I build products by understanding the systems underneath them.

Product engineering / Systems / AI

01Origin

Build.

Break.

Understand.

Rebuild.

Implementation exposes the real system: its constraints, failure modes, and the decisions hidden below the interface.

02Builds

Corporate Cruise

One mobility product, built across the interfaces and infrastructure that keep an office commute moving.

Primary product evidenceScreenshot pending

Real Corporate Cruise interface capture will live here.

Operations surfaceScreenshot pending

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.

  1. 01

    Public experience

    Product positioning, service discovery, and the first layer of trust.

  2. 02

    Client system

    Authenticated journeys, service workflows, and operational visibility.

  3. 03

    Operations / admin

    Control surfaces for the people coordinating a live mobility system.

  4. 04

    Driver system

    Focused workflows for assignment, service progress, and field execution.

  5. 05

    Backend / infrastructure

    APIs, authentication, databases, live state, deployment, and routing logic.

03Under the hood

How I build

Capability makes more sense as a stack of connected responsibilities.

  1. 01

    Interface

    React / Next.js / TypeScript

    Responsive product surfaces with clear behavior and durable UI architecture.

  2. 02

    Application

    Node.js / APIs / Auth / Jobs

    Business flows, protected boundaries, background work, and service contracts.

  3. 03

    Data

    PostgreSQL / MongoDB / Redis

    Persistent records, operational models, caching, and live system state.

  4. 04

    Infrastructure

    Linux / Nginx / Cloud / Deployment

    The runtime and delivery layer that turns an application into a working service.

  5. 05

    Intelligence

    LLMs / Agents / RAG / Automation

    Applied experiments that connect models to real tools, context, and workflows.

04Current state

Currently

Going deeper into engineering fundamentals while continuing to build product systems, explore AI, and sharpen frontend execution.
