Custom Development & Integrations
Every growing business eventually hits a problem no plugin solves — a pricing engine, a customer portal, an app your crew needs in their pocket. We design and build custom software with real engineering underneath — Java and Spring Boot APIs, React and Next.js frontends, native mobile and desktop apps — and we support it for the long haul.

Sound familiar?
Spreadsheets feeding spreadsheets, staff bridging gaps between systems by hand, and processes held together by the one person who knows how. It works — until it doesn't scale.
You've stacked plugins that each do 80% of the job. The stack conflicts, slows the site, and the missing 20% is the part your business actually needed.
The industry tool you bought years ago doesn't match how you work now, and the vendor's roadmap doesn't care about your use case.
You know what would give you an edge — a customer portal, a quoting tool, an internal app — but you don't have a team to design, build, and maintain it.
What you get
Custom plugins built to WordPress standards — functionality that fits your site instead of fighting it, without the bloat of five almost-right plugins.
Customer portals, quoting and configuration tools, booking systems, dashboards — React and Next.js applications over properly engineered APIs, designed around your workflow and your data.
For jobs that live in a pocket or on a workbench — field apps for crews, ops apps for the shop floor, desktop tools for the back office. Built native, synced to the same backend as everything else.
Spring Boot APIs on PostgreSQL with clean architecture throughout — internal tools, ERPs, and platforms built to replace the subscriptions your business has outgrown, and to outlast them.
Complex product logic — measurement-based pricing, configurators, industry-specific units — built for stores whose catalogs defeat generic solutions.
The small, unglamorous apps that remove hours of manual work — approval flows, data entry screens, report generators — built quickly and maintained properly.
We document, secure, and maintain what we build. Custom software from us doesn't become orphaned code.
The best custom software usually isn’t ambitious — it’s specific. A tool that turns a four-hour weekly task into a button. A portal that ends “just emailing the spreadsheet.” A pricing engine that quotes in your industry’s units. We’ve built technology in environments from small businesses to Fortune 500, and the lesson is the same at every scale: solve the actual bottleneck, ship it small, and improve it with evidence.

Part of a system
No solution we build stands alone — each one is designed to hand off cleanly to the others.
Proof
Retail / Legacy CMS Rescue
A long-standing Michigan retailer's aging Joomla website had become a security liability. We rebuilt it as a modern static site, moved it to hardened infrastructure — and when a DDoS attack came, the site stayed up.

Process
What the current process costs, who touches it, and what "solved" looks like in numbers.
We'd rather ship a focused tool in weeks than a platform in a year. Scope grows with proof.
Clear milestones, working software you can react to early, and honest conversations when tradeoffs appear.
The people who'll use it daily test it before launch — their friction is the punch list.
Documentation, maintenance, and iterative improvements as the business changes.
Questions
Run the math with us. If an off-the-shelf tool covers your need, we'll tell you — we implement plenty of them. Custom wins when the manual cost is ongoing, the need is specific to how you compete, or the "almost right" tools create more work than they remove.
A committed stack, not a menu — Java 21 and Spring Boot for backends, PostgreSQL for data, React and Next.js for applications, native tooling for iOS, Android, and desktop, and PHP/WordPress where plugin work calls for it. We optimize for maintainability over novelty, because you'll live with this code for years — and maintenance should never turn into archaeology.
You do. Full source, documentation, and the right to take it anywhere. We aim to keep your business because the work is good, not because you're locked in.
Software needs upkeep — security updates, compatibility, small improvements. We offer ongoing maintenance for everything we build, and most clients keep us on because the same team that built it can change it fastest.
Tell us what is working, what is not, and where you want the business to go. We'll help you determine the smartest next step — no pressure, no jargon.
