Software Engineer | Spesialis Web, Mobile, & Integrasi Sistem IoT

Halo! Saya Rayhan Yupila Putra, seorang Software Developer yang berfokus pada pengembangan perangkat lunak terintegrasi, mulai dari sistem berbasis web, aplikasi mobile, hingga solusi Internet of Things (IoT) dan pengolahan data.

Saya terbiasa menangani proyek teknis dari tahap perancangan arsitektur hingga implementasi (Full-Stack), dengan pengalaman langsung dalam mengembangkan sistem skala industri seperti aplikasi pembelajaran berbasis web dan sistem aviasi terpadu. Saya berorientasi pada penyelesaian masalah (problem-solving) dan selalu memastikan sistem yang dibangun berjalan efisien, aman, dan mudah dikelola (maintainable).

Keahlian & Layanan Teknis yang Saya Tawarkan:

Web Development (Backend & REST API): Perancangan sistem web dinamis dan pembuatan API menggunakan PHP, Python (Flask), serta manajemen database MySQL.
Mobile Development: Pembuatan aplikasi mobile lintas platform (Android/iOS) menggunakan Flutter yang terintegrasi dengan Firebase (Realtime Database).
IoT & Embedded Systems: Perancangan sirkuit dan firmware kustom menggunakan ESP32/Arduino, integrasi berbagai sensor (suhu, kelembapan, analog/digital), hingga sistem otomatisasi hardware.
Data Science & Machine Learning: Implementasi model prediktif (seperti K-Nearest Neighbors / KNN), pengolahan dataset, dan normalisasi data menggunakan Python.

Mengapa Bekerja Sama dengan Saya? Saya tidak hanya menulis kode, tetapi merancang solusi. Baik Anda membutuhkan perbaikan bug database, pembuatan aplikasi dari nol, atau purwarupa hardware cerdas yang terhubung ke aplikasi mobile, saya siap mendiskusikan kebutuhan Anda dan memberikan hasil pekerjaan yang berkualitas, tepat waktu, serta sesuai dengan anggaran.

Mari diskusikan detail proyek Anda, dan saya siap membantu mewujudkannya!
