FREELANCE JASA CFD FEA DAN CAD UMUM: CAESAR WIRATAMA

Halo, perkenalkan saya Caesar Wiratama, Lead engineer dari AE Services. Saya banyak bekerja untuk project-project engineering khususnya menggunakan software Computational Fluid Dynamics (CFD), FInite Element Analysis (FEA), maupun Computer Aided Design (CAD) secara umum; mulai dari perencanaan desain struktur, perancangan mesin, perhitungan performa peralatan fluida, mencari root cause dan solusinya, dan masih banyak lagi.

Kenapa harus freelance?

Kebutuhan data simulasi CFD, FEA, atau gambar teknik terkadang membutuhkan waktu yang singkat karena project yang berjalan menuntut deadline yang cepat agar keseluruhan project dapat berjalan dengan lancar. Oleh karena itu, perusahaan anda dapat menghire saya sebagai freelancer yang langsung bekerja pada project tersebut, sehingga memangkas birokrasi yang harus dilakukan antar-perusahaan.

Kenapa memilih saya?

Saya sudah masuk ke dunia simulasi CFD, FEA, dan gambar teknik sejak tahun 2013 sejak berkuliah di teknik mesin Universitas Gadjah Mada sebagai freelancer dan akhirnya membuat perusahaan jasa yang berdedikasi menghandle konsultasi engineering AE Services.

Bagaimana menghubungi saya?
