remediation, write clear technical docs, and lead internal knowledge-sharing to upskill the team with revenue of 750 million rupiah. •​ Develop a domain-specific LLM tailored for GIS applications to support spatial analysis and insight generation.

•​ Extended Blibli's in-app financial investment feature, enabling millions of active users to invest in digital gold and reksa dana directly within the Blibli iOS app that deepened the platform's role beyond e-commerce into everyday personal finance. •​ Researched and developed an internal CoreML-powered tool to automatically detect and remove duplicate and unused image assets across the codebase, reducing app bloat and improving the development team's asset management workflow.

• Developed an internal portal website utilizing the Typescript programming language. • Addressed and resolved any bugs that may arise in the portal website. • Conducted code refactoring to enhance the efficiency and maintainability of the existing codebase.

• Guided undergraduate students through foundational programming concepts in C and object-oriented design principles through Framework Layer Architecture (FLA) in Java language, helping build their core engineering mindset. • Designed examination cases for SQL and Data Structure modules, and evaluated student submissions for the FLA course directly contributing to the academic assessment quality for 30+ student
