Core Services

Engineering Across the Full Stack of Embedded Systems.

From schematic capture through shipping firmware, we work at every layer — connecting electrical design, embedded control, and software integration with clear engineering discipline.

Hardware Engineering

Custom PCB layout and schematic design tailored for manufacturing. We handle component selection (BOM optimization), signal integrity, and design for EMI/EMC compliance to ensure your hardware passes FCC/CE certification seamlessly.

Embedded Systems & Firmware

Bare-metal and RTOS-based embedded firmware in C/C++. Drivers, HALs, bootloaders, and real-time control loops — validated against hardware targets with deterministic timing requirements.

Microcontroller embedded firmware engineering

Software Solutions & Integration

End-to-end software environments that bring your hardware to life. We develop companion desktop applications, robust APIs, and cloud-connected IoT infrastructure (AWS IoT, Azure) for real-time data processing and remote device management.

NDA-First Engagement

Mutual NDAs are executed before any technical discussion. No proprietary detail is shared or received without binding confidentiality in place.

Full IP Assignment

All work product — schematics, firmware, software, and documentation — is assigned to the client upon project completion with no retained rights.

Secure Development Practices

Isolated development environments, encrypted file transfer, access-controlled repositories, and strict need-to-know information handling.

Agile & Transparent Delivery

Clearly defined statements of work, milestone-based deliverables, and audit-ready documentation for every phase of the engagement. We adapt to your time zone for smooth collaboration.

A curated selection of production-deployed engineering work spanning hardware design, embedded firmware, and high-performance software systems.

01 Featured Completed Work

High-Speed NVIDIA Jetson Orin NX Carrier Board

Challenge

Engineering a custom, cost-efficient carrier board for NVIDIA Jetson Orin NX / Nano modules to handle high-bandwidth data streams, while strictly optimizing the Bill of Materials (BOM).

Hardware Execution

Successfully routed high-speed PCIe Gen4 interfaces for NVMe SSD storage on standard, cost-effective FR-4 substrate. Achieved exceptional signal integrity and data transfer rates near PCIe Gen4 limits without relying on expensive, high-loss materials.

Firmware & Systems

Developed a robust system management architecture using an STM32 microcontroller for power sequencing and hardware monitoring, customized the low-level bootloader firmware, and deployed the core Embedded Linux environment along with custom application software.

Impact

Delivered a production-ready, highly optimized hardware platform that achieved a 50% reduction in production costs for volume manufacturing compared to off-the-shelf development kits.

02 Featured Completed Work

Industrial Cellular IoT Tracker & Cloud Infrastructure

Challenge

Designing a compact, high-reliability B2B personnel and asset location tracking platform (based on the Nordic Thingy:91 & nRF9160 architecture) optimized for demanding industrial environments.

Hardware & Firmware

Integrated ultra-low-power cellular connectivity (NB-IoT/LTE-M), GPS, BLE for contact tracing, and NFC into a slim, credit-card-sized enclosure. Advanced firmware design under an RTOS achieved power optimization, extending battery life up to 12 months on a single 600 mAh charge.

Systems Architecture

Engineered embedded IMU sensor fusion for inertial indoor navigation between BLE beacons. Developed the secure backend infrastructure and cloud server web software on AWS to manage device onboarding, telemetry data gathering, and real-time mapping.

03 Featured Completed Work

Real-Time Fiber Optic Distributed Acoustic Sensing (DAS) System

Challenge

Porting, optimizing, and expanding a high-throughput, real-time data analytics software suite for a Distributed Acoustic Sensing (DAS) system. Based on basic OEM baseline hardware-software integration, the enhanced system successfully localized and classified acoustic/mechanical threats including excavators, drilling, and structural failures via laser signal reflections along critical infrastructure lines.

Hardware & Kernel Integration

Engineered a robust, cross-platform software wrapper enabling seamless hardware abstraction layer (HAL) integration with multiple Jungo WinDriver versions. Successfully migrated the entire high-bandwidth PCIe DMA data pipeline from Windows to Embedded Linux (Ubuntu), requiring custom kernel compilation and Contiguous Memory Allocator (CMA) configuration for zero-copy, low-latency FPGA-to-host memory transfers.

DSP & Analytics Execution

Built an ultra-fast digital signal processing (DSP) pipeline over the baseline software by integrating the FFTW library with optimized execution planning. Developed custom pattern recognition and classification algorithms to accurately distinguish between heavy industrial machinery, horizontal directional drilling, and discrete acoustic signaling such as coded vibration sequences.

Software Architecture & UI

Refactored the core application into a high-performance, multi-threaded C++ system featuring advanced DSP filtering, modular runtime configuration processing, and automated telemetry dispatch over MQTT, UDP, and TCP networks. Designed a dynamic, highly responsive interface with real-time data visualization plotting and complex runtime UI element generation and layout reconstruction.
