SEC_01

I'm Rayhan, a Full-Stack System Architect. I love taking complex software requirements and engineering them into elegant, high-throughput web ecosystems — taking products from 0 → 1 with precision, or scaling them from 1 → 100 under real-world traffic.

My work spans architecting modular monorepos (like the Rayeen Ecosystem encompassing WMS, NuraFin, Tdash, Creatify, and Admin), to mission-critical university academic systems for UNISMA serving tens of thousands of active records.

I believe great software is born at the intersection of rigorous backend architecture, resilient data integrity, and high-density, beautiful interfaces that respect the user's time and focus.

Modular Monorepos

Self-contained micro-applications running on shared type systems and unified tokens.

Zero-Jank Performance

Optimistic updates, server-side data loaders, and sub-millisecond edge API execution.

Zygote Data Integrity

Audit-logged soft deletes, universal UUID public keys, and strict Zod runtime schemas.

Experience & Leadership

SEC_02

A track record of engineering leadership, scalable product delivery, and technical stewardship across private labs and university enterprise systems.

Designing and orchestrating a multi-app monorepo ecosystem with independently deployable micro-frontends and high-throughput Hono/PostgreSQL backends.

Key Impacts & Responsibilities:
  • Built 6+ enterprise & productivity applications (WMS, NuraFin, EIS, Campus ERP, Creatify, Admin) running on unified design tokens and shared core libraries.
  • Architected Zygote data model standards and AI Bridge bug tracing mechanism with automatic issue resolution workflows.
  • Engineered high-performance SSR and sub-millisecond client transitions using React Router v7 and optimized edge bundling.

Leading the development and diagnostic modernization of mission-critical campus systems serving thousands of students and faculty members.

Key Impacts & Responsibilities:
  • Architected automated diagnostic engines for SIAKAD student data integrity (Yudisium study period audit, SKS accumulation, and PDDikti feeder reconciliation).
  • Developed Ormawa Activity Proposal & Budgeting System with multi-tier approval matrix and real-time financial tracking.
  • Engineered alumni Tracer Study platform with complex analytical surveys and interactive accreditation reports.
