Custom Software
One system that matches your real process, instead of four tools and a spreadsheet holding the gaps together.
Founder-led software studio · New Jersey
DeviceBytes Software builds mobile apps, customer portals, internal dashboards, and workflow systems for growing service businesses, startups, and nonprofits.

What we build
Most projects start as one of these and grow into two. The discovery sprint works out which.
One system that matches your real process, instead of four tools and a spreadsheet holding the gaps together.
A portal takes the ten repeated questions off your phone and puts them behind a login, answered accurately, at two in the morning.
Cross-platform apps in React Native and Expo — including the background, permission, and store-review work that decides whether an app actually ships.
Connect the tools you already pay for, and let the handoffs happen without someone remembering to do them.
A first version scoped to answer the one question your idea actually depends on — built to ship, not to demo.
Ongoing maintenance for software we built or inherited — security updates, platform changes, fixes, and steady improvement.
Selected work
Each case study documents what was built, the problems that came up, and how they were solved. Every project is labelled with exactly what kind of work it was.

A skill-based matchmaking app that pairs golfers with compatible playing partners nearby, then gets the round on the calendar.
In development — store listings in progress

A hands-free mileage logger that detects drives in the background and turns them into IRS-ready deductions, with every GPS point kept on the device.
In development — store listings in progress

A service-operations dashboard bringing IT assets, vendor contracts, backup checks, and service performance into one view instead of six spreadsheets.
Self-directed concept build — modelled data, not a live client system

A role-based mobile app helping tenants, property owners, and case handlers coordinate Section 8 housing voucher matches in one workflow.
University team project, Fall 2024 — built with multiple contributors
Where this fits
These are the situations the work in our case studies actually covers — not an exhaustive list of industries.
Repair shops, field service, and trades running operations across spreadsheets, tickets, and text messages.
Anything that depends on where something is — routing, tracking, mapping, or capturing trips in the background.
Products that live on a phone and have to survive app review, background limits, and both platforms at once.
Systems coordinating several groups of people with different permissions and different jobs to do.
First versions scoped to test one assumption, built so version two does not start from scratch.
Dashboards that surface exceptions and next actions rather than another wall of totals.
How we work
Discovery is priced on its own and produces something useful whether or not you build with us.
A call, then a paid discovery sprint that maps the workflow you actually run — including the parts that only exist in someone's head.
Scope, data model, and a fixed-price proposal with milestones. You can stop here and take the output elsewhere.
Screens and flows for the paths that matter, resolved before they are expensive to change.
Working software in your hands early and often, with weekly progress you can see rather than a status report.
Deployment to your own accounts, store submission where relevant, and documentation for whoever comes next.
Security updates, platform changes, and steady improvement, so the software keeps matching the business.
Who you work with
DeviceBytes Software is founder-led. The person mapping your workflow is the person writing the code, so nothing is lost handing a project from a sales conversation to a delivery team.
Philip builds across React Native and Expo on mobile, React and Node or Flask on the web, PostgreSQL and SQLite for data, and Google Cloud for deployment — plus machine-learning research work through Drew University. He also runs IT operations at DeviceBytes, which is where a lot of the opinions about operations software come from.

Let's turn it into a clear, buildable plan. A first call is a conversation about your workflow — not a sales pitch, and not a commitment.
