Where Mathematics Meets the Architecture of Code

STATUS: ACTIVE PROFILE
SOURCE: LINKEDIN TRANSMISSION VERIFIED
Engineering & Foundations PROD.VER(4.2)

I am a Senior Full-Stack Engineer and Product Architect with a deep mathematical foundation. Like Euler's identity unifies fundamental constants, I unify system architecture, real-time engines, and AI-integrated applications into scalable, production-ready solutions.

From multi-tenant SaaS platforms to government-scale GIS systems, I approach every engineering challenge as a mathematical proof: seeking the most elegant, scalable, and computationally efficient solution.

    The Numerical Solution by Modified Adomian Decomposition Method for General Wave Equation

    Jeriko Abadi Putra, Muhammad Alfa Ridzi, Hafnani, Rahma Zuhra · Jul 2019

    SCIENCE AND TECHNOLOGY FOR NATION PROSPERITY, The 2nd International Conference on Science and Technology, Bengkulu, 6 - 7 Juli 2019, Bengkulu, UNIB Press, 77-85, 978-602-5830-19-8.

    The Adomian decomposition method and its modification are great methods used to solve a nonlinear equation in calculus of variations. Many researchers work in this method to solve problems in mathematics, physics, biology, and chemistry. In this paper, we apply modified Adomian decomposition method for wave equation problem. Then, we compare the result to exact solution and ordinary Adomian decomposition method. By using software MATLAB, we also plot the numerical solution to this problem.
