Enterprise Software Solutions
Built From Real Operational Experience

Pre-commissioning massive telecom & CCTV safety networks for high-risk offshore oil & gas facilities under strict international specifications.

Conducted loop checks, system verification, and pre-commissioning for the Saudi Aramco project (Lamprell, Sharjah) in coordination with Singapore’s Exctel Engineering.

Geographically dispersed nickel mining operations required automated, high-precision real-time environmental monitoring displays.

Configured PI MQTT Brokers to pull live IoT environmental sensor data into core PI Systems, defining PI AF hierarchies and creating custom PI Vision dashboards.

Streaming high-frequency sensor telemetry from mining assets into machine learning servers caused high latency and data buffer overruns.

Designed proof-of-concept and deployed PI Business Analytics to stream real-time plant telemetry directly into Confluent Kafka queues for LLM training inputs.

Real-time machinery telemetry and plant process data from Siemens/ABB DCS was isolated inside active industrial sites in Kalimantan.

Conducted fresh installation of AVEVA/OSIsoft PI Systems, engineering Asset Framework asset trees and designing live operational dashboards inside PI Vision via OPC servers.

Field operators in remote drilling yards (Pertamina EP Cepu) had no active cellular signal to report safety incidents (HSE observations).

Engineered an offline-first React Native HSE logging mobile application utilizing local SQLite database queues and automatic REST API sync.

High transactional database deadlocks and slow indexing under peak operations caused system-wide timeouts and ERP lag.

Developed customized low-overhead SQL Server query profiling scripts and automated deadlock monitoring alerts pushed to IT channels.

Standard multi-branch manufacturing and retail sales logs lacked automated general ledger sync, causing reconciliation errors.

Engineered custom POS consolidation programs and integrated inventory ledger records directly into ACCPAC and SAP ERP modules.

Scattered employee service requests and Human Capital ticket allocations led to unmanaged tasks and administrative delays.

Programmed a highly responsive web-based HR Service Desk portal managing master employee files, ticket routing logs, and analytical reports.

Legacy energy component telemetry databases needed severe migrations without introducing operational downtime on active processing sites.

Upgraded Natuna Energy Component database servers to version 12, mapping legacy database schemas, optimizing indexes, and verifying data pipelines.

National social welfare datasets (SIKSNG) suffered high latency under millions of concurrent regional queries, stalling local administrative aid.

Developed high-speed database query engine, optimizing tables partitioning, advanced indexes, and tuning high-concurrency APIs.

Rig logistics managers struggled to audit rig driver activities, outstation benefits, and fleet transport costs across scattered rig zones.

Developed a customized general affair driver tracking mobile application with offline GPS-logging, Rig area master data, and salary report modules.

Scaling Indonesia's flagship digital training academy portal to handle millions of annual visitors, complex course selection tests, and high-concurrency certificate validations.

Engineered a decoupled national system using Laravel as a high-throughput REST API server, React/Next.js for the optimized client-side interfaces, and a highly indexed PostgreSQL cluster.
