Custom software development

Custom software, built to the max.

Max Dev designs and builds web platforms, multiplayer games, online stores and connected hardware — from the first sketch to something people actually use.

Things we’ve built and shipped.

Six products, four very different platforms — classroom games, a storefront, messaging, and hardware you can hold in your hand.

Web platform · Games

BloopCade

Classroom games you join with a code. Teachers bring their own questions — or import them from Kahoot, Gimkit, Blooket or Quizlet — and students play live, earn BlooBucks and collect original Bloop characters. No ads, no trackers, no email needed.

E-commerce

Kelly Print Co

The online shop for a small 3D-print studio selling handmade, print-in-place “squirmies”. Shoppers spin a live 3D preview that recolors as they pick filament, then check out with Stripe. Custom print quotes and a maker license are built in.

Comms Games

A game arcade that lives in a Google Docs sidebar. Built for a Communications class, with favorites, leaderboards, staff tools and real-time multiplayer — including our original game, Knockback — plus a public web edition.

InSightME

A messaging and community app for teens: groups with channels, DMs, a social feed with polls, encrypted group chats, one-tap translation and built-in moderation — plus a developer portal with webhooks and bots.

Hardware · IoT

Smart Spool

RFID filament tracking for Bambu Lab 3D printers. Tap a tagged spool on the ESP32 reader and its material, color and temperatures go straight to the printer’s AMS slot — so print profiles follow the spool. Open-source firmware, a MakerWorld browser extension and a clip-on printed mount.

Remote for Samsung TV

A custom touchscreen remote for Samsung’s The Frame, built on an ESP32. It talks to the TV over the local network — no cloud account, nothing to expire — with app shortcuts, true Art Mode control, Wake-on-LAN and a 3D-printed case.

What we do

From pixels to printed circuits.

We work across the whole stack — interface, backend, infrastructure — and off the screen too, when a project needs a device in your hand.

Web apps

Real-time platforms with accounts, databases, dashboards and admin tools — built to feel fast.

Multiplayer games

Browser games with authoritative servers and live netcode running on the edge, close to every player.

Online stores

Storefronts with Stripe checkout, subscriptions, interactive 3D product previews and order emails.

Hardware & IoT

ESP32 firmware, touchscreens, RFID and custom PCBs that talk to the devices you already own.

Workspace add-ons

Tools that live right inside Google Docs and Sheets, built on Apps Script and deployed to your team.

Enclosures & mounts

Cases, keypads and mounts modeled in code and 3D-printed, so the hardware looks as good as it works.

How we work

Idea in. Product out.

A simple loop we run on every project, whether it’s a weekend prototype or a full platform.

  1. Discover

    Start with the problem, not the tech: who it’s for, what “done” looks like, and what really matters.

  2. Design

    Sketches and clickable prototypes early, so you can react to something real instead of a spec.

  3. Build

    Small, working releases you can try as we go — tested properly, not just demoed.

  4. Launch & support

    Ship it, watch how people use it, and keep improving it long after launch day.

About Max Dev

Small studio. Full stack. Real products.

Max Dev builds custom software end to end — the interface, the backend, the infrastructure, and when a project calls for it, the circuit board and the case it lives in. Every project on this page went from an idea to something people use every day.
