Software Engineer focused on building scalable backend systems, high-throughput pipelines, and production-ready applications.
7+ years shipping reliable software across enterprise platforms, distributed services, and AI/LLM production workflows.
- Scaled backends to millions of requests/day — architected and operated the backend for an internal enterprise field operations platform serving a nationwide FMCG distributor with sub-100ms response times.
- High-throughput ETL & reconciliation — engineered nightly cron pipelines and asynchronous export jobs synchronizing tens of thousands of records across distributed enterprise services with zero manual overhead.
- Distributed 50,000 vouchers with zero double-redemption — built a high-concurrency campaign delivery system over official WhatsApp Business API with pessimistic locking and explicit transaction isolation.
- Fraud-resistant payment disbursement — developed a Midtrans Iris payout service enforcing one-claim-per-verified-phone with row locking and request throttling to prevent abuse.
- Database & Query Optimization — resolved query bottlenecks on Microsoft SQL Server, PostgreSQL, and MySQL through advanced indexing, query restructuring, and connection tuning for enterprise CRMs.
- LLMs & RAG in production — integrated LLMs into automated content generators and engineered RAG chatbots with persistent vector memory for continuous context learning.
- Integration middleware — built an OAuth2 webhook-routing layer sustaining high-volume partner calls with automatic retries for guaranteed zero data loss.
- Automated CI/CD & Delivery — wired Dokploy staging previews and self-hosted GitLab runners into CI/CD for fully automated, hands-off deployments.
