Background & Expertise

Bridging Deep Technical Engineering with Strategic Business Impact

I specialize in transforming intricate, data-heavy operational processes into high-speed, scalable software systems and crystal-clear business intelligence.

My professional journey combines the analytical precision of a Certified Google Cloud Professional Data Engineer with hands-on software development and user-centered design. Throughout my career, I have focused on solving real bottlenecks in high-velocity supply chain, e-commerce, and enterprise finance ecosystems.

At PT Jeje Harapan Transindo, I transformed legacy spreadsheet systems into an enterprise-grade TypeScript financial SPA (FATrack). By diving deep into database execution plans, I refactored slow relational queries from over 30 seconds to sub-second (<1s) execution, eliminated financial floating-point rounding errors via strict zero-threshold arithmetic, and automated the extraction of over 3,700 Proof of Delivery documents per cycle.

Previously at PT Titipbeliin Global Internasional, I analyzed cross-border e-commerce operations across SAP FI/SD modules and end-user platforms, pinpointing bottlenecks to boost monthly GMV by IDR 2.2 Billion while managing end-to-end quality assurance across 153 UAT test cases.

Whether architecting denormalized ClickHouse data marts, authoring PRDs in Jira, or deploying autonomous AI agent workflows with Gemini and n8n, my philosophy is grounded in one principle: technology must create measurable, defensible operational value.

Core Engineering Principles
  • Defensive Data IntegrityZero-tolerance for financial calculation anomalies, strict |n| < 1 thresholds, and complete audit logging.
  • Sub-Second ScalabilityOptimizing B-tree indexes, eliminating unindexed OR joins, and decoupling OLAP analytical loads from OLTP clusters.
  • Autonomous WorkflowsCombining rule-based state machines with Google Gemini AI natural language processing to eliminate repetitive clerical work.

Database & Performance Engineering

Specialized in high-throughput PostgreSQL stored procedures (PL/pgSQL RPCs), query plan optimization (from 30+s to <1s), CTEs, LATERAL joins, and ClickHouse OLAP denormalization.

Financial & Logistics Reconciliation

Automated Account Receivable engines, DJP Coretax compliance (DPP, PPN 11%/12%, PPh 2%), logistics claims liability burden-splitting, and multi-entity debt ledger state machines.

AI & Workflow Automation

Engineering 24/7 operational WhatsApp bots integrated with Google Gemini AI, n8n workflow webhooks, and PostgreSQL logging, saving 40+ hours of manual administrative overhead per month.

Product Analytics & UI/UX Design

Translating complex logistics workflows into intuitive Figma design systems, authoring TMS Product Requirement Documents (PRDs), and executing comprehensive UAT testing (150+ test cases).
