Hi, my name is
Alfiansyah Pradinata Putra
Architecting robust backend systems, multi-tenant SaaS, and high-performance web applications with clean, scalable code.
About Me
Hello! I'm Alfiansyah Pradinata Putra, a software engineer with a rigorous foundation in informatics and practical engineering experience delivering enterprise and startup solutions.
With 6 months of professional enterprise experience at PT Sentra Vidya Utama (SEVIMA), I engineered multi-tenant admission platforms with Go and PostgreSQL, developed modern administration systems with Next.js 16 and Prisma ORM, and built intelligent Python Playwright scrapers that cut manual workload by 80%.
As Founding Engineer at RevuTap (Multi-Tenant NFC Review & Local SEO Platform), I commercialized an end-to-end SaaS that manufactured and deployed 100+ active custom NFC devices for SMEs, engineered an edge redirection engine handling 403,000+ read spikes at <100ms latency, and hardened platform integrity with AES-256-GCM token encryption and Cloudflare Turnstile.
I graduated from Politeknik Negeri Jember with a Diploma III in Informatics Management, achieving a cumulative GPA of 3.75 / 4.00. My capstone thesis focused on developing an algorithmic Decision Support System (DSS) using the Analytical Hierarchy Process (AHP) for heart disease nutrition planning.
