01 / Overview

Engineering Philosophy & Impact

I am a backend and distributed systems engineer passionate about designing fault-tolerant architectures that operate reliably under intense scale. Over the past 9+ years, I have engineered systems spanning nationwide e-commerce platforms, distributed IoT telemetry pipelines, network monitoring infrastructure, and autonomous AI agents.

My core strength lies in translating complex real-world hardware and transaction challenges into decoupled, observable, and resilient software. Whether synchronizing edge telemetry across thousands of smart battery stations, ensuring 100% order accuracy in high-stakes pharmaceutical workflows, or orchestrating multi-agent LLM systems with Model Context Protocol (MCP), I prioritize architectural simplicity, data integrity, and measurable business impact.

Senior Backend & Systems Engineer

High Impact

PT Energi Kreasi Bersama (Electrum)

2025 – Present

Jakarta, Indonesia

→ Engineered high-throughput Go IoT gateway microservices and binary protocol decoders, streaming millions of real-time edge telemetry events from distributed battery swapping stations and smart battery management systems (BMS).
→ Architected remote binary diagnostic extraction pipelines (intake with auto-acknowledgment and flow-bounded retransmission) to reliably pull, reassemble, and persist edge device diagnostic logs over cellular IoT networks.
→ Re-engineered core energy billing calculation engine to price battery swaps based on real-time State-of-Health (SOH) electrochemical degradation, ensuring strict financial and transaction integrity across thousands of daily swaps.
→ Designed and automated Over-The-Air (OTA) firmware upgrade state machines and validation pipelines, enabling safe, non-disruptive firmware rollouts across heterogeneous hardware models in edge swapping cabinets.
→ Implemented enterprise-grade P0 anomaly detection in VictoriaMetrics/MetricsQL (covering thermal runaway, tracking loss, and protection faults) paired with an intelligent 15-minute alert digest proxy, slashing MTTD to under one minute and eliminating alert fatigue.
→ Hardened distributed Kafka event streaming and CDC pipelines (Debezium + PostgreSQL) with zero-loss delivery guarantees across high-concurrency transactional workers and observability sinks.

Backend Engineer

PT Bangunindo Teknusa Jaya

2024 – 2025

Jakarta, Indonesia

→ Modernized core telemetry forwarding engines (trap2json in Go), upgrading protocol integrations to Zabbix 7.2 and streamlining JSON-RPC API client communication.
→ Architected containerized end-to-end integration test suites using testcontainers-go, orchestrating multi-container networks (Zabbix Server, Proxy with SQLite, Postgres, MQTT) for telemetry validation.
→ Engineered automated Go microservices to ingest, scrape, and migrate legacy Cacti network weathermap topology data into centralized real-time Grafana dashboards.
→ Built and maintained Python/Flask authentication services and workers governing non-domain user access, session auditing, and security compliance on production jumphosts.

PT Tokopedia

2022 – 2024

Jakarta, Indonesia

→ Engineered the e-Pharmacy backend service, boosting prescription drug order accuracy from 95% to 100% by architecting a resilient distributed backfilling mechanism using NSQ.
→ Prevented millions of rupiah in potential revenue loss by diagnosing and resolving a high-concurrency race condition affecting 200+ transactional orders.
→ Designed and scaled high-performance Go microservices communicating via gRPC to withstand peak flash-sale e-commerce traffic spikes.
→ Authored comprehensive Technical Requirements Documents (TRD), optimized complex PostgreSQL schemas, and led code reviews across cross-functional squads.
