Data Engineer | SQL & Database Performance Specialist

Saya adalah Data Engineer dengan pengalaman lebih dari 7 tahun dalam pengelolaan database dan optimasi performa query, dengan fokus utama pada PostgreSQL dan Oracle.

Saya juga memiliki pengalaman dalam melakukan tuning pada berbagai sistem database lainnya, baik RDBMS maupun Big Data environment.

Saya terbiasa menangani permasalahan seperti query lambat, bottleneck pada sistem, serta inkonsistensi data yang berdampak langsung pada performa aplikasi. Fokus saya adalah memastikan sistem berjalan lebih cepat, stabil, dan efisien.

Beberapa hal yang biasa saya kerjakan:

• Optimasi query (dari detik/menit menjadi milidetik)
• Perbaikan struktur database dan strategi indexing
• Analisa dan tuning performa API berbasis database
• Debugging issue yang berkaitan dengan data

Saya mengutamakan solusi yang tepat sasaran, clean, dan mudah di-maintain untuk jangka panjang.

Siap membantu menyelesaikan permasalahan database Anda dengan cepat dan efektif.
