Modernization

Moving a live product to a better foundation without making users feel the transition

A live architecture migration handled with stability, coordination, and no user-facing disruption.

At Onaroll, I stepped into a short but high-impact role as a hands-on Engineering Manager. The company’s flagship product supported rewards, performance improvement, and goal tracking for shift workers in the hospitality industry. The product was live, active, and important to the business.

One of the biggest projects I led there was a major architecture migration from Heroku and Create React App to Next.js and Vercel. A migration like that is not just a technical checklist. It affects deployment, reliability, developer workflow, performance, and the team’s ability to keep building after launch.

The goal was to modernize the foundation without disrupting users. That meant coordinating carefully, testing thoroughly, working across product and design, and keeping the team aligned on both the technical plan and the business risk.

The migration launched with zero defects and no user downtime. During that same role, I also coached a junior engineer from a PIP to promotion, hired and onboarded an engineer, and worked closely with product and design to support product strategy and timelines.

How this applies

The same pattern shows up in smaller business systems too.

The scale may change, but the work still starts the same way: understand what is really happening, organize the moving parts, then build the next useful thing.

MethodMade translation

For a small business, that might mean clearer service pages, cleaner intake, better follow-up, usable documentation, or one practical automation.

1

Understand the real situation

Start by separating the visible problem from the actual workflow, people, tools, constraints, and risks underneath it.

2

Organize the moving parts

Turn the scattered pieces into a clearer map: what exists, what matters, what is missing, and what should happen next.

3

Build the next useful system

Create the practical next layer: a page, process, automation, document, or tool that can be understood and maintained.
