IT Consulting in Corona, CA

Working with Corona Businesses

Rofsky LLC provides hands-on IT consulting to Corona businesses from a home base in Eastvale, roughly 10 minutes down the 91. Corona sits at the western gateway of the Inland Empire, and its business mix reflects that position: manufacturing operations along Magnolia Avenue, light industrial shops near the Prado area, and a growing number of mid-sized service companies that have outgrown their original tech setups. Arthur Rofsky, the principal consultant, has worked directly with businesses in this corridor for years and understands the particular pressures that come with running operations in a logistics-heavy region.

Whether the work involves untangling a messy ERP migration for a manufacturing floor, standing up AI-driven automation for a service company’s intake process, or acting as a fractional CTO for a growing operation that is not ready to hire a full-time executive, the engagement always starts with the same thing: understanding what the business actually needs, not selling a product.

Corona’s manufacturing and distribution businesses often face a specific challenge. They adopted software years ago that mostly works but has become brittle and expensive to maintain. Rofsky specializes in exactly this kind of situation, taking what exists, evaluating what is worth keeping, and building a clear path forward without blowing up operations in the process.

What Corona Businesses Typically Need

• Fractional CTO services – Senior-level technology leadership on a part-time or project basis. Ideal for companies doing $2M-$20M in revenue that need strategic guidance without the $250K salary commitment.
• AI automation – Practical, production-ready automation using modern AI tools. Document processing, customer communication workflows, inventory forecasting, and internal process automation that actually saves time rather than creating new problems.
• WooCommerce and ERP integration – Connecting ecommerce storefronts to back-office systems like NetSuite, QuickBooks Enterprise, or industry-specific ERPs. Clean data flow from order to fulfillment to accounting.
• Application rescue – Taking over projects that a previous developer or agency left in a broken or half-finished state. Stabilizing, documenting, and getting things running properly before deciding on next steps.
• Legacy system modernization – Moving off outdated platforms, replacing Access databases, upgrading from on-premise servers to cloud infrastructure, and migrating away from end-of-life software without losing critical business data.

Why Local Matters

Most of the work happens remotely. Screen shares, async communication, and modern project management tools make that efficient and practical. But some conversations are better in person. When a manufacturing operation needs someone to walk the floor and understand how the production line actually connects to the software, or when a leadership team wants to hash out a technology roadmap face to face, being 10 minutes away in Eastvale makes that easy. There is no travel fee, no day-rate surcharge for on-site visits. Corona is local, and that proximity matters when the work gets complex.

How to Start

The first step is a conversation, not a pitch deck. Call (949) 704-0969 or use the contact form to describe what is going on. A short call is usually enough to figure out whether the engagement makes sense and what the scope might look like. Rofsky works with a small number of clients at a time, which means direct access to a senior consultant rather than being handed off to a junior team member. If the fit is right, an initial assessment or project scope typically comes together within a few days.
