I build products by understanding the systems underneath them.
Product engineering / Systems / AI
Build.
Break.
Understand.
Rebuild.
Implementation exposes the real system: its constraints, failure modes, and the decisions hidden below the interface.
Corporate Cruise
One mobility product, built across the interfaces and infrastructure that keep an office commute moving.
Real Corporate Cruise interface capture will live here.
Reserved for verified admin or driver workflow evidence.
Not a single screen. A connected service shaped by public journeys, protected workflows, live operations, and production constraints.
- 01
Public experience
Product positioning, service discovery, and the first layer of trust.
- 02
Client system
Authenticated journeys, service workflows, and operational visibility.
- 03
Operations / admin
Control surfaces for the people coordinating a live mobility system.
- 04
Driver system
Focused workflows for assignment, service progress, and field execution.
- 05
Backend / infrastructure
APIs, authentication, databases, live state, deployment, and routing logic.
How I build
Capability makes more sense as a stack of connected responsibilities.
- 01
Interface
React / Next.js / TypeScript
Responsive product surfaces with clear behavior and durable UI architecture.
- 02
Application
Node.js / APIs / Auth / Jobs
Business flows, protected boundaries, background work, and service contracts.
- 03
Data
PostgreSQL / MongoDB / Redis
Persistent records, operational models, caching, and live system state.
- 04
Infrastructure
Linux / Nginx / Cloud / Deployment
The runtime and delivery layer that turns an application into a working service.
- 05
Intelligence
LLMs / Agents / RAG / Automation
Applied experiments that connect models to real tools, context, and workflows.
Currently
Going deeper into engineering fundamentals while continuing to build product systems, explore AI, and sharpen frontend execution.
