Early Career Story
Automotive Mechanic
ESL Express - PT.EKA SARI LORENA
Oct 2011 - Nov 2017 6 tahun 1 bulan
Before transitioning into software engineering, I spent six years as an automotive mechanic. That experience shaped my troubleshooting intuition, strengthened my ability to read system symptoms, and developed a hands-on approach to problem solving that still influences how I design backend systems today.
- Diagnosed, repaired, and maintained company vehicles
- Worked with passenger vehicles, trucks, and buses
- Built discipline, technical intuition, and practical ownership

Deep dives into backend architecture decisions, trade-offs, observability, and operational impact.
Centralized Distributed Logging System
Designed and implemented a centralized logging system enabling end-to-end request tracing across 10+ microservices.
Kafka MongoDB Kong Go OpenTelemetry
01. Client Request → API Gateway (Kong)
↓
02. Inject: request-id & app-request-id
↓
03. Stream to Kafka Topic
↓
04. Consumer → MongoDB (indexed storage)
↓
05. Complete traceability & chaining
Key Features
- Dual identifier system : request-id (chaining) & app-request-id (unique)
- Event-driven : Kafka for decoupled, scalable log streaming
- Optimized storage : MongoDB with indexing on both IDs
- End-to-end visibility from entry to response

Event-Driven Architecture: Topic-Based Messaging
Reorganized event message handling from fanout delivery to topic-based routing so each microservice consumes only the events it owns.
Challenge
Fanout exchange pushed every event to every queue and consumer. Services had to receive, inspect, and ignore irrelevant messages, creating roughly 75% wasted processing across four event domains.
Solution
Migrated to RabbitMQ topic exchange with selective binding patterns. Each consumer subscribes only to relevant topics such as order.*, payment.*, user.*, and stock.*, while multiple active consumers process events in parallel.
RabbitMQ Topic Exchange Go Microservices
01. Before: Fanout exchange broadcast all events to all consumers
↓
02. Consumers filtered and ignored unrelated event types
↓
03. After: Topic exchange routes events by binding pattern
↓
04. order.* → Consumer Order
↓
05. payment.* → Consumer Payment
↓
06. user.* → Consumer User
↓
07. stock.* → Consumer Stock
Key Features
- Selective binding : consumers subscribe only to topic patterns they own
- Multiple active consumers : event workloads can run in parallel
- Independent scaling : consumer pools scale per service workload
- Fault isolation : one consumer failure does not block unrelated domains
- Cleaner consumer logic : no ignore conditions for unrelated events
