Concept to production, one partner
PCB design, embedded firmware, cloud and mobile software, and legacy hardware modernization from our San Diego engineering team, built in our ISO 9001:2015 certified contract manufacturing plant in Tijuana, minutes from the border.
About AGI
We are a team of engineers driven by a shared passion for technology, and by the belief that good engineering turns difficult problems into practical, reliable products.
With engineers in San Diego and Argentina, we combine deep hardware and electronics experience with embedded firmware, software, connectivity and system-level engineering. That lets us approach a product from every angle, whether we are developing something new, modernizing legacy electronics, solving a difficult hardware problem or connecting an existing product to the cloud.
Our goal is simple: understand the problem, find the right engineering solution, and make it work.
Engineering and manufacturing work side by side, so your design is built for production from day one and nothing gets lost in a hand-off.
Engineering
Full-service product engineering: hardware and PCB design, embedded firmware, cloud, web and mobile software, connectivity and system-level design.
Manufacturing
A US company with a 30+ year history in PCBA manufacturing. Its Tijuana facility, minutes from the San Diego border, offers competitive labor costs with the flexibility and logistics of a US-based company.
How the partnership works
Talk directly with the engineers who design and build your product, from the first call onward.
Background in embedded electronics, product development and system-level engineering — from designing satellite communication equipment to leading the electronic design team of a major ventilator manufacturer.
Extensive telecommunications experience, including his role as Operations Director at Claro Argentina. Today he focuses on web applications and connected systems, especially telecommunications and remote connectivity.
Your first point of contact for new projects. Reach out to discuss your product, your engineering needs or a manufacturing program, and he will bring the right people to the table.
Services
We turn ideas, engineering challenges, and existing products into working solutions — combining electronics, embedded systems, software, connectivity, and manufacturing expertise under one roof.
Engineering
PCB design, embedded firmware, connected software and legacy electronics modernization — handled by one engineering team in San Diego and Argentina, so hardware, firmware and apps are designed to work together.
Turn an idea or requirement into a practical engineering plan. We define system architecture, evaluate technologies, identify risks, and design the foundation for a successful product.
Reliable, production-ready electronics from schematic through PCB layout: analog and digital circuitry, power systems, high-speed interfaces, component selection, and mechanical integration.
Bring hardware to life with custom embedded firmware — from low-level microcontroller code to wireless communication, signal processing, device control, and complex real-time applications.
Build the software around your product: cloud services, web portals, iOS and Android apps, databases, and MQTT integrations for monitoring, configuration, control, and data management.
Take designs beyond the lab and toward production with prototyping, validation, testing, component selection, DFM improvements, failure analysis, and manufacturing troubleshooting.
Keep existing products and equipment working, even when the original technology is obsolete. We troubleshoot failures, modernize legacy systems, and develop retrofit solutions for products already in the field.
ISO 9001:2015 PCBA & box build in Tijuana with our partner American Green Inc.
From concept to production, we provide the engineering expertise to build, modernize, connect, and improve your products.
Discuss your projectHow we work
AGI System Developments and our manufacturing partner American Green Inc. take your product from concept to production under one roof, so nothing gets lost between the design house and the factory.
Step 01 of 5
We turn your idea or requirements into a practical engineering plan: system architecture, technology evaluation and early risk identification.
Step 02 of 5
Hardware and PCB design, embedded firmware, and the cloud, web and mobile software around it, with 3D modeling for mechanical integration.
Step 03 of 5
We build and test prototypes, validate the design, and feed DFM improvements and failure analysis back in before anything reaches the line.
Step 04 of 5
Turnkey PCBA (SMT, through-hole and mixed) and box build at American Green Inc.’s ISO 9001:2015 facility in Tijuana, with documented processes and testing.
Step 05 of 5
Packaging, labeling and shipping FOB San Diego to the US and abroad — then field support, troubleshooting and sustainment once your product is out there.
Two ways in — the same team either way.
Bring an idea, a sketch or a requirements list. We shape it into an architecture and a plan, then carry it through design, prototyping and production with the same team.
Talk to engineeringNo need to start from zero. We reverse-engineer what’s there, preserve what already works, replace obsolete parts and add modern connectivity — then support it in the field.

Yes. Our manufacturing partner American Green Inc. is ISO 9001:2015 certified and UL approved. All manufacturing processes and testing procedures are fully documented to ISO 9001 standards, and AGI ensures that 100% of the products coming out of its facility meet in-house and customer specifications.
Yes, without starting from zero. We reverse-engineer existing electronics, preserve what already works, and add modern connectivity, control and reliability. For example, we added Wi-Fi to a 30-year-old spa controller by intercepting the protocol between the controller and its keypad, and we brought an aging industrial PCB washing machine back into service by replacing its obsolete HMI with a modern HMI and PLC and rewriting the control software.
We also troubleshoot field failures, develop retrofit solutions and provide engineering support for products already in the field. Browse our legacy modernization projects
Yes. We support rapid prototyping, prototype assembly and testing, test fixture development, validation and DFM improvements, then scale into low-to-medium and high-volume turnkey production. PCB assembly covers SMT, through-hole and mixed technologies, with testing that can implement your own product test protocols.
Tell us about your volumes and timeline and we will recommend the right path from prototype to production.
We work with STM32, ESP32 and Microchip microcontrollers, FreeRTOS, Wi-Fi, Bluetooth/BLE, 5G, MQTT, USB, CAN, UART, SPI, I²C, Ethernet and industrial communication interfaces, as well as iOS and Android. We design PCBs and flex circuits in KiCad and model mechanics in FreeCAD, and we have experience with components from Analog Devices, Infineon, Microchip, NXP, Renesas and Texas Instruments.
Yes. We build the software around your product: cloud services, web portals, iOS and Android applications, databases and MQTT integrations for monitoring, configuration, control and data management. Recent work includes the cloud infrastructure and web portal for a 5G-connected irrigation controller with remote fleet management, and a connected spa app with push notifications and MQTT-based home automation integration.
Yes. We combine schematic and PCB analysis, SPICE simulation, hardware debugging and real-world testing to isolate the failure mechanism. On a handheld barcode scanner with power glitches between cradle and battery operation, we delivered a detailed failure analysis with validated rework and PCB modification recommendations. We also provide manufacturing troubleshooting for products already in production.
Either way works. Using trusted long-term vendors, AGI can supply customer-specific plastic and/or metal enclosures that meet or exceed your requirements, or we can work on a consignment basis if you prefer to supply the mechanical components. For turnkey builds, our MRP system and long-term supplier network handle material management and the supply chain, and final assembly and packaging are done in house so products are point-of-sale ready.
All products ship FOB San Diego, CA, via freight forwarding carriers or UPS/FedEx depending on size, anywhere in the continental US and abroad. Packaging, labeling, shipping documentation and scheduling are coordinated with you to ensure accuracy.
Tell us about your product, your volumes and your timeline. You can reach our sales team or talk directly with an engineer, and we will review your requirements and follow up with the next steps.
