Senior software engineering
for Gurnee & Lake County.
Custom software, mobile apps, SaaS platforms, and AI integration — engineered for mid-market businesses across Gurnee, Waukegan, Libertyville, Lake Forest, and the north Chicagoland corridor. Led by a senior engineer who lives in Gurnee — your neighbor, not a Chicago Loop agency. One engineer. No layers. No markup.
Your neighbor, not a Chicago Loop agency
The engineer running Champlin Enterprises lives in Gurnee. Not "serves" Gurnee, not "has clients in" Gurnee — actually lives here, drives the same Route 41 you do, and knows the difference between Gurnee Mills traffic on a weekday and Six Flags traffic on a Saturday. Lake County businesses get the rare combination of senior engineering output and a software partner who is genuinely local. That alone changes the working relationship — meetings are easier to schedule, on-site is the default, and the relationship survives the long run because we are in the same community.
For the businesses along the I-94 corridor
Lake County is one of the strongest mid-market business corridors in the country — pharmaceutical, healthcare, manufacturing, distribution, professional services, and a deep bench of corporate satellite offices. The software needs are real. The Chicago Loop agencies are often a poor fit: too expensive, too layered, and too far removed from the business itself. Champlin Enterprises is built for businesses who want senior engineering without the agency overhead.
What we build for Lake County businesses
Custom internal software that finally replaces the spreadsheet. Field-team mobile apps for service techs, route sales, and inspections. SaaS platforms when an internal tool turns out to be a product worth selling. AI integration in document review, customer intake, lead qualification, and operations automation — the high-leverage AI work that actually changes a P&L. Always engineered, never templated.
Why one senior engineer beats an agency org chart
Most software projects fail not because the technology was wrong but because the architecture was decided by someone three layers removed from the business. Champlin Enterprises removes those layers. The same senior engineer who talks to your team on Tuesday writes the code on Wednesday and reviews it in production on Thursday. That tight loop is the actual product.
Across the north suburbs
The same engagement model serves Gurnee, Waukegan, Libertyville, Lake Forest, Vernon Hills, Lake Bluff, Highland Park, Deerfield, Buffalo Grove, and the broader Lake County and North Shore region. Remote-first when remote works, on-site when on-site matters.
What this looks like in practice
Custom software for mid-market
Operations, manufacturing, healthcare workflows, and back-office tooling — built around how your business actually runs, not a generic template.
Mobile for field and frontline teams
iOS and Android from one Kotlin Multiplatform codebase. Route sales, service tech dispatch, inspections, healthcare intake, retail floor tools.
SaaS platforms and spinouts
When an internal tool has product potential. Multi-tenant architecture, billing, auth, and SaaS plumbing — built for the day you decide to charge for it.
AI integration in production
Document processing, customer support, lead qualification, intake automation — the AI work that compresses hours of senior staff time per day.
FAQ
Common questions
What kind of Gurnee and Lake County businesses do you work with?
Mid-market manufacturers, healthcare practices, distribution companies, professional services firms, hospitality and retail businesses, and the large pool of corporate satellite offices along the I-94 corridor. The pattern is the same across them: a business that needs better software than off-the-shelf SaaS can give it, without paying Chicago Loop agency rates.
Is on-site work available in Gurnee, Waukegan, Libertyville, or Lake Forest?
Yes — and the engineer running Champlin Enterprises lives in Gurnee. On-site sessions, workshops, architecture reviews, and standing weekly working sessions across Lake County and the north suburbs are easy because this is home, not a service area on a map.
How is this different from a Chicago Loop agency?
A Chicago Loop agency layers project managers, account executives, and junior developers between you and the engineer doing the work. Champlin Enterprises is one senior engineer with 28 years of production experience writing every line. No telephone game, no agency markup, no introductory rates that quietly creep up.
How is this different from off-the-shelf SaaS or a low-code platform?
Off-the-shelf SaaS forces your business to fit the tool. Low-code platforms run into a wall the moment your workflow gets specific. Custom software fits your business — and after 28 years, the cost-and-time math is far better than most businesses expect.
Can you handle the full stack — backend, web, iOS, and Android?
Yes, all from one engagement and one engineer. iOS and Android share a Kotlin Multiplatform codebase. Backend is Laravel, Next.js, Node, or Python depending on the problem. You do not coordinate three vendors and three timelines.
What does engagement pricing look like?
Sprint engagements start at $10,000. Build engagements scale with the problem. Three quarterly engagement slots are available — booked in advance.
A softer step
Not sure if you even need this kind of work?
Most businesses don't need a custom build — they need 30 minutes of real conversation to figure out whether they do. That's what the Free AI Opportunity Audit is: thirty minutes on Zoom, three concrete places AI quietly pays for itself in your business, a one-page plan emailed within 48 hours. No pitch. No follow-up sales sequence. You keep the plan whether or not we ever work together.
