Perkenalkan, saya Leonardo Tatulus, Full Stack Developer dengan 4 tahun pengalaman dalam merancang, mengembangkan, dan memelihara aplikasi skala enterprise terintegrasi (Mobile & Web). Fokus keahlian saya berada pada ekosistem React Native, Flutter, NodeJS, dan SQL.

Saya memiliki rekam jejak yang solid dalam membangun arsitektur sistem kompleks untuk kebutuhan operasional bisnis yang spesifik. Beberapa portofolio utama saya mencakup pengembangan Warehouse Management System (WMS), Port Management, Point of Sale (POS), Mobile Attendance, hingga Fleet Management System untuk industri pertambangan yang mengimplementasikan arsitektur offline-first untuk area minim konektivitas.

Keahlian Teknis Utama:

  • Mobile App Development: React Native & Flutter (Fokus pada performa, sinkronisasi data real-time, dan kapabilitas offline).

  • Backend & Database: NodeJS & SQL (Desain API yang aman, manajemen state yang kompleks, dan skalabilitas data tingkat tinggi).

  • Domain Bisnis: Logistik, Inventaris, Manajemen Aset, dan Sistem Operasional Korporat.

Pendekatan kerja saya sangat berorientasi pada hasil dan stabilitas jangka panjang. Saya menerapkan standar penulisan kode yang bersih (clean code), struktur database yang optimal, dan dokumentasi yang rapi sehingga perangkat lunak tidak hanya berfungsi saat dirilis, tetapi juga mudah dipelihara dan dikembangkan di masa depan.

Saya terbiasa berkomunikasi secara profesional untuk membedah kebutuhan teknis klien dan memberikan solusi arsitektur yang paling efisien, baik dari segi performa maupun anggaran.

Mari diskusikan detail teknis proyek Anda, dan saya siap membantu mewujudkan sistem yang tangguh untuk bisnis Anda.
