Engineering & Prototyping Studio
From software to physical hardware, built by one team.
ProtoNexa3D designs and builds software, connected devices, and physical products — covering software engineering, IoT, PCB design and fabrication, 3D printing, and laser cutting under one roof.
What We Do
Each capability can be hired on its own, or combined to take a product from concept to a working, tested build.
Software Engineering
Custom software and embedded applications built to run on real hardware, not just in a browser.
Web, iOS & Android Development
Websites and native iOS and Android apps, designed and maintained end-to-end.
IoT Development
Connected devices — sensors, RFID/NFC, wireless communication, and cloud integration.
PCB Prototyping & Making
Schematic design, PCB layout, and small-batch fabrication and assembly for custom electronics.
3D Printing
FDM and resin printing for functional prototypes, enclosures, and mechanical parts.
Laser Cutting & Engraving
Precision-cut enclosures, panels, and marking on wood, acrylic, and other sheet materials.
Our Approach
Software and hardware, under one roof
Most projects need code, electronics, and a physical build to come together. We keep that whole chain in-house, so your product moves from idea to working prototype without getting stuck between separate teams.
One team, not three vendors
Firmware, electronics, and enclosure design happen together, so nothing gets lost between handoffs.
Prototype fast, iterate often
In-house 3D printing, laser cutting, and PCB assembly mean design changes turn around in days, not weeks.
Built to be produced
Prototypes are designed with manufacturing and small-batch production in mind from the start.
IoT & Connected Hardware
From sensor to signal
We design and build the connected side of a product — the electronics, firmware, and communication layer that turn a physical object into a smart one.
Sensors & data collection
Environmental, motion, and usage sensors feeding data back for monitoring or automation.
RFID / NFC integration
Tag-based identification and access for asset tracking, check-in, and smart-object triggers.
Connectivity & cloud
Wi-Fi, BLE, and LoRa devices reporting to a backend or dashboard you can actually use.
Our Process
Every project goes through the same discipline, whether it's a one-off prototype or a small production run.
Design
Requirements, schematics, and 3D models translated into a build plan.
Build
3D printing, PCB fabrication, and laser-cut parts brought together into a working prototype.
Test
Firmware and hardware validated together before scaling up.
Deliver
Documentation, handoff, or small-batch production for your team.
